101 capacitor value

The code 101 reads as 10 × 10¹ pF: 100 pF, which is the same as 0.1 nF or 0.0001 µF.

Other ways it's marked

On schematics and parts lists, the same capacitor appears as 100p, 0.1 nF or 0.0001 µF.

Where it's used

Values below 1 nF are typical in radio circuits, oscillators and high-frequency filters, usually as C0G (NP0) ceramic capacitors, which stay stable with temperature.

Frequently asked questions

What is the value of a 101 capacitor?

100 pF, the same as 0.1 nF or 0.0001 µF.

Is 101 the same as 100p?

Yes. 101 is the 3-digit code and 100p is the letter code for the same 100 pF.

What does the letter after 101 mean?

It's the tolerance: 101J is ±5%, 101K is ±10% and 101M is ±20%.

Does the code 101 show the voltage?

No. The voltage is printed separately (such as 50V, or a code like 2A, which means 100 V) or only given in the datasheet. Replace it with a capacitor rated for the same voltage or higher.
