A full-text audit of 451 datasheet pages. Named TUV, UL and CQC certificate numbers, MIL-STD-202 methods, and the 18 documents that do not exist.

A census of all 203 Walsin export files held in Hong Kong: 83 return zero rows, 96 column names, and not one column for RoHS, REACH or lifecycle status.

At 2400-2500 MHz, 1608 is the only case size in Walsin’s RF export carrying a filter, a balun and a coupler. Holding to it costs 0.87 dB of chain loss.

Walsin publishes no MOQ or pack quantity anywhere in 203 export files. The only figures exist in a dated distributor snapshot, and they take eight values.

Of 457 rows in Walsin’s RF export, exactly four carry the IoT application tag. All four are 2012 low pass filters, and all four reject only harmonics.

Venatech is in Hong Kong. Its 25 September 2026 stock snapshot splits exactly in two: 442 part numbers carry a pack quantity, 683 carry a date code.

173 S2 safety capacitor rows hold 165 part numbers, and the repeats disagree on thickness. Five checks before you buy a mains-stage part from Hong Kong.

At 575 Vac Walsin publishes three varistors on two footprints. At 550 and 625 Vac, thirteen on nine. Measured for Danish wind and marine.

Six of Walsin’s eleven varistor footprints offer two peak-current grades at one voltage; five offer one. 279 of 379 parts measured, for Polish volume.

Walsin writes 10,000 pF three ways across two safety capacitor families. 929 disc rows and 173 S2 rows measured for a 230 V Dutch mains input stage.
