Vishay Part Number Reference

MPN Structure Overview

Vishay produces a wide range of passive and semiconductor components:

CRCW: Thick film chip resistors
SI: MOSFETs
1N: Diodes (rectifiers, signal, zener)
2N/BC: Transistors
BAT/BYV/BZX: Specialty diodes
VLMU/VLMS: LEDs

CRCW Resistor Format

CRCW [Size] [Value] [Tolerance] [Packaging]
  |    |       |        |           |
  |    |       |        |           +-- Packaging code
  |    |       |        +-- Tolerance (F=1%, J=5%)
  |    |       +-- Resistance value (e.g., 100R, 10K)
  |    +-- Case size (0402, 0603, 0805, etc.)
  +-- Series prefix

Known Handler Issues

1. HashSet in getSupportedTypes()

Uses mutable

HashSet

instead of

Set.of()

2. Transistor/Diode Overlap

2N and 1N prefixes are also used by other manufacturers. Handler may match parts from TI, OnSemi, etc.
