MLCC Stock for Vietnam Phone Assembly in Bac Ninh: 106 Walsin 0201 Parts Ready From Walsin’s Authorised Distributor in Hong Kong

MLCC stock for a Vietnam phone line is mostly 0201 and 0402, and the small sizes are where a missing reel stops an SMT line. Our Hong Kong ready stock list as at 9 November 2026 carries 106 Walsin 0201 part numbers: 100 MLCC and 6 chip resistors. Venatech is the authorised Walsin distributor in Hong Kong.

Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a buyer or SMT engineer at a phone, wearable or electronics assembly plant in Bac Ninh. Walsin Technology (Walsin) is the line we are authorised for, and these 106 lines are Walsin parts on our ready stock list. For anything else on the BOM, our supplier network in Hong Kong sources most passive-component brands on request, including urgent spot buys; Walsin comes through our authorised channel. We counted the figures below on 13 November 2026 by matching our ready stock list as at 9 November 2026 (1,174 distinct Walsin part numbers) against our MLCC export, Venatech_MLCC_Upload_01.xlsx to Venatech_MLCC_Upload_08.xlsx, and our chip resistor export, Venatech_ChipR_Upload_01.xlsx to Venatech_ChipR_Upload_79.xlsx.

How much do Bac Ninh’s phone and electronics factories export?

Bac Ninh exported about 75.4 billion US dollars of goods in the first eight months of 2026, up 31.84 percent year on year, according to the province’s Department of Industry and Trade as reported by Bac Ninh newspaper on 28 August 2026. Phones and components made up about 47.3 billion US dollars of that, and computers, electronic products and components about 23 billion.

Those are the province’s figures, not ours. On those numbers, phones and electronics make up more than nine-tenths of the eight-month total. A phone main board carries a dense field of small capacitors, most of them 0201 and 0402, and the line that places them runs at a pace where one missing reel stops the whole build. That is the demand this list is built to meet.

Which Walsin 0201 parts are on the Hong Kong ready stock list?

We counted 106 Walsin 0201 part numbers on our ready stock list as at 9 November 2026. They are 68 general-purpose MLCC (39 C0G/NP0, 15 X7R, 13 X5R, 1 X6S), 27 microwave RF-series MLCC, 4 high-Q HH-series MLCC, 1 ultra-microwave UF-series MLCC and 6 thick-film chip resistors at 1 percent.

General purpose, X5R	13	2,200 pF to 2.2 uF, 6.3 to 25 V	0201X104K6R3	Match

We publish part numbers, not quantities. The ready stock list is a dated snapshot, not live-synced, and we confirm availability, date code and lead time on each quote.

Which 0201 briefs does the list answer for a phone board?

We checked nine typical 0201 phone-board briefs and eight return a Walsin part on the list. Decoupling at 100 nF, bulk at 1 uF and 2.2 uF, RF matching in the single picofarads, and a 10 kilohm pull-up all land on a listed part; a 100 nF X7R brief does not.

Brief	Walsin part on the list	Dielectric or type, tolerance, rating (our export)	Match / mismatch	Your current part
100 nF, X5R, 10 percent, 6.3 V, 0201	0201X104K6R3	X5R, 10 percent, 6.3 V	Match
100 nF, X5R, 10 percent, 16 V, 0201	0201X104K160	X5R, 10 percent, 16 V	Match
1 uF, X5R, 10 percent, 6.3 V, 0201	0201X105K6R3	X5R, 10 percent, 6.3 V	Match; check DC bias
2.2 uF, X5R, 20 percent, 6.3 V, 0201	0201X225M6R3	X5R, 20 percent, 6.3 V	Match; check thickness

4.7 pF, high-Q, 0201	HH03N4R7C500	C0G/NP0, 0.25 pF, 50 V	Match on value; HH series
10 kilohm, 1 percent, 0201	WR02X1002FAL	1 percent, 200 ppm, 1/20 W	Match
100 nF, X7R, 0201	none on the list	X7R tops out at 10 nF on the list	Mismatch: request a quote through our authorised Walsin channel

At 100 nF the list holds X5R in three voltages rather than X7R. X5R is rated to 85 C, which many handset designs accept for decoupling, but take it to your design owner rather than switching quietly.

What should a Bac Ninh buyer check before switching an 0201 MLCC?

Three fields catch most 0201 problems on an SMT line: thickness, DC bias and the placement program’s part data. We check value, dielectric, tolerance and voltage against our export; thickness and capacitance under DC bias come from Walsin’s datasheet, and the feeder and vision data come from your own line.

• Thickness: 1 uF and 2.2 uF in 0201 can be taller than the 0.3 mm a nozzle and stencil expect.
• DC bias: a 6.3 V X5R part loses a share of its capacitance at working voltage; our post on MLCC DC bias and voltage derating explains how to read the curve.
• Ordering code: catalogue codes on the list omit the CT packaging suffix; our post on the Walsin CT suffix shows the orderable form.
• Approval: a cross is a candidate, not an approval; your customer’s AVL decides.

What if the 0201 part is not on the list?

Most 0201 lines a phone BOM needs can still be quoted, because the ready stock list is a fraction of what we can supply. When a Walsin part is not on the list, request a quote and we source it through our authorised Walsin channel; when the BOM names Murata, Samsung, Yageo, TDK or another brand, our supplier network in Hong Kong sources it on request.

We are authorised for Walsin only, so we state date code and origin on every quote for another brand. We give no lead-time or stock promise for either route.

How Venatech helps: how does a Bac Ninh factory order 0201 stock?

How Venatech helps: send the BOM, get the listed Walsin lines quoted from Hong Kong, and get the rest crossed or sourced in the same reply. Venatech is the authorised Walsin distributor in Hong Kong; VenaMatch decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, field by field.

Upload the board’s BOM, paste single lines into the cross-reference tool, or send the request-a-quote form on the site. The MLCC range lists every Walsin family. We serve from Hong Kong in small lots and quote fast; we confirm availability, date code and lead time on each quote and give no price, stock or delivery guarantee.
