Standard resistor finder

Closest E6/E12/E24 value for a target, and the best series or parallel pair.

Target resistance

1 Ω – 10 MΩ

Standard series

Closest single value

6.8 kΩ

= 6.8 kΩ (−9.33 %)

Best pair in series

6.8 kΩ + 680 Ω

= 7.48 kΩ (−0.27 %)

Best pair in parallel

15 kΩ ∥ 15 kΩ

= 7.5 kΩ (+0.00 %)

Combining two standard values often gets much closer to an odd target than any single value, without ordering precision parts.

How it works

Resistors come in standard series. When a calculation gives an odd value, a pair of standard resistors usually gets closer than any single one.
