Feed Through Capacitors

A feed through capacitor, otherwise known as an RF feed through capacitor, is a type of capacitor that is designed to reduce the signal loss that is caused by high frequencies. It is used in a variety of applications, most commonly in radio frequency (RF) circuits and in the electrical engineering industry. The SFABC5000100ZC0 is an example of a feed through capacitor.

Application Field

The application field of feed through capacitors includes telecommunications, radar, microwaves, and industrial filtering. One common use of the SFABC5000100ZC0 in particular is to reduce the signal loss that is associated with transmitting and receiving radio signals. It is also used in a variety of electronic circuits to provide a clean DC signal in industrial and commercial applications.

In addition to its use in radio and industrial applications, the SFABC5000100ZC0 is also a popular choice for board-level filtering, including inter-board decoupling and/or RF interference suppression, and as a soft-fail circuit protection device. The feed through capacitor can also be used in high-speed signal and data components such as digital logic ICs, buffers, and digital-analog converters, as well as in instrumentation and medical equipment.

Working Principle

The SFABC5000100ZC0 feed through capacitor works by connecting two electrodes through a dielectric material, such as a ceramic or glass. When an AC voltage is applied across the capacitor, the dielectric material between the electrodes reacts to the electric field and acts as a barrier, blocking the electric current from passing through it. The electric current is conducted only through the electrode connections, and the capacitor acts as a high-frequency filter, allowing only alternating currents of the desired frequency to pass.

The SFABC5000100ZC0 feed through capacitor has a capacitance of 16pF to work with the desired frequency of 500-1000MHz, allowing for a wide range of applications. Its working temperature range is -55℃ to +125℃, and its rated voltage is up to 3kV peak-to-peak. It is designed to provide low ESR (equivalent series resistance) and low DC leakage in its specified frequency band, and its inductance is less than 1nH over its operating voltage range.
