Tantalum capacitors are among the most convenient and reliable surface mount components for use in a variety of applications. The TARR685K010, in particular, is a solid, electrolytic capacitor with a tantalum cathode that has been developed for usage within extreme environment applications due to its design that guarantees a high-performance with robustness and longevity

The TARR685K010 has a polyester (PET) dielectric that is coated with a wet tantalum/pentoxide layer, giving the capacitor outstanding reliability and stability under both high-temperature and lower temperature applications. The PET dielectric provides both a great electrical-mechanical stability and insulation properties over a broad temperature range. This dielectric is also able to provide an outstanding capacitance stability over temperature range from -55°C to +85°C making this capacitor ideal for use in applications where there will be wide-ranging temperature fluctuations.

The TARR685K010 also has a low-ESL allowing high self-resonance frequency at low temperatures, and with its low-profile design, it can also fit in the tightest spaces too. This capacitor also has a high ripple current rating, making it suitable for applications in which high power levels are necessary. Additionally, its capacitance value is retained to within ±20% -25ºC to 85ºC making it compatible with a variety of arduous applications.

The working principle of the TARR685K010 is based upon the theory of electrostatics. The capacitor consists of two metallic plates that are separated by an insulating material or dielectric. A voltage applied to the capacitor causes a current to flow through the dielectric, picking up charge. This charge is stored on both the positive and negative plates and creates a static electric field that maintains the voltage applied. When the voltage is removed, the electric field begins to decay, and the plates start to lose their charge, causing a current to flow again in the opposite direction.

The TARR685K010 is predominantly targeted towards a range of extreme environment applications including Automotive, Telecoms, ITE, and Industrial. The design of this capacitor also means that it can be used in extreme temperature applications, offering reliability, robustness, and a high-performance even in the toughest of environments.

To conclude, the TARR685K010 offers excellent performance and reliability when used in applications that require consistent performance with the added advantage of being able to operate in both high and low temperature ranges. With its low profile design, excellent self-resonance frequency, and high ripple current rating, this tantalum capacitor is an ideal choice for robustness and endurance in extreme environment applications.
