Feed Through Capacitors

Feed through capacitors are specialized capacitors that are used to separate an electrical signal into its DC and AC components or current shunt components. They are also used to reduce voltage spikes, inductive pickups, and radio frequency interference (RFI). The SFJEL2K00472MX1 feed through capacitor is a high-quality product designed for use in applications with high ambient temperatures, high voltage spikes, and in low-impedance applications.

Application Field

The SFJEL2K00472MX1 feed through capacitor is used in a variety of applications. These include power conditioning in high voltage and low voltage systems, electric power transmission, telecommunications, and radio frequency (RF) applications. The capacitor is designed for mounting on printed circuit boards, and can handle voltage up to two kilovolts. The device is also designed for long-term operation, with high dielectric strength and life expectancy. The SFJEL2K00472MX1 is available in two standard sizes and is also available in an axial style.

Working Principle

Feed through capacitors are constructed using stacked dielectric insulated plates or flexible polymers. When voltage is applied, electric charge builds on the capacitor’s plates. This electric charge acts as a buffer, allowing an electric circuit to continue to conduct uninterrupted electrical signals, while also preventing surges and spikes from reaching electronics further downstream. The SFJEL2K00472MX1 feed through capacitor features an internal varistor for additional protection against electrical surges and Electro Magnetic Interference (EMI).

When a voltage spike occurs, the capacitor’s varistor becomes activated. The varistor acts as a resistor, allowing the voltage spike to pass through without affecting the circuit. Once the voltage spike is passed, the capacitor returns to its uncharged state. This helps to protect the entire circuit from voltage spikes, and helps protect against damage to the circuit itself.

In addition to providing protection against surges and spikes, feed through capacitors also help reduce the amount of noise travelling along circuits. This is achieved by blocking and suppressing high frequency noise and radio frequency interference from other nearby circuits. This helps to ensure that data transmitted across the circuit remains accurate and interference-free.

Conclusion

With its high voltage rating and internal varistor, the SFJEL2K00472MX1 feed through capacitor is a reliable and dependable product. The device is designed for use in a variety of applications, such as power conditioning, power transmission, telecommunications, and RF applications. It helps to protect circuits from voltage spikes and EMI, and can also help reduce circuit noise. As such, the SFJEL2K00472MX1 feed through capacitor is an ideal choice for any application requiring this level of protection and performance.
