Feed Through Capacitors

Feedthrough capacitors are special devices used in high-frequency circuits to join two sides of an alternating current. They are usually used to allow an alternating current (AC) signal to bypass capacitive coupling through a circuit, or to reduce the risk of electromagnetic interference (EMI) from high-frequency circuits. The most common type of feedthrough capacitor is the SFJEL1K00473MX1 capacitor.

Applications of the SFJEL1K00473MX1

The SFJEL1K00473MX1 capacitors are designed for electrostatic discharge (ESD) and electromagnetic interference (EMI) protection in high-frequency circuits. They are widely used in avionics, telecom, and industrial electronics for signal bypass and power line filter applications. The SFJEL1K00473MX1 capacitors are designed to perform in applications requiring fast transient performance, low signal distortion, and high surge current capability.

Working Principle of the SFJEL1K00473MX1

The working principle of the SFJEL1K00473MX1 capacitor is based on the Faraday\'s law of electromagnetic induction. As an alternating current-biased voltage is applied to the feedthrough capacitor, the alternating current will pass through it while the voltage will be discharged due to the Faraday’s law. The capacitor can effectively block high-frequency and radio frequency (RF) waves while allowing the alternating current to pass through it. This helps to reduce the effects of RF signal interference and EMI in high-frequency circuits.

Features of the SFJEL1K00473MX1

The SFJEL1K00473MX1 capacitor has a number of features that make it an ideal choice for EMI and ESD protection in high-frequency circuits. These features include high capacitance values, low series inductance, high surge current ratings, low signal distortion, fast transient response, long service life, low thermal resistance, and high reliability.

Conclusion

The SFJEL1K00473MX1 feedthrough capacitors are ideal for applications requiring EMI/ESD protection at high frequencies. Their high reliability, low series inductance, fast transient response, and low thermal resistance make them suitable for use in a variety of industrial, avionics, and telecom applications.
