Conductive Polymer Aluminum Solid Capacitors

Solid capacitors are the most high-end capacitors except tantalum capacitors. They are made of highly conductive molecular materials with powdered electrolytes inside. They have the advantages of explosion-proof slurry, good stability, high reliability, high temperature resistance, and long life. The main function of solid capacitors is to further filter some current spikes and clutter, ensuring the stability of power supply to various parts.

Tantalum Polymer Capacitor

A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits. It consists of a pellet of porous tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode. Because of its very thin and relatively high permittivity dielectric layer, the tantalum capacitor distinguishes itself from other conventional and electrolytic capacitors in having high capacitance per volume (high volumetric efficiency) and lower weight.

High voltage rectifier is a single-junction diode, which blocks the required voltage quickly without leaking reverse current, or generating heat from power losses in the process. However in reality, high-voltage rectifiers offer complex trade-offs.

A3PS-C

TVS, called transient voltage suppressor, is divided into unidirectional and bidirectional. Unidirectional TVS is mainly used in DC circuits, and bidirectional TVS is used in AC circuits. The TVS application is anti-parallel in the circuit. When the circuit works normally, it is in the cut-off state (high impedance state), which does not affect the normal operation of the circuit. When an abnormal overvoltage occurs in the circuit and reaches its breakdown voltage VB, it quickly changes from a high resistance state to a low resistance state, absorbs and discharges the overcurrent generated by the abnormal overvoltage to the ground, and clamps the abnormal overvoltage at the same time. Within the safe range that the first-stage circuit can withstand, so as to protect the subsequent-stage circuit from being damaged by abnormal overvoltage. When the abnormal overvoltage disappears, the resistance of the TVS returns to the original high resistance state.

The Schottky diode also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action. The cat's-whisker detectors used in the early days of wireless and metal rectifiers used in early power applications can be considered primitive Schottky diodes.
When sufficient forward voltage is applied, a current flows in the forward direction. A silicon p–n diode has a typical forward voltage of 600–700 mV, while the Schottky's forward voltage is 150–450 mV. This lower forward voltage requirement allows higher switching speeds and better system efficiency.
