Feed Through Capacitors are often used in electric circuits to increase the capacitance of a printed circuit board. They are usually used to reduce noise and interference from surrounding electronics, or to increase the current carrying capacity of a circuit. The PSM4-821M-05T2 feed through capacitors are widely used in the industrial and communications sectors, as they provide an efficient and effective means of increasing capacitance.

The PSM4-821M-05T2 feed through capacitor is composed of three main components: an aluminium shell, a center pin, and a stainless steel end plate. The aluminium shell is where the center pin and the end plate are placed. The center pin is connected to the external edge of the capacitor, and is responsible for the electrical contact between the internal and external capacitors. The stainless steel end plate acts as an electrical separation between the interior and exterior of the capacitor. The whole assembly is then secured with a steel nut and washer to prevent any electrical shorts.

The PSM4-821M-05T2 feed through capacitor has an operating voltage of up to 821 V. It has a capacitance range of 0.1 - 10uF, with a maximum working temperature of 250°C. The device is rated for peak pulse operation of up to 2,500 V and has an insulation resistance of 1,000MΩ. It also has a high dielectric strength of 3,400 Vac. An insulation sleeve made of silicone rubber is used to insulate the pin and the end plate from each other.

The main applications for PSM4-821M-05T2 feed through capacitor include high-frequency switching power supplies, power transmission systems, LCD panels, radio-frequency antennas, and DC-DC converters. In these systems, the capacitor is used to reduce electromagnetic interference, capacitive loading, or to provide a high capacitance to improve system performance. The PSM4-821M-05T2 feed through capacitor is also used in automotive and medical electronics, as well as in other industrial applications requiring high voltage performance.

The working principle of the PSM4-821M-05T2 feed through capacitor is the same as most capacitors. Electrical energy is stored in the capacitor as a result of electrical charge. The electrical charge is created by a voltage differential across the capacitor\'s two plates. The capacitance of the device is determined by the amount of charge stored in the capacitor. When the electrical current passing through the capacitor is increased, the amount of stored charge increases, increasing the capacitance of the device.

The PSM4-821M-05T2 feed through capacitor is a reliable and efficient component for high-frequency and high-voltage applications. It is cost-effective and easy to install, making it an ideal choice for a variety of industrial applications. With its insulation sleeve, the device provides excellent protection against EMI and RFI, ensuring a secure and reliable connection. The capacitor is also available in a variety of sizes and voltages, making it suitable for a wide range of applications.
