The 22pF ceramic disc capacitor is a passive electronic component that provides a fixed, stable capacitance value of 22 picofarads. It is commonly used in electronic circuits for bypassing, filtering, and as part of oscillator and resonant circuits, often paired with a crystal to create a clock signal for microcontrollers.
| Voltage Rating | Tolerance | Temperature Coeff. | Lead Spacing |
|---|---|---|---|
| 50V DC | ±5% | C0G (NP0) | 5mm [citation:3] |
| 1kV DC | ±5% | SL | 6.4mm [citation:7] |
| 400V AC | ±5% | SL | 10mm [citation:11] |
| 2kV DC | ±5% | SL/GP | 7.5mm [citation:1] |
| 6kV DC | ±20% | U2J | 9.5mm [citation:2] |
The capacitor is available in a range of voltage ratings to suit different applications. For generalpurpose microcontroller work, a 50V rating is sufficient [citation:3]. Highvoltage variants are used in snubber circuits and power supplies [citation:1][citation:2][citation:4].
