Feed Through Capacitors (FTCs) are widely used in many industrial, medical, and consumer applications. The PSM4-101M-02B is a member of this family, a surface-mount, single-layer Low Frequency Feed Through Capacitor. It is one of the smallest packages in its class.

The application fields of the PSM4-101M-02B are diverse. The low profile makes this part particularly suitable for use in space-restricted areas, while its surface-mount construction enables easy installation. Additionally, its construction makes it well-suited for high-density, high-performance systems. In particular, these touch-and-go capacitors are ideal for use in audio, video, and power supply applications, such as LCD display and cellular phone amplifiers, as well as RF power amplifier circuit designs.

The working principle of the PSM4-101M-02B is based on a dielectric constant that gives it a high capacitance. This capacitance helps the device to reduce the amount of noise produced by the electri-coupling, while also providing a relatively low ESR (equivalent series resistance) that enables greater current handling capability. Inside, the device contains two opposing, tin-plated electrodes that are connected to the customers’ existing power supply, shield, or reference voltage. The electrodes are separated by an insulating material, allowing the applied voltage to pass through the capacitor.

This capacitance is designed to filter out unwanted RF interference, while also providing protection from voltage and current fluctuations. Furthermore, the device is rated for both pulse withstanding and static discharge capabilities, making it highly durable and reliable. The overall lifetime of the product is also enhanced by a special layer of coating on the electrodes that provides superior corrosion and oxidation resistance.

The final result is a feed through capacitor with great performance characteristics in terms of high capacitance, high current handling capability, high ESR, reliable pulse withstanding and static discharge capability, and corrosion and oxidation resistance. All these characteristics make the PSM4-101M-02B an excellent choice for modern industrial, medical, and consumer applications.
