Tantalum-polymer capacitors are a type of electrolytic capacitor, made from a metallic tantalum anode with a porous oxide surface, and a high-temperature version of the organic polymer material, Polyethylene Oxide, as the cathode. The Tantalum-polymer capacitors offer very high capacitance, long life and reliable continuous operating temperature of 125C.

The T540D227K006AH8705 is a particularly attractive, low-cost answer for high performance applications in mobile phones and other portable electronics. It features an ESR of 6.25, an EMI of 25K, and a DC Leakage Current of 9.25µA. It also works well in automotive and power supply applications.

The T540D227K006AH8705 offers a wide operating temperature range of -55C to +85C, with a stable capacitance across a wide temperature and voltage range. Unlike other polymer caps, the T540D227K006AH8705 has excellent thermal characteristics, being able to dissipate power in a controlled manner at a faster rate than Aluminum-electrolytic caps.

When compared to an electrochemical capacitor, the T540D227K006AH8705 has a much faster charging cycle, which means it can store more energy and thus deliver more power at a faster rate. This makes them ideal for high speed applications and for dealing with short-term bursts of power. Additionally, the T540D227K006AH8705 also offers extended service life, with an extremely low self-discharge rate, even with a prolonged storage period.

The working principle of the T540D227K006AH8705 can be attributed to its unique construction. The combination of the metallic tantalum anode and the high-temperature, Polyethylene Oxide material, forms a porous oxide surface which when exposed to an electric voltage, allows the diffusion of ions to take place. This diffusion creates an electric field, allowing charge carriers to move within the electrolyte and produce an electrochemical reaction.

The reaction that occurs is a redox reaction, meaning that when the anode is oxidized, it releases electrons to the cathode, where they are converted into ions. The positive ions are then attracted to the anode, and the electrons are attracted to the cathode, resulting in a current flow in the opposite direction. This results in the generation of electrostatic charge, which is stored in the capacitor.

The T540D227K006AH8705 is a low-cost alternative for high performance applications such as mobile phones and other portable electronics, automotive, and power supply applications. Its wide operating temperature range and stable capacitance make it ideal for applications requiring short-term bursts of power, and its long life and low self-discharge rate ensure reliable operation. Its unique construction allows it to deliver charge carriers more quickly than traditional electrolytic capacitors, making it a great choice for high speed applications.
