Feed Through Capacitors

A feed through capacitor is a type of electrical device, typically used in telecommunications, signal processing, and computer systems. It is a type of capacitor in which electric current passes through a conductor coated with insulative material. A feed through capacitor is functionally like two regular capacitors connected in parallel, but instead of occupying two separate parts, the two capacitors are combined into a single component. The two plates that form a feed through capacitor are connected in series with each other and the core structure consists of two layers of insulator. Because of their construction, feed through capacitors are often used as high frequency filters,where two pieces of conductive material are separated by a dielectric.

DB016040BC80138BJ1 Application Field and Working Principle

The DB016040BC80138BJ1 feed through capacitor is used to filter high-frequency signals in radio-frequency systems. It is constructed with a metalized dielectric core, consisting of two parallel plates made from alumina or other non-conductive material. This design allows high frequency noise to pass through the capacitor while blocking current from other sources. It is designed for applications where high frequency signal isolation is required, such as in radio receivers, filters, and antennas.

The DB016040BC80138BJ1 feed through capacitor has a very stable capacitance at high frequencies, making it ideal for use in RF systems. The dielectric material between the two plates creates a specific capacitance that varies with frequency. This value is determined by the gap between the two plates, as well as the dielectric constant of the material between them. It provides excellent filtering at high frequencies, yet can still pass power through at low frequencies. Additionally, the DB016040BC80138BJ1 is designed to withstand high temperature and humidity.

When a current passes through the feed through capacitor, it allow electrons to move from one plate to the other, creating an electrical field between them. This field is then transferred into the surrounding conductor, isolating the high frequency signals from the power source. Thus, the feed through capacitor acts as a filter, allowing high frequency signals to pass through while blocking other sources of current.

In conclusion, the DB016040BC80138BJ1 is a feed through capacitor specifically designed to filter or isolate high frequency signals. It is constructed with a non-conductive dielectric core, which increases capacitance at frequencies above those of standard capacitors. Additionally, it is designed to withstand high temperatures and humidities, making it an ideal solution for high frequency filtering or signal isolation applications.
