Feed through capacitors are an important part of the electronic circuit, providing vital protection for expensive components. 4305-002LF is a kind of feed through capacitor widely used in industrial applications, such as microwaves, CATVs, and satellites systems. It is designed for DC blocking, RF blocking, and AC ripple filtration. Its rated capacitance and voltage value greatly depend on the application field.

Application Fields and Working Principle

The 4305-002LF feed through capacitor is suitable for medium current applications with wide bandwidth up to 400MHz, such as telecom, industrial, and medical equipment. Its conductive impregnation is designed to provide optimal filtering performance with a tight tolerance, giving it a high level of reliability and performance. Its working principle is simple: two aluminum plates are separated by an insulator, and the capacitor is filled with conductive impregnation. This reduces the leakage current by preventing the electrons from going through the capacitor instead of around it. Therefore, the 4305-002LF is able to filter both low and high-frequency noise, thus providing a more stable voltage and current supply to the electronic equipment.In addition, the 4305-002LF can be used for both DC blocking and RF blocking. Its high capacitance-voltage rating allows it to block DC voltages up to 1000V DC. Furthermore, its RF blocking ability is at least 80dB up to 300MHz. This makes the 4305-002LF ideal for use in high voltage applications, such as solar inverters and military equipment.The 4305-002LF is also suitable for AC ripple filtration. Its aluminum plates are designed with an internal impedance range of 0.2-0.4 ohms, making it ideal for filtering out high frequency noise, such as mains noise. By reducing the AC ripple, the 4305-002LF can provide a stable and clean DC voltage source to the circuit.

Conclusion

The 4305-002LF feed through capacitor is an important component for industrial applications. Its wide capacitance-voltage rating and tight tolerance makes it suitable for DC blocking, RF blocking, and AC ripple filtration. It is able to reduce noise and provide a more stable voltage and current supply to the electronic equipment, thus ensuring its proper operation. Therefore, the 4305-002LF is an essential component in many industrial applications.
