Tantalum - Polymer Capacitors are applied in virtually all electrical and electronic industries, mainly to store electrical energy. The T551B127K050AT is a type of tantalum-polymer capacitor, which is a surface mount solid-electrolytic capacitor with a conducting polymer in the cathode. It has good reliability and can be stored at temperatures of up to 125°C, which makes the capacitor suitable for a wide range of applications. The capacitor is designed to provide superior performance in terms of high energy density, long lifetime, high temperature operation, and robustness against signs of wear and tear.

Working Principle

T551B127K050AT tantalum-polymer capacitors are based on an aluminum plate substrate covered with a special conducting polymer layer and a top layer of electrolyte. The combination of these materials creates a solid-electrolyte capacitor, where the electrolyte is the capacitor\'s dielectric and the surface of the capacitor\'s aluminum plate forms two separate electrodes between which a polarized electrical field is created. Thanks to this design, a dielectric voltage can be applied across the capacitor\'s surface, and the applied current is stored in the capacitor. The molecular structure of the polymer layer allows the electrons to flow in, out and across it, governing the capacitor\'s total capacitance.

The T551B127K050AT is a low-profile, temperature-resistant and high-performance capacitor, designed to handle an operating temperature range of -55 to +125°C and has a capacity of 1.6µF. Its low effective series resistance (ESR) is suitable for many high-value applications such as power supplies. The capacitor is also suitable for applications requiring long term stability with low self-discharge over temperatures, making it ideal for automotive and industrial applications. Furthermore, the T551B127K050AT is also very resistant to wear and tear and can handle up to 3,500 hours of lifetime.
