Safety capacitor

For safety and EMC considerations, it is generally recommended to add safety capacitors to the power inlet. At the AC power input end, it is generally necessary to add 3 safety capacitors to suppress EMI conduction interference. They are used in the power supply filter to filter the power supply, and filter the common mode and differential mode interference respectively.

ceramic capacitor

The capacitor ceramics (barium titanate and titanium oxide) with high dielectric constant are extruded into circular tubes, discs or discs as the medium, and silver is plated on the ceramics as electrodes by the sintering method. It is divided into two kinds of high-frequency porcelain and low-frequency porcelain. Capacitors with a small positive temperature coefficient of capacitance are used in highly stable oscillation circuits as loop capacitors and pad capacitors.

Metallized Polypropylene Capacitors

Detection of small capacitors below 10pF: Because the capacity of fixed capacitors below 10pF is too small, measuring with a multimeter can only qualitatively check whether there is leakage, internal short circuit or breakdown. When measuring, you can use the multimeter R×10k block, and use two test pens to connect the two pins of the capacitor at will, and the resistance value should be infinite. If the measured resistance value (the pointer swings to the right) is zero, it means that the capacitor is damaged by leakage or internal breakdown.
