Feed through capacitors are electronic components that act as capacitance between incoming and outgoing power circuits. The NFM21HC104R1A3D is a very common feed through capacitor, used in a wide variety of applications. This component is excellent for blocking DC power from entering a circuit, while allowing AC power to pass through. In this article, we will discuss the application field and working principle of the NFM21HC104R1A3D.

Application Field

The NFM21HC104R1A3D feed through capacitor is often used in telecommunications, medical equipment, and other sensitive applications where high-frequency noise must be blocked from entering the circuit. This component helps to prevent electrical interference between various devices when they are connected together. In addition, the NFM21HC104R1A3D is also used for EMI filtering, which helps to reduce the amount of electrical noise emitted by a device.

This feed through capacitor is also popular in solar energy systems. It is used in the system’s power inverter, where it helps to reduce the amount of EMI generated by the inverter. In addition, the component is used in medical equipment to provide protection against potential electric shocks or faulty wiring. It can also be used to improve the signal clarity in audio and video applications.

Working Principle

The NFM21HC104R1A3D feed through capacitor works in a similar manner to that of other feed through capacitors. This component is designed with two electrodes, which create a parallel path between two circuits. Incoming high-frequency signals are blocked from entering the circuit, while low-frequency signals are allowed to pass through. The component has an insulation layer between the two electrodes, which helps to prevent any high voltage or current from leaking into the circuit.

The NFM21HC104R1A3D is also designed with a small air gap between the two electrodes. This helps to increase the capacitance of the component, resulting in a better signal transmission. In addition, the component is designed with an internal temperature protection system, which prevents it from overheating during use. This is especially important in sensitive applications where heat build-up could cause permanent damage to the component.

Conclusion

The NFM21HC104R1A3D feed through capacitor is an excellent choice for EMI filtering, noise suppression, and voltage protection. This component is widely used in telecoms, medical equipment, and solar energy systems. Its effective two-electrode design blocks high-frequency signals, while allowing low-frequency signals to pass through. In addition, the NFM21HC104R1A3D is designed with an internal temperature protection system, which helps to prevent it from overheating during use.
