Preferred Values Calculator
This calculator finds the nearest industry standard value for electronic components
(e.g. resistors, capacitors and inductors). To use the calculator simply enter the value you want in
the Enter Ideal Value box. The nearest preferred value should then appear as you type (
if it doesn't check that you haven't blocked Javascript).
Enter Ideal Value:
Examples of the types of component likely to be available for each preferred series are given below:
| E3 | Typically used for high value, low precision capacitors, e.g. electrolytics and Y5V ceramic capacitors |
| E6 | Typically used for tantalum capacitors |
| E12 | Typically used for capacitors, such as X7R ceramic, and ordinary resistors |
| E24 | Typically used higher precision capacitors, such as C0G ceramic, and ordinary resistors |
| E48 | Precision resistors |
| E96 | Precision resistors |
| E192 | Precision resistors |
