Introduction of T540D477K004BH8510WAFL Capacitors T540D477K004BH8510WAFL capacitors are among the cascade of medium to high voltage surface-mount tantalum capacitors (first introduced in the 1950s) with a polymer base (also often termed “tantalum-polymer”). These capacitors feature a very low equivalent-series-resistance (ESR) and very low failure rate, and are available in a variety of sizes and configurations. They are used for a variety of applications, including Low-ESR capacitors for dc-to-dc converters, load capacitors for switching power supplies, and pseudo-capacitors for high-current applications.Application Fields of T540D477K004BH8510WAFL Tantalum capacitors are used for a myriad of applications and provide distinct benefits over other types of capacitor technology. They are able to provide higher capacitance in a minimal form factor, while also exhibiting a very low ESR, making them suitable for many switch mode power supplies, as well as battery-powered applications, and to provide improved filtering performance. The main applications of T540D477K004BH8510WAFL capacitors vary with the operating voltage and quality requirements, but are mostly used in the following fields:

• DC-DC converters
• Switching power supplies
• Notebook computers
• LCD monitors
• Computer servers
• Cell phones
• High voltage dc/dc converters
• LED lighting
• Medical applications
• Automotive applications

Working Principle Tantalum capacitors are constructed from an anode, a cathode, and an electrolytic material. The anode is comprised of a sintered tantalum metal powder combined with binder material while the cathode is typically a metallic foil that acts as a current collector. Between these two components, a dielectric material called “polymer” is inserted. This polymer is an organic substance that serves to reduce the capacitance leakage in the capacitor. When used in electronic circuits, an electric current passes through the anode and the cathode, creating an electrostatic field. This field stores energy within the capacitor, using the anode and the cathode as its two plates. By regulation of the current, the magnitude of the electrostatic field can be easily adjusted and changed. T540D477K004BH8510WAFL capacitors also feature very low ESR and very low electrical dissipation factors due to their use of a polymer-based dielectric material. This material provides better electrical isolation from the anode to the cathode, which results in improved circuit current handling ability. They are also capable of reliably handling high temperature operating environments, thanks to their high operating temperature range up to 125°C. T540D477K004BH8510WAFL capacitors are popularly used in many applications because of their flexibility and cost-effectiveness. They have become an increasingly exceptional alternative among medium to high voltage capacitors in the market. They are reliable and are able to perform well in various electronic circuits due to their capability to stay robust in a wide temperature range.
