DEVICE HAVING A CIRCUIT BOARD AND AN ELECTRONIC CIRCUIT WITH AN ELECTROLYTIC CAPACITOR ARRANGED ON THE CIRCUIT BOARD

摘要

A device has a circuit board and an electronic circuit arranged on the circuit board. The electronic circuit includes an electrolytic capacitor. The electrolytic capacitor is brought to the operating temperature in the case of low temperatures by intrinsic heating as a result of its operation in a detuned circuit.
