Checking inductor height against a 1.0 mm clearance limit? 2,720 of 5,410 Walsin inductors clear it; 2,690 exceed it. Series-by-series checklist inside.

Ferrite bead vs inductor, from real Walsin data: only 609 of 5,410 rows publish a real 100 MHz impedance figure. The rest read a literal zero.

208 Walsin inductors across 5 series have no walsin inductor datasheet. We measured what the export publishes for them field by field — some, not nothing.

A walsin inductor part number prefix maps to one series in 33 of 36 cases. We measured all 36 against 5,410 real parts. Full decode table inside.

At 0201, every Walsin chip inductor is 0.3mm thick and tops out at 100nH. At 0402 the ceiling is 150nH, held by a single part number.

1,118 of 5,410 Walsin inductors clear 1A rated current. 71 rows need a unit correction first, or you will undercount or misread them.

Walsin’s inductor export has no shielded/unshielded field. Here is what the size-vs-current data shows instead, including a defect we found checking it.

Buck converter inductor selection needs saturation current, not rated current. Only 146 of Walsin’s 5,410 inductors publish it, and only 3 series do.

139 of 139 Walsin MCI Automotive inductors match a commercial MCI part on every electrical field but rated current, which differs on only 5.

Walsin’s published SRF(min) spans 0.015 to 20,000 across 5,410 inductors, and 997 rows read exactly 0. One series tops out at 5.2, far below every other.
