Tantalum - Polymer Capacitors

T530X477M006ATE004 is one type of tantalum capacitors that offer a combination of ultra-small size, long-term reliability, a higher volumetric efficiency, and excellent electrical characteristics. The capacitor is constructed with tantalum powder as an anode which is chemically bonded to a manganese dioxide (MnO₂) cathode and enclosed in a non-conductive epoxy resin case.

Application Field

The T530X477M006ATE004 capacitor is well-suited for many electronic applications due to its size and electrical characteristics. It is commonly found in applications such as consumer electronics, automotive, telecommunications, and industrial equipment as it is capable of operating at temperatures ranging from -40 to +85°C. The capacitor is also specified for low impedance, high ripple current, and long term reliability for use in high frequency or high temperature applications.

Working Principle

T530X477M006ATE004 capacitors are formed on a tantalum pentoxide (Ta₂O₅) film which is dielectrically insulated from the cathode by a polysiloxane organic protective film. The electrical connection between the anode and the cathode is done through a thin layer of titanium dioxide (TiO₂). When a potential difference is applied across the capacitor, current flows through the dielectric film, thereby creating an electric field. This electric field induces a charge distribution between the plates. The current creates type of a Faraday effect, which is a phenomenon by which electric fields induce charge distribution in a dielectric material.

T530X477M006ATE004 capacitors are typically rated at 6.3V and can also be found in higher voltage ratings up to 10V. The capacitors are capable of cycling between -40C and +85C and possess higher ripple current capabilities and lower ESR (Equivalent Series Resistance). The tantalum capacitor also features a long shelf life and long working life, making it an especially reliable type of capacitor.

Conclusion

The T530X477M006ATE004 is a type of tantalum - polymer capacitors that offers several advantages over other types of capacitors. It is an especially usable size and offers a higher volumetric efficiency, long shelf and working life, and excellent electrical properties. The capacitor is suitable for many applications including consumer electronics, automotive, telecommunications, and industrial equipment. It is capable operating at an effective temperature range of -40C to +85C, and owing to its low ESR and high ripple current, is well suited to high frequency and high temperature applications.
