All 209 Walsin High Energy, Super High Energy and Industrial varistors start at 130 Vac. Below that: 62 parts, one series. Measured for Sweden.

Six questions to ask a Hong Kong distributor, answered against our own Walsin inductor data — including 4 part numbers that contradict themselves.

Walsin’s 44-row antenna export states peak gain four incompatible ways. 19 rows give a value, 12 give a floor, 5 pack bands into one cell, 8 are blank.

A 5 A filter on Walsin’s inductor export returns 162 part numbers and only 111 are power inductors. The rest are ferrite beads and implausible rows.

Walsin writes inductor DC resistance three different ways. 341 of 5,410 rows use milliohms and 177 use no unit, so a numeric sort ranks them backwards.

Not one of Walsin’s 5,410 inductor part numbers publishes a complete engineering row. What a France rail buyer must request before design-in.

Of 1,125 part numbers in the 25 September 2026 Hong Kong stock snapshot, five sit in an automotive series and none in Walsin’s MT, MG or ST range.

97 of Walsin’s 118 automotive soft-termination capacitors have an SH counterpart identical in size, dielectric, capacitance, voltage and dimensions.

All 3,087 Walsin chip resistors at 25 ppm per degree C are non-automotive. The automotive precision ceiling is 50 ppm, measured across 234,815 rows.

Walsin’s MLCC export carries no metric case-size code on any of 24,026 rows. In the resistor files 0603 names two parts 7.1 times apart in area.
