Tantalum-Polymer Capacitors extend the capabilities and advantages of traditional tantalum capacitors, enabling them to be used in applications that were previously impossible due to their form factor and characteristics. The 4TPE220MI capacitor is designed specifically for use in applications with high temperatures and voltage.

Application Field

The 4TPE220MI capacitor is a tantalum-polymer capacitance product produced by the Elec Power Corporation. It is suitable for high-temperature and high-voltage applications. It is rated for operating temperatures up to 105°C and is capable of withstanding voltage ratings up to 22V. This makes it ideal for harsh environments and applications that require high temperature and high voltage components. It is commonly used in automotive electronics, HVAC systems, telecommunications, power supplies, automotive safety systems, and many other industries.

Working Principle

The 4TPE220MI capacitor is a tantalum-polymer capacitance product with a solid polymer cathode and an anode foiled design. It is designed to function even at high temperatures, since the polymer cathode material can withstand temperatures of up to 200°C. The anode foiled design ensures reliable conductivity in the presence of moisture and other elements. The capacitance value of this capacitor is 220 micro-Farads. The capacitor also has a low equivalent series resistance of 0.02 Ohms, making it suitable for high-current applications.

Advantages

The 4TPE220MI capacitor has many advantages over traditional tantalum capacitors. The first is its high temperature and voltage ratings, which make it ideal for applications requiring high performance in extreme temperatures. Additionally, the capacitance value of 220 micro-Farads makes it suitable for handling large amounts of current. Finally, its low equivalent series resistance ensures reliable current handling and high reliability in extreme conditions.

Disadvantages

The only significant disadvantage of the 4TPE220MI capacitor is its relatively high cost. While it is more expensive than traditional tantalum capacitors, its performance at higher temperatures and voltages makes it worth the extra cost for many applications. Additionally, due to its high temperature rating, it must be mounted properly in order to prevent over-heating, which could lead to catastrophic failures.

Conclusion

The 4TPE220MI capacitor is a reliable and high-performance tantalum-polymer capacitance product. It is rated for operating temperatures up to 105°C and is capable of withstanding voltage ratings up to 22V, making it suitable for demanding applications and high temperatures. The 220 micro-Farads of capacitance, low equivalent series resistance, and long-term reliability make it ideal for a range of applications, although it will cost more than traditional capacitors.
