Feed Through Capacitors: 4400-093 Application Field and Working Principle

Feed-through capacitors are electronic components which provide a relatively low impedance path between two conductors, allowing direct current to pass through while providing minimal interference. The 4400-093 is a type of feed-through capacitor designed specifically to allow low-frequency AC signals to pass through. This article will describe the working principle, application fields, and features of the 4400-093 feed-through capacitor.

Working Principle

The working principle of feed-through capacitors is relatively straightforward. The capacitor consists of two conductive plates, or electrodes, separated by an insulating material. These electrodes are connected to two different conductors, allowing the capacitor to act as a bridge between them. Low frequency AC or DC signals can then pass through the capacitor, while high frequency signals are prevented from passing by the capacitor’s insulation material.

Application Fields

The 4400-093 feed-through capacitor can be used in a variety of different applications. It is commonly used as a filter to reduce high-frequency noise and interference in electronic circuits. It can also be used to shield electronic components from radio frequency (RF) energy and other electromagnetic interference (EMI). Additionally, the capacitor can be used to improve peak performance and signal integrity in high-speed digital applications.

Features

The 4400-093 feed-through capacitor has a number of features that make it particularly suitable for its intended applications. The capacitance is a relatively low 0.213 pF, with a maximum insertion loss of only 0.2 dB at 500 MHz. It is also designed to operate over a wide temperature range, from -40° C to 85° C. Additionally, the capacitor has a relatively low profile, with a maximum height of 70 mils (1.778 mm).

Conclusion

The 4400-093 is a type of feed-through capacitor designed specifically to allow low-frequency AC signals to pass through, while still providing adequate protection from high-frequency EMI. It is particularly suited for filtering and shielding applications, thanks to its low profile and relatively low insertion loss. With a wide operating temperature range and low capacitance, the 4400-093 is an excellent choice for any application requiring reliable signals in the presence of EMI.
