Feed Through Capacitors

The SFJNC0500225MX0 is a feed through capacitor, an electronic component used to pass high-frequency signals from one point to another while blocking direct current. This movable capacitor is found in circuits, mainly used for shielding and high-frequency filtering applications.

Application Field

Feed through capacitors are most often used in radio frequency (RF) applications, namely behind coaxial interconnects, which are widely used to connect RF devices such as amplifiers, antennas, or tuners. The application area for feed through capacitors is also extended to the automotive industry to control noise and EMI on connected parts.

Working Principle

Feed through capacitors operate on the principle of electrical charges. These components allow high frequencies to pass through from one point to another by using a diode or capacitor, making them useful in any number of sensitive applications. The diode or capacitor acts as an impedance, or resistance, blocking the conduction of low and direct currents while allowing high and alternating currents to pass through.

The SFJNC0500225MX0 feed through capacitor is designed to offer high decoupling performance, with its 0.25pF capacitance value and high self-resonance frequency of 10 GHz. Rated for 500V DC voltage, this feed through capacitor is designed to provide reliable and high-performance operation in RF shielded applications.
