Walsin’s General Purpose Chip Resistor Range: Inside the 75,628-Part Line
Walsin’s general purpose chip resistor line is 75,628 parts across 10 case sizes and 3 prefixes, two-thirds of them E96 rather than E24.

Walsin’s general purpose chip resistor line is 75,628 parts across 10 case sizes and 3 prefixes, two-thirds of them E96 rather than E24.
Walsin’s MLCC land pattern guide publishes footprints for sizes with zero parts and omits two sizes that exist. How to check before you lay out a pad.
Six Walsin MLCC series have a datasheet but zero searchable parts: VT, 0612, OP, S3, SG High Voltage, SH High Voltage. What that means for sourcing.
MLCC capacitance by case size: 100 nF at 01R5 to 220 uF at 1206 and 1210, mapped across Walsin’s 24,025-part catalogue with the part number for each.
Wave solder MLCC is limited to 0603, 0805 and 1206 under 1 mm thick. 2,873 of 13,162 Walsin parts in those sizes fail the thickness test. Check by part.
Walsin’s UF microwave MLCC is narrow-tolerance to 0.02pF, tighter than sibling RF and HH series. All three share a 38-row tolerance-field formatting quirk.
Walsin’s ultra-small 0.4×0.2mm MLCC has three names: 01005 in the guide, 01R5 in the export, and 02 inside RF-series part numbers for 291 more parts.
Walsin’s Big Sizes MLCC covers 1825, 2220 and 2225. Only 2220 reaches the datasheet’s 47uF X7R ceiling; the larger 2225 tops out at 10uF.
Walsin’s Middle to High Voltage MLCC spans 200V to 4kV in 14 steps. One of 4,094 parts writes its voltage as 1300V, not a code in the datasheet’s own key.
Walsin’s general purpose MLCC range is 8,467 parts across 0201-1812 in six dielectrics. 14 parts carry 200-630V, above the datasheet’s 100V ceiling.
