I choose an input capacitor for the LM2596 DC/DC converter. Since the device will be operated on the street (from -35 to +35°C), I decided to choose polymer capacitors, since they are not particularly dependent on temperature and there is no electrolyte.
Everything seems to be fine, but when compared with electric capacitors, I noticed that polymers have a very high leakage current.
- Electrolytic capacitor - 4uA
- Polymer capacitor - 2350uA
It bothers me. My circuit is protected by a residual current circuit breaker, which is of type A and is designed for a leakage current of 10mA. If there are a lot of capacitors and 10mA is typed, will the switch work? Or am I misunderstood?
