Feed-Through Capacitors Overview

Feed-through capacitors are an essential component in the design of electronic circuits. They are usually made from two metal plates attached to a ceramic core, surrounded by an insulating material. The ceramic core acts as a dielectric, which allows electricity to pass through without allowing it to short circuit or otherwise affect the circuit.Feed-through capacitors have been used in a variety of applications, including audio, video, and RF circuits. They are most commonly used to filter noise reduction and transient voltage protection. The majority of commercial feed-through capacitors are rated for voltages up to 3kV.

The SFJNC1K00473MX0 feed-through capacitor is a high voltage capacitor designed for filtering and transient voltage protection applications. It is made from two metal plates attached to a ceramic core, surrounded by an insulating material. The capacitor is rated for operation at up to 3kV and is suitable for use in applications where high voltage protection and noise reduction are required.The capacitor offers excellent noise reduction performance, with a low impedance at high frequencies and low capacitance. This makes it suitable for use in sensitive electronic circuits, such as those used in audio or video applications. It also offers excellent transient voltage protection, providing protection up to 3kV even in the event of a sudden surge.

Working Principle of SFJNC1K00473MX0

The SFJNC1K00473MX0 feed-through capacitor works on the principle of electrical capacitance. Capacitance is the ability of two conducting plates to store energy when a potential difference is applied across them.This capacitor is made with two metal plates attached to a ceramic core, surrounded by an insulating material. The ceramic core acts as a dielectric, which allows electricity to pass through without allowing it to short circuit or otherwise affect the circuit.The capacitor works by storing this electrical energy when a potential difference is applied across the two plates and then releasing it as the potential difference decreases. This process allows the capacitor to filter out noise and protect circuits against voltage surges.

Conclusion

The SFJNC1K00473MX0 feed-through capacitor is a high voltage capacitor designed for filtering and transient voltage protection applications. It is rated for operation at up to 3kV and offers excellent noise reduction and transient voltage protection. It works on the principle of electrical capacitance, storing energy when a potential difference is applied across two metal plates and then releasing it when the potential difference decreases. This makes it suitable for a variety of applications, particularly those where high voltage protection and noise reduction are required.
