NFM21PC105F1C3D is one of the feed through capacitors (FTCAP) produced by TDK, which is widely used in many electronic devices. They are typically used in applications where a single point of contact needs to be made between two dissimilar electrical potentials in order to reduce electrical noise, maintain safe electrical insulation, or prevent dangerous power surges.

FTCAPs are characterized by their ability to pass an electrical signal through from one side of the capacitor to the other while remaining electrically insulated so that each side is isolated from the other. This is achieved using a special dielectric material between two conductive plates. The dielectric material used is usually an insulation material such as polyethylene, polycarbonate, or polypropylene.

The NFM21PC105F1C3D is a low profile capacitor that is designed to pass AC and DC signals up to 1 GHz and is commonly used in radio frequency (RF) circuits to reduce noise and improve signal integrity. It features a high dielectric strength of 750VAC, an insulation resistance of 500 MΩ, and a capacitance range of 0.1 to 10 pF. The capacitor is available in several different voltage ratings and package sizes, making it suitable for a wide range of applications.

NFM21PC105F1C3D capacitors are used in a variety of applications, including RF and microwave communications, television transmitters and receivers, audio amplifiers, industrial automation, and medical devices. They also find use in automotive, computer, and telecommunications systems. They provide isolation between two circuits carrying RF energy, which helps reduce noise and save energy by preventing power surges between the two circuits.

The working principle of a feed through capacitor is based on the idea of using an electrical current to create an electrical field between two opposite conducting plates. As electrical current flows through the plates, an electric field is created between them that separates the two conducting plates and helps keep them electrically isolated from each other. The electric field also helps reduce noise since it attenuates any signals that pass between the two conducting plates. This makes FTCAPs ideal for applications where electrical noise reduction is a priority.

Overall, NFM21PC105F1C3D is an excellent feed through capacitor that offers a wide range of capabilities for a variety of applications. It is a reliable and efficient capacitor that is easy to install in a variety of environments. Its high dielectric strength and insulation resistance makes it suitable for use in RF and microwave communications. Its low profile design also allows it to be used in tight spaces. It is an ideal component for design engineers looking to reduce electrical noise or improve signal integrity.
