Feed Through Capacitors

Feed through capacitors, also known as bulkhead caps or slot caps, is an important type of capacitor used in electronics to deflect currents that flow between two separated conductors or isolated sections. Feed through capacitors can also suppress the surge currents to protect the electrical system from the damaging effects of an excessive surge.

SFCDL5000472MX1 is one of the feed through capacitors developed by Samsung Electronics. It is designed for high reliability applications such as aviation, military, and industrial environments. With its high range of capacitance range and low leakage current, it is ideal for high frequency RF applications.

Application Field and Working Principle

The SFCDL5000472MX1 is designed for high-density signal control systems used in a wide range of applications. It has a wide frequency range, making it suitable for audio, video, and instrumentation applications. It is also suitable for use in power line circuits, as it can reduce high-frequency interference from other sources.

The SFCDL5000472MX1 has a ceramic hump dielectric, which helps to minimize the capacitance droop associated with traditional ceramic dielectrics. Its spiral construction utilizes four different layers of disk constructed from high-permittivity ceramic material, resulting in a high capacitance in a low-resistive feed-through capacitor. The four layers are connected in series, forming a bridge circuit. The bridge connection reduces the electrical contact resistance to a minimum, ensuring that the entire path of the feed-through capacitance is isolated.

The SFCDL5000472MX1 is designed for high-impedance signal control applications. This type of capacitor is used to couple a sensor to a control system by adding capacitance and reducing noise. The capacitance reduces impedance and allows low-frequency signals to pass while blocking high-frequency signals. This helps to reduce the effects of noise on the sensor signals. Additionally, this type of capacitor is used in matched filter circuits that are designed to isolate AC power lines from noise.

The SFCDL5000472MX1 is designed with an air gap between the two electrodes. This allows the capacitor to maintain a high insulation resistance while reducing the inductance of the feed-through capacitance. This helps to maintain a low level of interference to the system, ensuring reliable operation.

The SFCDL5000472MX1 is suitable for high-reliability applications in a variety of settings. It is designed for audio, video, and instrumentation applications. It is also suitable for use in power line circuits, as it can reduce high-frequency interference from other sources. It has a wide range of operating temperatures, making it suitable for temperature sensitive applications.

In summary, SFCDL5000472MX1 is a feed through capacitor designed for high reliability applications. It is a four layer capacitive bridge configuration that is suitable for audio, video, instrumentation, and power line applications. With its ceramic hump dielectric and wide frequency range, it is an ideal choice for high-impedance signal control applications.
