Feed Through Capacitors

Feed through capacitors (FTCs) are components that allow currents or voltages to pass through them while providing high-frequency filtering, decoupling, and sound cancellation. They are constructed by mounting two capacitors in series onto a conductor. The capacitor in the middle of the series, called the base or scaffold, provides the current/voltage conduction path. The other two capacitors, called inserts, provide the high-frequency filtering, decoupling, and sound cancellation effects.

These capacitors come in various forms, sizes, and materials, and their application fields and working principles depend on their construction. One of the more popular models, the SFKBC5000680MC0, is a type of feed through capacitor that is used for high voltage AC line filtering, decoupling, and sound cancellation. As such, it is most commonly used in medical, industrial, power equipment, and automotive applications.

The working principle of the SFKBC5000680MC0 is simple. Currents or voltages pass through the base and into the two inserts, which then filter the currents/voltages without any significant impedance. This means that the capacitor is effectively able to filter high-frequency noise, decouple various systems, and effectively cancel sound on an electrical level.

The SFKBC5000680MC0 also has a relatively high working temperature of up to 120°C, making it highly suitable for applications that require high-temperature operation. It also has a high dielectric strength of over 5kV, ensuring that it functions reliably even under high voltage conditions. Additionally, its rated capacitance is 680pF, and it has a self-resonant frequency of 30MHz, further emphasizing its suitability for high-frequency filtering.

In conclusion, the SFKBC5000680MC0 feed through capacitor is a popular choice for high-voltage applications due to its ability to filter high-frequency noise, decouple components, and cancel sound. It also offers an impressive dielectric strength and temperature resistance, and its rated capacitance and self-resonant frequency make it highly suitable for a variety of applications.
