Package Code Extraction

Resistor Size Codes

  • 01 = 0201/0603M
  • 02 = 0402/1005M
  • 03 = 0603/1608M
  • 06 = 0805/2012M
  • 12 = 1206/3216M
  • 20 = 2010/5025M
  • 25 = 2512/6432M

Series Extraction

Returns human-readable series names:

  • "Chip Resistor", "Anti-Sulfur Resistor", "Fusible Resistor"
  • "Shielded Inductor", "Non-Shielded Inductor", "High Current Inductor"
  • "TVS Diode Array", "Metal Oxide Varistor", "Resettable Fuse"

Replacement Logic

  • Anti-sulfur resistors can replace standard chip resistors
  • Shielded inductors can replace non-shielded of same size
  • Checks package, power rating, and tolerance compatibility

Test Patterns

When testing BournsHandler:

  1. Use documentation tests for 
    matches()
    behavior
  2. Use assertions for 
    extractPackageCode()
    , 
    extractSeries()
    , null handling
  3. Instantiate directly: 
    new BournsHandler()
