Feed Through Capacitors

Feed through capacitors are electronic components that allow current to pass through them. They are similar to regular capacitors, but they are designed to be installed onto a frequency-dependent circuit load where they can be adjusted. The W2H15C4738AT1F is a type of feed through capacitor specifically intended for radio frequency (RF) and audio-frequency (AF) applications.

Application Fields

The W2H15C4738AT1F is suitable for the insulation of radio-frequency equipment, audio-frequency equipment, and other types of equipment when the insulation distances between the high-frequency signal lines and the earth are shorter than usual. It is a 50-volt capacitor with a maximum operating temperature of 85 degrees Celsius and a capacitance ranging from 1.5 to 10 pF. It is often used as part of a pi-matching network or other high-frequency circuits.

Working Principle

The W2H15C4738AT1F is a non-polarized capacitor, which means that it can be installed in any direction in the circuit. It can also be used in series between two conductors in order to reduce or eliminate electromagnetic interference. The capacitor works by creating a frequency-dependent impedance profile that reflects the flow of energy at different frequencies. Essentially, it acts as a high-pass filter to block out low-frequency signals and allow the higher-frequency signals to pass through.

The capacitor also works by forming an electrical shield around the high-frequency circuit. This shield prevents the noise generated by the circuitry from escaping and interfering with other devices. It also reduces the amount of noise generated by the circuit itself as the capacitor helps to reduce reflections of the high-frequency signals.

Conclusion

The W2H15C4738AT1F is a type of feed through capacitor intended for RF and AF applications. It is suitable for the insulation of radio and audio-frequency equipment as it provides a high-pass filter to eliminate low-frequency noise. Additionally, it can also form an electrical shield to reduce the amount of noise generated by the circuit itself. Therefore, the W2H15C4738AT1F is a great choice for any frequency-dependent circuit load.
