Feed Through Capacitors - SFBDP5000660ZC0 Application Field and Working Principle

Feed-through capacitors, also known as EMI/RFI suppressors or lines filters, are broadly used as components for interference suppression of electrical systems, ensuring that only the allowable electromagnetic interference frequencies will pass through. The SFBDP5000660ZC0 feed-through capacitor is particularly suitable for applications in telecommunications equipment, medical equipment, home electric appliances, computers, and other industries due to its outstanding characteristics.

Functional Principles

The SFBDP5000660ZC0 feed-through capacitor consists of two electrodes at its two ends. Indeed, it acts as a two terminal closing device similar to a switch. When the voltage at the two terminals reaches a certain level, the capacitor will be closed and an electric current will run through it. The SFBDP5000660ZC0 utilizes the contact between the two electrodes to realize the filtering of different impulsive interference signals. During the contact’s break and make moments, the resistance to the electric current increases significantly along with the voltage at the two terminals and an EMI suppressing filter is established.

Main Characteristics

The SFBDP5000660ZC0 feed-through capacitor stands out for the following features:

• It has a rated current of 3 A and a rated voltage of 600 V (DC), a contact resistance of ≤ 5 mΩ, and a 10-sec insulation resistance of ≥ 1000 MΩ.
• It utilizes high-purity aluminum to serve as a dielectric, in order to deliver superior performance and low loss.
• It is RoHS compliant.
• Its temperature range is between -55 °C and +105 °C.
• It is capable of passing different frequencies in the range from kHz to MHz.

Applications

The features of the SFBDP5000660ZC0 feed-through capacitor make it suitable for various applications, particularly in industries with high performance requirements such as telecommunications equipment, medical equipment, home electric appliances, and computers. Besides, its proper choice of materials and excellent quality allow it to serve as a component in civil construction projects and military high security applications.

Conclusion

The SFBDP5000660ZC0 feed-through capacitor is an excellent choice for applications with high performance requirements, as it features an outstanding dielectric property and its contact resistance and insulation resistance make it suitable for different frequencies in the kHz and MHz range. Its wide range of applications in telecommunications, medical, home appliances, computers, military and civil construction projects are proof of the versatile use of this capacitor.
