Sriperumbudur’s electronics corridor builds mobile devices, adapters and telecom gear, and a modern phone board carries hundreds of 01005 parts. For the 01005 capacitor, Venatech, Walsin’s authorised distributor in Hong Kong, supplies 608 Walsin 01005 MLCC, from 0.2 pF to 100 nF, including 98 at plus or minus 0.05 pF.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for hardware, NPI and sourcing engineers on smartphone, wearable and telecom lines in Sriperumbudur, Oragadam and Chennai. Walsin Technology (Walsin) is the line we are authorised for. The Walsin figures come from our MLCC export, 00_ALL_MLCC_parts_combined.xlsx (24,026 rows, 23,601 distinct part numbers), which we re-measured on 11 November 2026. Every part number below is real.
What is happening in the Sriperumbudur electronics corridor?
Steady investment in phones and their supply chain. India Briefing’s investment guide to the Sriperumbudur industrial corridor, first published on 17 February 2026 and updated on 12 March 2026, names mobile devices, consumer electronics, power adapters and telecom equipment as the cluster’s electronics sub-sectors and reports a Foxconn capital commitment of about 150 billion rupees in Tamil Nadu.
The India Briefing guide, read on 11 November 2026, puts the Foxconn commitment at roughly 1.8 billion US dollars with about 14,000 jobs, though it does not say how much of that sits in Sriperumbudur itself. It describes the corridor as hosting several hundred operating units across SIPCOT parks and electronics special economic zones, and says Tamil Nadu secured over 10 trillion rupees of investment commitments across all sectors between 2021 and 2025. These are the publication’s figures.
Why does a phone board use so many 01005 capacitors?
Because space is the scarcest resource on the board. A 01005 capacitor measures 0.4 by 0.2 mm, less than half the footprint of an 0201 at 0.6 by 0.3 mm, and phone designers use it for decoupling around application processors and memory and for matching networks in the RF front end, where every square millimetre goes to the antenna and battery.
Two families do most of that work. Decoupling uses class II parts, X5R or X7R, from about 1 nF to 100 nF at low voltage. RF matching and filtering uses class I NP0 (C0G) parts from fractions of a picofarad to a few hundred picofarads, where tolerance in tenths or hundredths of a picofarad sets the tuning. Our post on NP0, X7R and X5R dielectrics explains the split.
How many Walsin 01005 MLCC can Venatech supply?
608 distinct part numbers in two series. We counted 608 Walsin 01005 MLCC in our export: 317 in the ultra-small 01R5 series and 291 in the RF02 microwave series; 567 are NP0, 32 are X5R and 9 are X7R, and the 01R5 parts are 0.20 mm thick.
By voltage, the 01R5 series has 128 parts at 16 V, 115 at 25 V, 30 at 50 V, 27 at 10 V, 15 at 6.3 V and 2 at 4 V; the RF02 series splits 147 at 16 V and 144 at 25 V. Values run from 0.2 pF to 100 nF, and 98 parts are specified at plus or minus 0.05 pF, which is the tolerance an RF matching network often needs.

What should you check before second-sourcing a 01005 MLCC?
DC bias, tolerance code and the assembly process. The 100 nF 01005 parts are rated 4 to 10 V, and a class II capacitor this small can lose a large share of its value under DC bias, so measure effective capacitance at your rail voltage and read the bias curve on Walsin’s datasheet before you swap brands.
For RF parts, match the tolerance letter, not just the value: in our export A is plus or minus 0.05 pF, B is 0.1 pF and C is 0.25 pF, and a matching network tuned with one will drift with another. For assembly, 01005 parts need a stencil and placement program tuned to their size; a new supplier’s part with the same nominal dimensions can still behave differently in tombstoning, so run a placement trial. Our post on MLCC DC bias and voltage derating covers the bias method.
How can Venatech help a Sriperumbudur EMS line?
How Venatech helps is speed on the cross and clarity on every field. VenaMatch at /cross-reference/ decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, returning every field marked match or mismatch, so a 01005 part from your current maker comes back with its Walsin code, dielectric, tolerance and voltage side by side.
Paste up to 500 part numbers, or upload a full phone BOM at /bom/.
