Tantalum - Polymer Capacitors

Tantalum - Polymer capacitors are useful components that have found applications in a variety of industries, including automotive, military, aerospace, and medical. The T540D477M003DH8505 is one such component that has a variety of applications and working principles. Tantalum - Polymer capacitors are characterized by their high capacitance per voltage rating (CV). These capacitors are available in both surface mount and through-hole versions and have excellent long-term reliability and robustness. They are also immune to shocks, vibration and sudden cycling, making them ideal for applications that require high reliability. The T540D477M003DH8505 is a surface mount, two-terminal tantalum - polymer capacitor. It has 15 VDC rated voltage and 4.7 mF capacitance and offers excellent specific capacitance performance, with a CV of 3.2 x 10⁷ µF/V. This makes it a versatile capacitor that can handle a wide range of applications, ranging from low-current bypass and decoupling to high voltage power conversion. The T540D477M003DH8505 is designed for stable operation at temperatures of up to 85 degrees Celsius. It has an ESR rating of <50mΩ, making it an ideal choice for applications where low ESR is necessary. The capacitor is constructed with an anode formed from a polymer material that is both flexible and resilient, preventing it from cracking under stress and vibration. The capacitor also has excellent self-healing properties, which make it well-suited for applications where frequent power cycling is required.In terms of its application field, the T540D477M003DH8505 is commonly used in power supplies, such as those used in personal computers, server systems, and other high-performance devices.
