T540D687M003BH87057280 is a type of tantalum - polymer capacitor, a device used to store and manage electrical energy in various types of electronic circuits. Also known as Wet Tantalum capacitors, these components become increasingly popular due to their small footprint and high energy density. The T540D687M003BH87057280 type of tantalum capacitor is a supercapacitor that provides low ESR, high ripple current and high temperature performance.

Application

Tantalum - polymer capacitors are found in a variety of electrical and electronic applications, including:

  • Power supplies & charging systems
  • Data converters
  • Power management circuits
  • Processor circuits
  • High-speed digital circuits
  • RF & microwave amplifier circuits
  • Power amplifiers
  • Switched-mode power supplies

The T540D687M003BH87057280 capacitor is specially designed for use in high-efficiency, high-current, high-frequency applications. It is widely used in servers, datacom, computing and other industrial applications.

Working Principle

Tantalum - polymer capacitors are non-polarized capacitors that use tantalum oxide (or Ta2O5) as the dielectric material. They consist of two carbon powder-filled anode electrodes on either side of the dielectric material, with a thin layer of electrolyte-filled polymer isolating the electrodes. The electrical charge accumulates on the anode electrodes while the dielectric material keeps the charge from leaking. The high dielectric constant of the tantalum oxide material enables the device to store energy reliably.

The physical size of the capacitor is filled to create the electrode contact area, the dielectric material is operated at high temperatures and low voltages, and the electrolyte is maintained at a constant temperature to moderate the capacitor\'s characteristics. The T540D687M003BH87057280 also incorporates a wire-bonded or face-down anode configuration to reduce inductance and its associated losses, while offering a wide capacitance range.

The performance of these tantalum - polymer capacitors is very stable and reliable, with high maximum ripple current rating and a steady capacitance over a wide frequency range. They feature low ESR, low tolerance, long life and high temperature operation up to 125°C. These benefits make the T540D687M003BH87057280 capacitor an ideal choice for high-density power designs.
