Feed Through Capacitors are electrical components used to reduce electromagnetic interference (EMI). They are typically used in electrical circuits for high frequency signal transmission. The 4403-031 is one such capacitor, designed and manufactured by Johanson Technology.

4403-031 Design and Features

The 4403-031 is a 3 mm by 3 mm rectangular feed through capacitor. It features a feedthru area of 0.062 in^2 and a resistance of 200 ohms. It is constructed with a dielectric of FR-4 /CEM-3 material, which offers excellent performance in high frequency applications. The 4403-031 also has a high dielectric constant of 7500 VDC. This means that the capacitor can be used in environments where higher levels of EMI are present.

4403-031 Application Fields and Working Principle

The 4403-031 feed-through capacitor is used in a variety of applications including motor control, automotive, medical, and telecommunications. They are typically used in high frequency signal transmission circuits where EMI must be reduced. The 4403-031 works by providing a shielded path for high frequency signals, reducing the amount of EMI that is picked up by other components in the system.

The capacitor works by storing electric charge, which acts as a buffer between the signal and the EMI. When the signal passes through the capacitor, the electric charge is discharged briefly, preventing any interference from reaching other components. The 4403-031 is also capable of passing high frequency signals without any distortion or loss, making it a great choice for applications where signal integrity is paramount.

Conclusion

The 4403-031 feed-through capacitor is an excellent choice for reducing EMI in high frequency signal transmission circuits. Its small size and high dielectric constant make it suitable for a wide range of applications. Its low resistance and ability to pass high frequency signals without any distortion or signal loss make it an excellent choice for any project requiring a reliable EMI shield.
