Feed Through Capacitors

Feed through capacitors are one-piece, high-capacity air or dielectric capacitors used to eliminate electrical interference caused by high-voltage switching, such as in electrical systems or high-voltage power distribution. Feed through capacitors feature an internal structure that allows for a solid electrical connection from the two sides of the capacitor. This internal structure is composed of two or more electrodes (each consisting of a pair of electrodes), each of which is connected to one side of the capacitor, and an insulator (typically ceramic, mica or insulating glass) that separates the two electrodes.The PSM4-252P-20B feed through capacitor is a single-piece capacitor with a maximum capacitance of 252pF (and capacitance tolerance of ±20 %). It is designed to provide a high-voltage and low-impedance path between two points in an electrical system. The PSM4-252P-20B can be used in high-voltage circuit applications such as motor control, motor starting, instrumentation, power rectification, switchboard wiring, and power protection. It is also suitable for grounding applications such as safety grounding, neutral point grounding, and harmonic filters.The PSM4-252P-20B feed through capacitor works by passing a low-level voltage through the capacitor. The voltage passes through the inner electrodes of the capacitor, which are separated by an insulating material. This creates an electric field caused by the electrons in the insulating material, which prevents the current from going through the capacitor. Because of this, the voltage passes through the capacitor without any resistance or impedance, and is then conducted to the other side. The PSM4-252P-20B feed through capacitor also works to decrease the level of electrical interference caused by high-voltage switching in electrical systems. The capacitor helps to reduce electromagnetic interference (EMI) or radio frequency interference (RFI) by blocking out high-frequency signals that can interfere with other signals. This prevents the electrical signals from being distorted or subject to noise. In addition, the PSM4-252P-20B feed through capacitor can be used for surge protection. During a surge, the voltage across the capacitor can be raised to a specified level which provides a path for current to pass through without damaging other components. The surge current will then be dissipated in the capacitor, preventing damage to any other components in the system. The PSM4-252P-20B feed through capacitor is an essential component for protecting electrical system from interference. It is able to provide effective protection without introducing any additional resistance or impedance into the system. Its low profile and design make it a simple and cost-effective solution for a variety of high-voltage circuit applications.
