Product Description

The QB Products 13QBP21090 Microwave High Voltage Capacitor is used in the circuitry of the appliance to store and discharge the electrical energy required to ignite the magnetron. Connected with the transformer and the diode, it receives the incoming charge and, emits it in controlled pulses, which facilitate the production of microwaves. Its position inside the internal chassis keeps it in touch with the main power path, though it is not in contact with the external interaction. The capacitor serves to stabilise the heating performance of the magnetron by controlling the energy transfer.
