Tantalum – Polymer CapacitorsA tantalum – polymer capacitor is an electronic component designed to store and regulate electricity. They are made of a tantalum anode and an electrolytic polymer dielectric filled with an electrolyte. The capacitor stores electrical energy in a non-linear dielectric material that is used between two plates separated by an insulating capacitor material. The purpose of capacitors is to regulate voltage levels or provide isolation from electrical noise.The specific Tantalum – Polymer capacitor T540D687K2R5BH87057280 is a Molded D capped radial leaded equipment grade solid polymer capacitor specifically designed for applications where high temperature, long life and high capacitance density are required. It is a wet tantalum polymer capacitor with a cylindrical sleeve shape and radial leads.This capacitor is equipped with a high capacitance density and designed with a small size. It offers rated capacitance ranging from 0.1 uF to 1000 uF and can operate at temperatures of up to 130°C. It also has positive temperature coefficient capability sparing to make a voltage adjustable capacitor. This T540D687K2R5BH87057280 has a maximum voltage rating at 4 Volts and it is feedback suitable, UL approved and compliant with the RoHS Directives.The tantalum-polymer capacitors are mainly used in applications where the standard aluminum electrolytic capacitors don’t perform well due to their temperature instability, limited life, and high ESL values. Some of the common applications for these capacitors are as follows:• High temperature and high ripple current power supplies• Pulsed power systems• Power amplifiers• Audio amplifiers• Noise canceling• High frequency amplifiersThe working principle of a tantalum-polymer capacitor is relatively simple. The anode and cathode of the capacitor are connected to two plates, and the electrolytic polymer dielectric between the plates is filled with an electrolyte. An electric field is created when a voltage is applied to the plates, allowing electrons to flow through the capacitor, charging it up and allowing it to store energy. The amount of energy the capacitor can store depends on the size and type of the capacitor and the amount of voltage applied to it.In conclusion, the T540D687K2R5BH87057280 is a reliable, high temperature, solid polymer capacitor with a radial configuration and maximum voltage rating of 4 Volts. It is suitable for applications that require high capacitance density and high temperature stability. It is UL approved and RoHS compliant and can be used in pulsed power systems, audio amplifiers and noise canceling circuits.
