An automotive ferrite bead search in Walsin’s export returns 289 rows across two series. No column states AEC-Q200. We measured both field by field.
A ferrite bead cross reference needs an impedance curve. Walsin’s export publishes one frequency, 100 MHz, on 609 of 641 rows. Free, Hong Kong.
We parsed 5,410 rows of Walsin’s inductor export for ferrite bead selection. 641 carry an impedance, not inductance. Free cross reference, Hong Kong.
Free cross reference, Hong Kong. Walsin’s SF A Series thin film resistor file is empty. The 2,260 real rows coded A sit elsewhere, letter by letter.
Free cross reference, Hong Kong. Walsin’s AEC-Q200 anti sulfuration resistor export: zero rows. Every real SF row sits in a file not named for it.
Free cross reference, Hong Kong. We checked all 451 Walsin datasheet pages: 29 mention sulfur, 3 name a test — none for the SF thin film resistor.
We measured the mlcc capacitance ceiling by case size across 24,018 rows. General Purpose wins 8 of 16 sizes, zero of the rest. Free cross reference.
We built the full capacitance x voltage grid for general purpose mlcc selection. 145 cells have one part. Free cross reference, ex-stock Hong Kong.
We counted every walsin mlcc duplicate part number in 8,467 rows. 132 repeat; 124 disagree on thickness. Free cross reference, ex-stock Hong Kong.
Chip resistor power rating selection, counted: no anti-surge case size covers more than 5 of 9 wattages. 19 of 63 cells populated. Free cross reference.
