4403 Series, Feed Through Capacitors

Feed-through capacitors are specialized devices designed to provide capacitive coupling to a conductor that passes through them. These components are commonly utilized for the purpose of filtering DC power lines, and are known for their ability to offer broad-spectrum filtering capabilities. To ensure optimal performance, feed-through capacitors are often produced in mechanical form factors that are specifically designed to be mounted within a conductive enclosure. This is particularly important in the context of RF, microwave, and other sensitive applications where the presence of unwanted signals can have a significant impact on performance. The capacitors function by offering a low-impedance path for high-frequency signals, while allowing DC signals to pass through with minimal disruption. By doing so, they effectively filter out unwanted noise and interference, therefore contributing to improved overall system performance. In summary, feed-through capacitors are designed to provide capacitive coupling to a conductor passing through them, with broad-spectrum filtering capabilities. They are often manufactured in mechanical form factors and mounted within a conductive enclosure, particularly in the context of RF, microwave, and other sensitive applications. These capacitors play a crucial role in reducing noise and interference, thereby improving the overall performance and reliability of electronic systems.
