Feed Through Capacitors, such as the compact model 4402-005, are designed for connecting a dc power source to a radio frequency (RF) antenna. It is used to provide dc power to a low impedance load, such as an antenna, at frequencies up to 1 GHz, when compared to coaxial cables. The 4402-005 model is constructed using either a single ceramic insulator with multiple copper layers or two ceramic disk insulators.

DC voltage, usually 12 or 24 volts, is applied to the power end and an antenna is attached to the radio end. The capacitor is inserted in between, providing the link between the dc power source and the RF antenna. The 4402-005 model has an impedance of 50 ohms, which makes it well-suited for converting a low impedance source to a 50 ohm system.

The 4402-005 feed through capacitor works as a low loss capacitor due to its design. The capacitor features copper electrodes on both sides of a ceramic dielectric, which provides superior stability and reliability. As the voltage is applied, a small capacitor forms between the two copper electrodes, allowing dc power to pass through while blocking RF interference. The ceramic dielectric ensures that the capacitor is highly stable and provides high isolation levels between the power end and the RF end.

The 4402-005 feed through capacitor is designed to provide high performance for its small size and form factor. It can be used in a range of applications, from aircraft and defense to commercial and industrial. It is also well suited for filtering power and noise in low frequency dc sources. It also provides high isolation levels between the power and RF sides, reducing the risk of electromagnetic interference (EMI) and radio frequency interference (RFI).

Feed through capacitors such as the 4402-005 are a critical component in any RF system. By providing a reliable connection between the power source and the antenna, these capacitors ensure that the system is operating at its best. With their high performance, small size and form factor, they are an ideal solution for any RF and power application.
