A chip antenna cross reference needs 6 fields. Walsin’s export states 1 directly, 1 partially, and has no column at all for the other 4. We checked.
We counted every band in Walsin’s 38-antenna export: 14 of 19 real bands hold exactly one part number, one band alone holds 15 of 38.
A single extra space in Walsin’s Filter Type column hides the only 2 RF parts above 6 GHz, of 235. Free cross reference, Hong Kong.
SAW vs BAW filter selection on Walsin’s own export: 3 SAW parts, 5 BAW parts, one exact match on band, and two different missing-value conventions.
We measured Walsin’s RF catalogue for phased array passive components. The ceiling is 8,500 MHz, on 2 of 457 parts. Free cross reference.
We mapped all 35 Walsin varistor voltage steps across 11 footprints. Only 10mm and 14mm reach 33 of the 35 steps.
We counted Walsin’s MOV export: 10 columns, 3 empty on every row, 0 covering clamping voltage, energy or surge waveform.
We measured all 385 footprint-and-voltage combinations in Walsin MOV: 115 do not exist. Free cross reference for varistor buyers in Germany.
We opened Walsin’s high power low TCR current sensor file ourselves. It is 6,289 bytes, zero rows, one of 9 empty exports in a single 111-second batch.
We measured Walsin’s MF and WF thin film exports together. At 3 shared tolerances, the series never share a case size. Free cross reference, Hong Kong.
