Solar Controller Capacitors for Ghana from Hong Kong: Five Samsung CL Lines Cross to 12 Walsin Parts, 2 Plain-Series Candidates Are on the Shelf and All 5 Allow a Taller Body

Solar controller capacitors for Ghana can be crossed from Samsung CL codes in one pass. Five CL lines decode to 12 Walsin Technology (Walsin) part numbers that agree on size, dielectric, value, tolerance and voltage. Two of the five plain-series candidates are on our Hong Kong shelf, and all five allow a taller body than Samsung’s thickness code.

Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a purchasing or design engineer at a Ghanaian solar-controller, inverter or appliance assembler whose bill of materials carries Samsung Electro-Mechanics CL codes. We decoded five real lines with Samsung’s own numbering document and searched the Walsin MLCC export of 24,026 rows (23,601 distinct part numbers). News statements name their source and the day we fetched it, 23 October 2026.

What is Ghana doing on rooftop solar, and why does it reach the capacitor line?

Ghana has a publicly reported rooftop programme. According to an energy-news report dated 3 November 2025, the Ministry of Energy and the Energy Commission launched a scheme worth 200 million US dollars to put 4,000 photovoltaic units with a combined 137 MW on residential and commercial roofs, with certified companies supplying and installing the systems.

The report says owners with suitable roofs are chosen by open call and that the scheme runs under a bilateral agreement with Switzerland; it gives no completion date. On 25 June 2026 the Ghana News Agency reported a university engineering head urging government to remove taxes on solar panels and accessories, naming import duties, value added tax and regulatory levies as supply-chain costs, with no rates given, and citing power deficits of 8.33 percent in the commercial sector and 2.19 percent in residential areas in an Accra East analysis. Our reasoning, labelled as ours: more installed systems means more charge controllers, inverters and monitoring boards, and each carries a few dozen ceramic capacitors that someone must source. We have no relationship with any Ghanaian ministry or installer.

How do five Samsung CL ordering codes decode?

Eleven fields, and Samsung prints the tables. We decoded five CL codes with Samsung Electro-Mechanics’ MLCC catalogue Part I (December 2025), which defines the series, size, dielectric, capacitance, tolerance, voltage, thickness, design, product, control and packaging codes; none of the five is a Walsin code, so none appears in the Walsin export.

Each code was seen in distributor or aggregator listings on 23 October 2026, which shows it exists; we did not confirm the five with Samsung.

Samsung CL code	Size	Dielectric	Capacitance	Tolerance	Voltage	Thickness code	In Walsin export?
CL10B105KO8NNNC	0603	X7R	1 uF	plus or minus 10%	16 V	8, 0.80 plus or minus 0.10 mm	No (Samsung code)
CL10A475KO8NNNC	0603	X5R	4.7 uF	plus or minus 10%	16 V	8, 0.80 plus or minus 0.10 mm	No (Samsung code)
CL21B105KBFNNNE	0805	X7R	1 uF	plus or minus 10%	50 V	F, 1.25 plus or minus 0.10 mm	No (Samsung code)
CL31A106KBHNNNE	1206	X5R	10 uF	plus or minus 10%	50 V	H, 1.60 plus or minus 0.20 mm	No (Samsung code)
CL32B226KAJNNNE	1210	X7R	22 uF	plus or minus 10%	25 V	J, 2.50 plus or minus 0.20 mm	No (Samsung code)

The last four characters carry design, product, control and packaging codes. Samsung’s table lists C as a normal 7-inch reel; the final letter E on three of the codes is not among the packaging values we read, so we make no packaging statement for those.

Which Walsin parts match each CL line, and how does thickness differ?

Twelve Walsin part numbers agree on the five electrical fields. We counted 12 export rows and 12 distinct part numbers across four series, and each of the five lines has a plain General Purpose candidate; the thickness band is the field that does not line up on any of them.

Walsin writes X7R as B and X5R as X inside the part number, as our post on how to read a Walsin MLCC part number explains.

