Component Reference Tools — Color Codes & SMD Decoders

Decode resistor color codes, SMD resistor/capacitor markings, AWG wire gauge & world plug standards. Quick lookup for bench and BOM work.

Quick Answer

Axial resistors use IEC 60062 color bands; SMD parts use 3-digit or EIA-96 codes. Always verify critical values with a multimeter.
