DEFINITION

Classification: 361/275.1

For electrical irregularities:

(under subclass 272) Subject matter wherein the undesired operating characteristics are unexpected electrical discharge, corona, or short circuiting.

(1) Note. Excluded are capacitors combined with other electronic devices unless the sole purpose of the other electronic device is to protect the capacitor and the device is an integral part of the capacitor. For example, a resistor shunt integral with the capacitor structure is found here.
