Tantalum - Polymer Capacitors

T543X337M016AHW0257505 is an application field and working principle of tantalum - polymer capacitors. A tantalum - polymer capacitor is an electrochemical device and part of the Solid Tantalum Electronic Components family. This type of capacitor has a monolithic anode/ cathode construction and a polymer electrolyte. It is ideal for applications that require high voltage, high capacitance, and low ESR capacitors in a small size package.

How does a tantalum - polymer capacitor work?

A tantalum - polymer capacitor consists of three components: an anode, a cathode and a separator. The anode is typically made from tantalum foil and powder, which is sintered with manganese dioxide. The cathode is made of a dielectric polymer usually polypropylene, polycarbonate or polyethylene oxide. And the separator is an electrolyte made from polyethylene oxide.When a voltage is applied across the capacitor, a positive charge gathers on the anode and a negative charge gathers on the cathode. This creates an electric field that eliminates both electrodes, and the electrolyte solutions acts as an insulator, preventing a direct current. The electric field between the anode and the cathode generates the capacitance, which is measured in Farads (F).

Benefits of tantalum - polymer capacitors

Tantalum - polymer capacitors have a number of advantages over traditional electrolytic capacitors. The most notable benefit of these capacitors is their superior size and weight; they are much smaller and lighter than electrolytic capacitors, making them ideal for applications where size and weight are an issue.The second benefit of tantalum - polymer capacitors is their high temperature capability, withstanding temperatures up to +125°C for extended periods without any loss in capacitance. This makes them suitable for long life applications.The third major benefit of tantalum - polymer capacitors is their high ripple capability. These types of capacitors can handle high frequency ripple, which makes them ideal for voltage converter applications.Finally, tantalum - polymer capacitors have a low ESR, which makes them ideal for handling harmonic applications,. This is especially useful in power factor correction applications.

Applications

Tantalum - polymer capacitors are typically used in three main applications:Medical: These capacitors are ideal for medical applications, where their small size and low ESR components make them ideal for implantable and external medical devices.Automotive: In automotive applications, their high temperature capability and low ESR components make them an ideal choice for powertrain and engine control modules.Power: The high ripple capability and low ESR is ideal for voltage converter and power factor correction applications.

Conclusion

Tantalum - polymer capacitors are an advanced electrochemical device and part of the Solid Tantalum Electronic Components family. These capacitors have a monolithic anode/cathode construction and a polymer electrolyte. They are ideal for applications that require high voltage, high capacitance, low ESR capacitors in a small size package. The major benefits of tantalum - polymer capacitors include their superior size and weight, high temperature capability, high ripple capability and low ESR. These types of capacitors are typically used in medical, automotive and power applications.
