Feed Through Capacitors

Feed through capacitors are devices that permit the passage of electrical current while providing a specific range of frequency-dependent impedance. They are designed to block certain frequencies while allowing other frequencies to pass through. This type of capacitor is often used in radio frequency (RF) and high frequency (HF) applications as well as medical and communications electronics, such as in antenna tuners, resonance circuits, interconnects, and AC power line filters.The SFJEC1K00333MX-1 feed-through capacitor is a high quality, small size, stable performance computer-grade capacitor that is optimized for performance in a wide range of electrical and electronic applications. It is well-suited for installation in tight spaces such as in portable device cages and patch panels, and is capable of withstanding high temperature and pressure, making it perfect for high vibration and shock environments.The SFJEC1K00333MX-1 is a surface clamp type capacitor and can be mounted on flat and curved surfaces. The device is able to work in three different operating modes: direct, switched, and grounded through. The main application is in switching power supplies, such as in power adapters and AC mains filters. It is also useful for harmonic filtering, neutral line balancing, input/output impedance matching, and EMI/RFI protection.The SFJEC1K00333MX-1 has a two-terminal design with two terminal posts insulated from each other and has an insulated synthetic plate as the connecting bridge between the two posts in the center of the device. The capacitor consists of a cermet and polyester film which are sealed together under pressure with a dielectric epoxy resin. The ceramic element provides the electrical stability and the polyester film provides mechanical support and functions as the dielectric. The surface clamp capacitor works on the same principle as any other type of capacitor but has the added advantage of being more space efficient due to its small size. The capacitor acts like a filter, blocking any frequencies that are outside of its range, while allowing frequencies within its range to pass through. The dielectric strength of the epoxy resin used to hold the ceramic element and the polyester film together helps to reduce frequency interference and enhances stability.The SFJEC1K00333MX-1 is capable of withstanding high temperature and pressure as well as high vibration and shock environments, making it perfect for use in medical and communications electronics, such as antenna tuners, resonance circuits, interconnects, and AC power line filters. It is an ideal choice for various applications that require reliable high frequency performance.
