Prepaid meter electronics for Ghana need small C0G capacitors, and our Walsin Technology (Walsin) shelf is patchy there. All 24 E24 values from 10 to 91 pF exist at 50 V, but the shelf covers 5 of 24 at 0201, 11 at 0402, 14 at 0603 and 7 at 0805, and only 18 pF at all four.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this from the Walsin MLCC export (24,026 rows, 23,601 distinct part numbers) and our stock list as at 23 September 2026. It is for a design or sourcing engineer at a Ghanaian maker or assembler of prepaid or smart electricity meters who is crossing a small C0G capacitor. Every part number is real and every count is ours. The market statement names its source and the day we fetched it, 2 November 2026.
What did MyJoyOnline report about Ghana’s prepaid meter replacement, and why does a component buyer care?
It reported a mismatch that cost a re-do. According to MyJoyOnline on 16 October 2026, the Electricity Company of Ghana said it replaced 44,928 prepaid meters in its Accra West region in 2024 because they were incompatible with its Meter Management System, which was commissioned in May 2022, and that the old meters were being redeployed.
Those are the report’s figures as quoted from the company, not ours. The conclusion we draw is ours: compatibility problems are found late, and the small parts in a meter are the ones a maker can fix early by choosing a number that is documented and available. We have no relationship with the Electricity Company of Ghana or any meter maker, and we say nothing about what any of them buys.
Which Walsin C0G capacitors cross a 12 pF, 50 V, plus or minus 5 percent brief at 0603, and what differs?
Eight in the General Purpose series alone. We parsed the 1,881 Walsin General Purpose C0G parts rated 50 V and filtered for 12 pF at 0402 and 0603: 8 part numbers, in tolerances of plus or minus 1, 2, 5 and 10 percent, of which only one, 0603N120J500, is on our shelf. The reader’s incumbent goes in the last column.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|
0603N120J500 |
General Purpose, 0603, C0G, 12 pF, plus or minus 5%, 50 V, 0.80 plus or minus 0.07 mm | Yes | Match on size, dielectric, value, tolerance and voltage | |
0603N120G500 |
General Purpose, 0603, C0G, 12 pF, plus or minus 2%, 50 V | No | Mismatch: tolerance is plus or minus 2 percent, tighter | |
0603N120F500 |
General Purpose, 0603, C0G, 12 pF, plus or minus 1%, 50 V | No | Mismatch: tolerance is plus or minus 1 percent, tighter | |
0402N120J500 |
General Purpose, 0402, C0G, 12 pF, plus or minus 5%, 50 V, 0.50 plus or minus 0.05 mm | No | Match on the electrical fields; mismatch in case size | |
HH15N120J500 |
High Q and Low ESR HH series, 0402, C0G, 12 pF, plus or minus 5%, 50 V | No | Match on the electrical fields; mismatch in series and case size |
A match in the table is a match on the export fields, no more. Confirm against both datasheets and qualify in your own circuit. Our post on NP0 against X7R against X5R dielectrics explains the dielectric codes, and how to cross-reference an MLCC shows the field-by-field method.
Which E24 values between 10 and 91 pF does the Hong Kong shelf cover?
Fewer than half at any one size. We counted the 24 E24 steps from 10 to 91 pF in the 50 V C0G General Purpose export, found all 24 at every size from 0201 to 0805, and compared them with our stock list as at 23 September 2026: the shelf holds 5 at 0201, 11 at 0402, 14 at 0603 and 7 at 0805.
Only 18 pF is on the shelf at all four sizes. Four steps, 13, 16, 24 and 51 pF, are on the shelf at none of them, although the export lists each. We have not seen this counted anywhere. The ready stock list is a dated snapshot, never live-synced, and the MLCC range lists the families, so ask us about a to-order enquiry for a missing step.
What will we not tell you about prepaid meters?