Samsung line	Walsin General Purpose candidate	Walsin thickness	Samsung thickness limits	On shelf 23 Sep 2026	Other series that agree	Match / mismatch
CL10B105KO8NNNC	0603B105K160	0.80 +0.15/-0.10 mm	0.70 to 0.90 mm	Yes	MT18B105K160, SH18B105K160	Match on size, X7R, 1 uF, 10%, 16 V. Mismatch: Walsin allows 0.95 mm, 0.05 mm taller
CL10A475KO8NNNC	0603X475K160	0.80 +0.15/-0.10 mm	0.70 to 0.90 mm	No	none	Match on size, X5R, 4.7 uF, 10%, 16 V. Mismatch: 0.05 mm taller limit; not on shelf
CL21B105KBFNNNE	0805B105K500	1.25 plus or minus 0.20 mm	1.15 to 1.35 mm	No	MT21B105K500, ST21B105K500, SH21B105K500	Match on size, X7R, 1 uF, 10%, 50 V. Mismatch: Walsin allows 1.45 mm, 0.10 mm taller; not on shelf
CL31A106KBHNNNE	1206X106K500	1.60 +0.30/-0.10 mm	1.40 to 1.80 mm	Yes	none	Match on size, X5R, 10 uF, 10%, 50 V. Mismatch: Walsin allows 1.90 mm, 0.10 mm taller
CL32B226KAJNNNE	1210B226K250	2.50 plus or minus 0.30 mm	2.30 to 2.70 mm	No	ST32B226K250, SH32B226K250	Match on size, X7R, 22 uF, 10%, 25 V. Mismatch: Walsin allows 2.80 mm, 0.10 mm taller; not on shelf

All five plain-series candidates have an upper thickness limit above Samsung’s, by 0.05 mm on the two 0603 lines and 0.10 mm on the other three. On a thin enclosure, a connector stack-up or a conformal-coat clearance, that margin is the number to check. We compared limits by adding each tolerance to its nominal thickness; neither maker’s number is a typical value.

What does the Hong Kong shelf hold for these five lines?

Two part numbers, both General Purpose. Our stock list as at 23 September 2026 holds 0603B105K160 and 1206X106K500; the other three plain-series candidates, 0603X475K160, 0805B105K500 and 1210B226K250, are not on it, and neither is any of the seven automotive or soft-termination alternatives.

We matched the stock list’s 864 MLCC rows to the export and 762 matched, counting by catalogue key. The shelf is a dated snapshot, not live-synced; see the ready-stock list and our post on Walsin passive components in Hong Kong stock. The family overview is in our MLCC range.

We have not seen this counted anywhere: five common solar-controller capacitor lines, 12 exact-spec Walsin part numbers, a plain-series candidate for 5 of 5, a shelf that covers 2 of 5, and an upper thickness limit that is higher than Samsung’s in 5 of 5. For X5R lines near 10 uF and X7R at 22 uF, our post on MLCC DC bias and voltage derating shows why the nominal value is not the working value.

What should a Ghanaian assembler check that this table cannot show?

Capacitance under bias, first. A 22 uF X7R part at 25 V can lose a large share of its capacitance at working voltage, and we matched on nominal value only, so the working capacitance of Samsung’s part and the Walsin candidate may differ. Neither export publishes a bias curve in the fields we compared.

Next, packaging and reel quantity, which the Walsin export leaves empty for all 24,026 rows; ask us for the reel for the code you need. Then series choice: the MT and ST series are named by Walsin for AEC-Q200 automotive use and are not needed unless your customer asks. Qualification stays with you. We hold no office, entity or stock in Ghana, we give no legal, customs or conformity advice (confirm with your compliance team), and we hold no ISO 9001 certificate. Our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. Open the Samsung datasheet and the Walsin datasheet for each pair, because a datasheet states what a part number and an export row do not; our counts come from the Walsin export and the stock list as at 23 September 2026, and from the Samsung datasheet we cite, not from any Walsin datasheet. Send us the Walsin datasheet request and we will return the pages for the series you shortlist.

How Venatech helps

Paste a Samsung, Murata, TDK or Yageo code into the free cross-reference tool, which decodes 18 manufacturers’ part numbers across 800,000+ crossable parts, and read the Walsin candidates with each field marked match or mismatch. Load a whole BOM, up to 500 part numbers or an Excel or CSV file, to run every line at once. The ready-stock list is a Hong Kong snapshot dated 23 September 2026.

Worked example from our own export: the five lines above returned 12 part numbers, and our shelf covers 2 of them. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. We serve from Hong Kong in small lots and cross-reference by hand when a code will not decode. A quote is requested through the site, and the 28 datasheets we hold (451 pages) are sent on request.

The short version

For a Ghanaian solar-controller maker, a Samsung CL line crosses cleanly on the five electrical fields: five lines, 12 Walsin part numbers, 2 plain-series candidates on the Hong Kong shelf. The open items are the taller thickness limit on all five, bias behaviour at 10 uF and 22 uF, and the three lines whose plain-series part is not on the shelf.

Paste your controller BOM into /bom/ or send us the CL lines you want crossed, and we will return the Walsin candidates with the thickness and shelf differences named. If a Walsin part may sit 0.05 to 0.10 mm taller than your Samsung part, does your enclosure care?
