It is an excellent choice for military and aerospace applications since it is able to support a wide operating temperature and is highly resistant to shock and vibration.

Working Principle

Tantalum-polymer capacitors function by using a thin, solid layer of semiconductive organic polymer which serves as the dielectric material. This thin polymer layer is sandwiched between two thin metallic foils and serves as the electrical insulator, separating the positive and negative internal plates. During operation, electricity traveling from the positive end to the negative end of the device is limited by the dielectric material. As the capacitor operates, a high value electric charge is stored between the internal plates.

The T540D477K2R5CH8505WAFL is designed with a low Equivalent Series Resistance (ESR) and long-term stability. The combination of an efficient power supply with the low ESR ensures that the device is more reliable and efficient when powering circuits with high-frequency waveforms. Additionally, the low ESR reduces power losses when used in DC/DC Converters, yielding a more efficient and reliable power supply.