Anything about your metrology class, your communication module or any approval. Of the 28 Walsin datasheets we hold, 26 cover MLCC series, and none names a meter or a utility product, so every count here is catalogue coverage, not suitability.
We make no claim that any part suits a prepaid meter or meets any metering or utility standard. We hold no ISO 9001 or IATF 16949 certificate. We hold no office, entity or stock in Ghana; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no legal, customs or conformity advice; confirm with your compliance team. Qualification stays with you.
Why do buyers in Ghana choose Venatech?
Because we show the gaps in our own shelf. Venatech Limited is an authorised Walsin Technology distributor in Hong Kong, and the Walsin 50 V C0G General Purpose range covers every E24 step from 10 to 91 pF at the four smallest case sizes and 23 of 24 at 1206, 1,881 part numbers in all.
A Ghanaian buyer gets a Hong Kong team that welcomes small lots, answers cross-reference questions field by field, and tells you which step is on the shelf and which is a to-order enquiry. Our VenaMatch tool decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts, and every candidate comes back with each field marked match or mismatch. We would rather you hear about the 2 percent tolerance from us than from your qualification lab.
How can Venatech help a Ghanaian meter maker?
How Venatech helps starts with a free paste box. The cross-reference tool accepts up to 500 part numbers or an Excel or CSV file and shows Walsin candidates with each field marked match or mismatch. Load a whole BOM for a check. The ready-stock list is a Hong Kong snapshot dated 23 September 2026.
Worked example from our own export: the 12 pF, 50 V, plus or minus 5 percent 0603 brief returned 1 stocked match and 4 near parts that differ in tolerance, case size or series. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. We serve from Hong Kong in small lots, we help cross-reference, and you request a quote through the site. We hold 28 Walsin datasheets, 451 pages, and send them on request.
The short version
For a Ghanaian prepaid meter maker, a small C0G value is a shelf question: the export has all 24 steps from 10 to 91 pF, the shelf has 5 to 14 of them by size, and only 18 pF is stocked at all four sizes. A 12 pF, 0603, plus or minus 5 percent brief has one stocked match.
Send us one C0G line from your BOM, with the case size and tolerance you can accept, and we will return the Walsin parts with every difference stated. If your incumbent is a 13, 16, 24 or 51 pF value, have you checked it is stocked at your size?

Frequently asked questions
How many prepaid meters did ECG say it replaced in Accra West?
According to MyJoyOnline on 16 October 2026, 44,928 prepaid meters were replaced in 2024 because they were incompatible with the company’s Meter Management System, commissioned in May 2022. These are the report’s figures as quoted from the company, not ours.
Does the Walsin 50 V C0G range cover every E24 value from 10 to 91 pF?
Yes, at every size from 0201 to 0805: all 24 steps are in the General Purpose export. At 1206, 23 of 24 are present and 11 pF is missing. Confirm each against its datasheet before design-in.
Which Walsin parts cross a 12 pF, 0603, C0G, 50 V, plus or minus 5 percent brief?
0603N120J500 matches on every export field and is on our shelf. Tolerance versions at plus or minus 1, 2 and 10 percent exist, as do 0402 parts. Confirm against both datasheets and qualify in your own circuit.
Which E24 steps from 10 to 91 pF are not on the Hong Kong shelf at any size?
13, 16, 24 and 51 pF, at 0201, 0402, 0603 and 0805, as at 23 September 2026. Only 18 pF is on the shelf at all four sizes. The snapshot is dated, not live, so ask us through the site.
Are the High Q HH and Microwave RF series the same as General Purpose C0G?
No. They are separate series in the export: HH15N120J500 and RF15N120J500 both list 12 pF, 50 V at 0402, but each has its own datasheet. Read the one for your exact part number before you swap.
Do you hold stock or an office in Ghana?
No. We hold no office, entity or stock in Ghana; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen. We hold no ISO 9001 or IATF 16949 certificate and give no legal, customs or conformity advice. Confirm with your compliance team.
