Introduction to Tantalum - Polymer Capacitors
Tantalum - Polymer capacitors (or Ta- polymer capacitors) are a type of solid electrolyte capacitor that offers higher capacitance and longer life than their traditional counterparts such as tantalum capacitors. They are typically used in applications that require a high capacitance to mass ratio such as mobile phones, digital cameras, personal computers and automotive electronics.

T540D227K004DH8605WAFL
The T540D227K004DH8605WAFL is a Tantalum Polymer Capacitor from Vishay’s PowerCap® family that provides a low ESR and low temperature coefficient. It has a capacitance of 22uF, a rated voltage of 6.3V, and a tolerance level of ±20%. The T540D227K004DH8605WAFL is designed for use in a range of automotive, portable, and consumer electronics applications.

Application Fields
The T540D227K004DH8605WAFL is an ideal choice for applications in the automotive and consumer electronics segments that require a higher capacitance to mass ratio including:

  • Bluetooth devices
  • Portable gaming consoles
  • MP3 players
  • GPS systems
  • Audio amplifiers
  • Portable medical devices
  • Car video systems

The T540D227K004DH8605WAFL is also a good choice for military and aerospace applications due to its wide temperature range and high reliability.

Working Principle
Tantalum - polymer capacitors use a solid polymer electrolyte in combination with an anodized thin film of tantalum. The anodized thin film of tantalum is used as the electrode and the solid polymer electrolyte is used as the dielectric material. This combination of anodized tantalum and solid polymer electrolyte enables the capacitor to have higher capacitance values, lower leakage current and better temperature stability than traditional capacitors.

As electricity is applied to the capacitor, charge is stored in the capacitor’s electrodes. The stored energy then discharges during the low-voltage part of the circuit’s cycle, allowing the capacitor to provide energy to the system. As the capacitor’s electrodes discharge, the electrons pass through the electrolyte, providing a path for the charge to move through. The electrolyte acts as a medium for the electrons to travel from one electrode to the other, creating a current in the process.

Conclusion
The T540D227K004DH8605WAFL is an excellent choice for automotive, portable and consumer electronics applications due to its high capacitance-to-mass ratio, low ESR and excellent temperature coefficient. It is also a viable choice for military and aerospace applications due to its wide temperature range and high reliability. The capacitor’s working principle relies on anodized tantalum electrodes and a solid polymer electrolyte that allows electrons to travel from one electrode to the other, creating a current in the process.
