Feed Through Capacitors

A feed through capacitor is a type of electrical component which is designed to be inserted into a two-way electrical conductor. This type of capacitor is also known as a bypass capacitor or a high-frequency capacitor and it is used to provide a low-resistance, low-inductance path to ground for a wide range of useful frequencies at the same time. In other words, a feed through capacitor maximizes the frequency response of the device in which it is installed.

A common type of feed through capacitor used today is the physically small and low-profile 4400-017LF type, which is often used in high-frequency radio communication and radar systems. This type of capacitor features a combination of both low lead inductance requirements and a radial, hermetically sealed, low dissipation surface mount package. The 4400-017LF utilizes two single-ended capacitors that are mounted crosswise in the circuit so that they can perform their intended functions while maintaining a low inductance.

The 4400-017LF feed through capacitor\'s primary application is to provide a low-inductance bypass path between power supply lines and ground. This is accomplished by placing a small capacitive element within the through-hole circuit, which acts as a kind of bridge between the two signals. This bridge acts as a shunt, providing a low-power, short-duration connection between the power supply and the ground while still allowing the power supply signal to pass through it without attenuation.

The 4400-017LF feed through capacitor\'s working principle is based on the concept of capacitive reactance. This concept states that capacitors oppose changes in voltage, and therefore store charge when exposed to a voltage. This stored charge is then released back when the voltage decreases. In the case of the 4400-017LF capacitor, this effect is used to provide a low-resistance connection between the power supply lines and the ground.

The 4400-017LF feed through capacitor is a very useful electrical component and is used in a range of communication and radar systems. This type of capacitor is designed to provide a low-inductance bypass path that allows high-frequency signals to pass through with minimal interference. Furthermore, the 4400-017LF feed through capacitor also serves to provide a short-duration, low-resistance connection between the power supply lines and ground.
