Resistor Toolkit

DiMastro GTA

Bench tool

Decode a color-banded resistor, or work backward from a target value to the bands you need.

Color Code Decoder

Pick a band count, then click through the swatches to match the resistor in your hand. The reading updates live.

1.0 kΩ
Tolerance: ±5% Range: 950 Ω – 1.05 kΩ

Reading order: on a real resistor, tolerance (and tempco, if present) sits nearer one end with a visible gap before it — that's your cue for which direction to read the digits in. No tolerance band traditionally means ±20%.

Reverse Lookup

Enter the value you need and get the band colors back — handy when you're marking up a schematic or hunting through a parts drawer.

This value is outside the standard multiplier range for that band count.
