3. Safety certification 1). As a Y capacitor in the safety capacitor series, it is required to obtain certification from a safety inspection agency. The appearance of Y capacitors is mostly blue and round, and they are marked with safety certification marks (such as UL, VDE, ENEC, CQC, KC, etc.) and

1. Safety capacitors for suppressing electromagnetic interference of power supplyWhen using a safety capacitor to eliminate noise in a power-over line circuit, not only the normal voltage, but also the generation of abnormal pulse voltages (such as lightning) must be considered, which may cause the

Unconsciously summer came and the weather became hotter and hotter. Many friends in the electronics industry may not know that temperature has an effect on capacitors. Under normal circumstances, when manufacturers choose capacitors, they generally consider only the capacitance and withstand voltage

The safety capacitor is one of a large number of electronic components used in electronic devices, and is widely used for blocking, coupling, bypassing, filtering, tuning circuits, energy conversion, and control circuits. Capacitance, also known as "capacity," refers to the amount of charge stored a

2, the safety capacity of the capacitor testThe capacitance of the safety capacitor is usually measured by a digital multimeter or digital capacitance tester. If there is no digital multimeter and digital capacitance tester, an analog multimeter can be used for simple estimation. For a capacitor wit

A capacitor is a kind of energy storage element and it is one of the basic components that make up an electronic circuit. When a voltage is applied across the capacitor, the capacitor absorbs energy from the power supply and stores it in the electric field established between the two plates. When th
