We parsed all 451 Walsin datasheet pages. 56 state an MLCC operating temperature range, 395 do not, and no export column carries one. Free cross reference.
A passive component cross reference can join on just 2 of 90 columns across Walsin’s eight families: part number and series. Free tool, measured counts.
MLCC pack quantity on our Hong Kong shelf as at 23 September 2026 is set by case size. 16 of 501 lines pack at 1,000 or fewer. Free cross reference.
We decoded the MLCC date code on all 683 Hong Kong stock lines dated 23 September 2026. 22 carry a lot over five years old. Free cross reference.
Wide terminal power resistors beat the equal-area standard footprint on watts in 0 of 3 pairs. 870 cells are wide-terminal-only. Free cross reference.
At 1 milliohm Walsin publishes 3 of the 6 fields a sense design needs. Zero of 10,428 thick film rows reach it. Free chip resistor cross reference.
All 5,941 Walsin chip resistor array signatures have a discrete at the same resistance and tolerance. 3,688 do not at the same TCR. Free cross reference.
We measured thickness against voltage on all 4,094 Walsin high-voltage MLCC rows. 1,733 clear a 1.20 mm worst case. Above 2,000 Vdc, none do. Germany.
We audited Rated Voltage on all 24,025 Walsin MLCC rows against the datasheets. One of 16 series is impulse voltage. 17 rows contradict themselves.
We counted every cell in Walsin’s 44-row antenna export. Only 4 of 10 specification fields are filled on all 44 parts, and 7 parts are indistinguishable.
