Frequently asked questions

What is the E12 resistor series?: E12 is a preferred number series with 12 values per decade. It covers common 5% and 10% tolerance resistors used in everyday circuits.
When should I use E12 instead of E24 or E96?: Use E12 when availability and cost matter more than fine steps. Choose E24 for denser 5% coverage, or E96 when you need 1% precision.
What resistance range is listed here?: This chart lists complete E12 values with decade multipliers from 0.1Ω to 10MΩ so you can look up practical stocked values quickly.
