The capacitor model is 0.22UF, CBB62 metallized polypropylene film AC capacitor. The capacitor you are talking about is usually in the AC high-frequency anti-interference filter circuit behind the TV power switch. The role of the capacitor in the circuit is filtering. The purpose of the circuit is to filter out the high-frequency interference burrs in the AC, so that the AC becomes more pure, because the TV high-frequency head needs to receive high frequency weak radio signals. The noise factor of the TV high frequency head is very important, and the power filter device installed on the TV can reduce various large disturbances in the power supply, which has a great impact on the sensitivity of the TV receiving circuit.
