About this product
A 390 nF (0.39 µF) ceramic capacitor with a 400 V rating. Ceramic capacitors of this type are used in filtering, coupling, decoupling and high-voltage circuits where a non-polarised capacitor with a high voltage rating is needed.

Frequently asked questions
Can I use it where a 100 nF capacitor is specified?
No, not unless the circuit tolerates a different value. Capacitance affects filtering, timing and frequency response, so match the value in your schematic.
Is a 400 V rating suitable for a 12 V circuit?
Yes from the voltage standpoint, since 400 V exceeds a 12 V supply. Always make sure the rating is higher than the maximum voltage across the capacitor, including any peaks.
