E-Series Resistor Values

Preferred (Renard-style) values repeat every decade, so 10 → 100 → 1 k → 10 k. Each series is spaced so the tolerance bands of adjacent values just touch.

Series	Tolerance	Values per decade (×10ⁿ)
E6	±20%	10, 15, 22, 33, 47, 68
E12	±10%	10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82
E24	±5%	10, 11, 12, 13, 15, 16, 18, 20, 22, 24, 27, 30, 33, 36, 39, 43, 47, 51, 56, 62, 68, 75, 82, 91
E48	±2%	48 values per decade — 10.0, 10.5, 11.0, 11.5, … (10^(n/48))
E96	±1%	96 values per decade — 10.0, 10.2, 10.5, 10.7, … (10^(n/96))
