What are the main characteristics of the chip capacitor? (I)

1. Capacity and error: The maximum allowable deviation range of actual capacity and nominal capacity. The commonly used capacity errors are: J ± 5%, K ± 10%, M ± 20%.

The allowable error of precision capacitors is small, and the error of electrolytic capacitors is large. They use different error levels.

Commonly used capacitors have the same accuracy level as resistors. Expressed by letters: Grade D—±0.5%; Grade F—±1%; Grade G—±2%; Grade J—±5%; Grade K—±10%; Grade M—±20%.

2. Rated working voltage: The capacitor can work stably and reliably for a long period of time in the circuit. The maximum DC voltage to withstand is also called the withstand voltage. For devices with the same structure, medium, and capacity, the higher the withstand voltage, the larger the volume.

3. Temperature coefficient: The relative change in capacitance for each temperature change of 1°C over a certain temperature range. The smaller the temperature coefficient, the better.
