Feed Through Capacitors

Feed through capacitors, also known as axial DC blocking capacitors, are devices used primarily for DC block applications, where frequencies are typically below 400 Hz but can also be used up to 500 kHz. They are an important component for AC power circuits, providing both insulation and directivity in high voltage switching circuits. The SFJEL5000154MX0 series of feed through capacitors are ideal for a variety of applications, including control systems, high voltage pulse applications, and power inverters.

Cosmic\'s SFJEL5000154MX0 Capacitor Series Working Principle

The primary purpose of a feed through capacitor is twofold. Firstly, it can shield a circuit from the effects of interference, either from other electric components or from a mains supply. Secondly, the capacitor can provide impedance matching for certain levels of current. The SFJEL5000154MX0 utilizes the application of an electrostatic field to store and release energy in a highly efficient and reliable manner.The SFJEL5000154MX0 series is a surface mounted, low profile capacitor that consists of a cylindrical extruded base with two opposing electrodes. When AC voltage is applied, electrostatic forces between the two electrodes cause them to move apart, creating a uniform electric field within the unit. The energy stored in the electric field is proportional to the applied voltage, with the ability to withstand high levels of potential. The internal dielectric is an insulating material with high oxidation resistance and excellent temperature coefficient properties, providing excellent surge protection. The SFJEL5000154MX0 offers a variety of advantages over other types of feed through capacitors. Its low profile design allows for high density circuit board assembly, while its high dielectric strength ensures reliable performance in high voltage applications.

Application Fields

SFJEL5000154MX0 feed through capacitors are available in a wide range of capacitance values, making them ideal for a variety of applications. Common uses include electrical systems for motor vehicle control, direct current (DC) or alternating current (AC) power control, high voltage pulse applications, and power inverters. SFJEL5000154MX0 feed through capacitors offer several advantages over comparable capacitors. The design ensures high insulation performance when mounted to the circuit board, providing increased protection and miniaturization. The combination of high breakdown voltage and low leakage current makes them ideal for high voltage applications. The SFJEL5000154MX0 is also suitable for use in the telecommunications industry. Its low capacitance and high dielectric strength make it ideal for balancing the transmission impedance and bridging long cable runs to achieve consistent signal levels.

Conclusion

The SFJEL5000154MX0 series of feed through capacitors offer an ideal solution for a variety of applications, from motor vehicle control systems to high voltage pulse applications. Designed with a low profile and high dielectric strength, the SFJEL5000154MX0 provides superior insulation, reliable performance, and excellent surge protection for a wide range of demanding high voltage applications.
