What is a feedthrough capacitor?

The feedthrough capacitor is a three-terminal capacitor that is used to reduce high frequencies. Unlike regular three-terminal capacitors, the component is directly installed on the chassis metal panel, resulting in a lower grounding inductance and a negligible effect on the lead inductance. As a result, the component provides good filtering.

Feed-through capacitor uses

Standard capacitors are not suitable for filtering applications because they tend to introduce high impedance. This impedance, usually in the form of shunt inductance, is undesirable and can significantly affect the performance of a filtering circuit. In comparison, feedthrough capacitors do not have this undesirable inductance in the shunt branch of a filter. The inductance of these components is in the series branch.Feedthrough capacitors are commonly used in today’s AC/DC supply lines to suppress harmful interference. They are also widely used in electronic circuits for base stations, telephone exchanges, shielded rooms, power supplies, and many other applications.RF feedthrough capacitors are mostly used for high power applications such as dielectric and induction heating equipment, plasma generators, and radio broadcast transmitters. They are also widely used for matching high power tuned circuits, bypassing and coupling RF circuits, and coupling antenna circuits.SMT feedthrough capacitors are suitable for a wide range of applications including:
  1. Power decoupling in amplifier circuits
  2. High frequency decoupling in power lines
  3. Filtering in digital to rf interfacing circuits
  4. Voltage conditioning in RF amplification circuits
  5. High frequency decoupling in data, clock, and control lines
