Feed Through Capacitors are used in electronic circuits for various applications. PSM4-102M-02B is a type of feed through capacitor typically used for signal filtering and EMI suppression. This type of capacitor has an operating voltage of 16V and a rated capacitance of 1.5uF.

The construction of the PSM4-102M-02B can be broken down into three parts. The first part is the capacitor\'s dielectric or plates, which are made of materials with high-dielectric constants such as ceramic or polyester. The plates are covered by a metal shield to protect them from external electrical interference. The second part is the capacitor\'s terminals, which consists of a pair of copper leads that attach to the plates. The third part is the capacitor\'s body, which can be made of either ceramic, plastic, or metal, depending on the application.

The main functionality of feed through capacitors such as the PSM4-102M-02B is to filter signals by blocking high frequencies while allowing lower frequencies and DC current to pass. This is accomplished by the capacitor\'s ability to store electrical charge. When a signal is applied to the capacitor, the capacitor stores some of the energy from the signal, while the remaining energy passes through the capacitor. The amount of energy stored by the capacitor is determined by the capacitance value. The higher the capacitance, the more energy is stored by the capacitor.

The PSM4-102M-02B is most commonly used in RF applications such as in radio receivers and transmitters. The capacitor reduces the amount of radio frequency (RF) noise that enters or leaves the system by blocking high frequency signals while allowing low frequency signals to pass. It is also used in high-frequency electronic circuits where it helps to minimize interference and reduce crosstalk between neighboring circuits. Additionally, the capacitor can be used for EMI suppression. By blocking frequencies that can cause interference with nearby systems, the capacitor improves overall signal integrity.

In addition to its RF and EMI suppression applications, the PSM4-102M-02B can be used for energy storage. As the capacitor stores electrical energy, it can be used to supply a continuous, limited amount of power to a circuit. This is especially useful for applications such as DC-DC converters, AC-DC converters, and DC-AC inverters, where a constant supply of power is needed.

In conclusion, the PSM4-102M-02B is a feed through capacitor that is commonly used for filtering, EMI suppression, and energy storage applications. It has a capacitance value of 1.5uF and can operate at up to 16V. The capacitance of the capacitor determines how much energy is stored, and the type of material used in its construction determines its overall electrical characteristics. The PSM4-102M-02B is well-suited for RF applications, high-frequency electronic circuits, and for providing a steady supply of energy to a circuit.
