Feed Through Capacitors

Feed through capacitors, which are sometimes referred to as FTH capacitors or just FTDs, are electrical components used to reduce voltage and current in a circuit. These capacitors are connected perpendicularly through a through-hole that allows alternating current to flow freely. The purpose of feed through capacitors is to reduce noise, EMI, and other types of disturbances in a confined area, such as a computer system board or server rack.

The SCI-9920-101 is a feed through capacitor that meets many requirements for high power applications. It is designed for use in hot and cold environments, as well as in internal, external, and mobile applications. The feed through capacitor works by actively suppressing EMI and other types of electrical noise by creating a high capacitance field around the device. This field is created using the capacitor’s internal pass circuits.

The SCI-9920-101 is a low impedance component, and as a result, it can help reduce the amount of inductive noise, or “buzzing” caused by electrical currents. By reducing induction, the feed through capacitor can also help to reduce the power draw of the system without affecting the performance. As an added benefit, this device can also prevent interference from outside sources, such as broadcast and mobile radio signals.

The SCI-9920-101 feed through capacitor utilizes a metal-oxide varistor (MOV) in combination with a ceramic capacitor to achieve an unusually high amount of capacitive energy. The MOV helps to increase the amount of energy that can be stored, which in turn increases the amount of electrical noise that can be attenuated. The ceramic capacitor acts as a filter to further reduce the amount of EMI and other interferences.

In addition to its uses as a noise cancelling component, the SCI-9920-101 can also function as a voltage regulator. When connected in series with a load, the capacitor can help mitigate power surges and other voltage variations. This can help to improve system stability and performance, and ensure that no components are damaged due to excessive voltage levels.

The SCI-9920-101 feed through capacitor is a durable and versatile device that is used in a variety of applications. It is designed to work in extreme temperatures, ranging from -40°C to +105°C, and has a breakdown voltage of 2.5V. Its small size and modular construction allow for easy installation and maintenance, making it an ideal choice for high power applications.
