Tantalum - Polymer Capacitors

Tantalum-Polymer capacitors are a new class of high-performance power storage solution component that offers excellent electrical performance and reliability even in extremely harsh operating environments. In addition to offering excellent electrical performance, this component also offers a good form factor and the capability to operate over a wide temperature range. The primary application field for ETCF1000M6H is power electronics, where it is used to power automotive, aerospace, and industrial equipment.

Capacitor Construction

ETCF1000M6H tantalum-polymer capacitors are constructed from two layers; an interior solid electrolyte layer and an exterior solid polymer. Internally, the electrolyte layer is composed of thin anodized tantalum and a solid electrolyte composed of hydroxy-ethanol, and an oxide layer that serves to provide bulk capacitance. The exterior layer of the capacitor is then composed of a thin layer of solid polymer for mechanical, environmental, and electrical isolation. This structure ensures excellent electrical performance as well as a good form factor.

Operating Principle

The ETCF1000M6H capacitor operates based on the principle of electrochemical capacitance. In this case, the capacitor is charged and discharged by the exchange of ions between the solid electrolyte layer and the polymer exterior. This exchange of ions takes place at the electrical interface of the capacitor, and is known as Faradaic Charge Transfer. By alternating the voltage at the input, ions are either attracted or repelled from one side of the capacitor, and an electrical charge is stored in the capacitor as a result. This electrical charge can then be used to power an electrical load, or can be discharged over time to return to its original state, allowing for high performance and reliable power storage.

Performance Characteristics

The ETCF1000M6H tantalum-polymer capacitor offers excellent electrical performance, including low ESR and low ESL, as well as a wide temperature range of operation (-55C to +125C). The ETCF1000M6H also provides excellent electrical performance when used in pulse- power applications, with a current rating of 1000 mA and a voltage rating of 6 V. This makes the ETCF1000M6H an excellent choice for use in power electronics applications.

Conclusion

The ETCF1000M6H tantalum-polymer capacitor offers excellent electrical performance and reliability even in extremely harsh conditions. This makes it an ideal component for applications such as automotive, aerospace, and industrial equipment. Furthermore, the ETCF1000M6H offers a good form factor, wide temperature range of operation, and excellent electrical performance when used in pulse-power applications. Overall, the ETCF1000M6H tantalum-polymer capacitor is an excellent choice for power electronics applications due to its performance, reliability, and form-factor.
