Tolerance

Nearest E12 Standard Value

1.000 kΩ

0.0% from decoded value — E12 covers ±10% tolerance components.

Typical Use

Mid-range resistor — the most common range. Typical uses: LED current limiting (220–560 Ω), pull-down resistors on logic lines, base resistors for BJT switches, and op-amp feedback networks.
