Frequently asked questions
Is this capacitor suitable for AC mains use?
Only if it is rated for AC mains, such as an X2-class part. MKT capacitors are usually rated for DC voltage, so confirm the datasheet before using it on AC lines.
Can I use it in place of a 223 ceramic capacitor?
Yes for the same 22 nF value, as long as the voltage rating is at least as high as the original. Check the physical size and the circuit's frequency needs.
