Tantalum capacitors are members of the larger capacitor family which also includes tantalum polymer capacitors. By replacing the liquid electrolyte with a plastic solid polymer, the tantalum-polymer capacitor gains advantages in size, temperature stability and leakage current. The T550B256K100AH4252 is a part of a larger series of tantalum-polymer capacitors that share specific characteristics and applications.

Application Field

The T550B256K100AH4252 is mainly used in the fields of industrial and automotive electronics, where it is subject to severe shock and vibration. It has a lifetime of 4500 hours of operation at 85 degrees Celsius and 10,000 hours of operation at 125 degrees Celsius. It can withstand a voltage ranging from 6.3V to 10V and comes equipped with a low maximum ESR of 0.02 ohms. Thanks to its unique polymer electrolyte, the capacitor has a good operating temperature range from -55 to +125 degrees Celsius. Additionally, it has the capability of withstanding overvoltage better than traditional capacitors.

Working Principle

The working principle of the T550B256K100AH4252 is based on the same principles as that of any other tantalum capacitor. An electrical conductor is surrounded by a dielectric material and placed between two capacitive plates. When a voltage is applied to the capacitor, electric charge accumulates at the two plates, resulting in an electrical field. This field stores potential energy and acts as a power reserve.

The unique characteristic of the T550B256K100AH4252 lies in its polymer electrolyte instead of the conventional liquid electrolyte. The polymer electrolyte can provide greater volumetric efficiency which in turn reduces the size of the capacitors. In comparison to tantalum capacitors, the T550B256K100AH4252 has superior temperature stability, superior leakage current and improved capacitance over time. The good performance in withstanding voltage and currents makes them suitable for use in high reliability applications.

Conclusion

The T550B256K100AH4252 is a type of tantalum-polymer capacitor characterized by its small size, temperature capability and low leakage current. It is mainly applied in industrial and automotive electronics and provides good performance in withstanding voltages and currents. Its unique polymer electrolyte renders the capacitors with superior volumetric efficiency and improved capacitance characteristics over time. Thus, the popularity of the T550B256K100AH4252 amongst many applications is propelled by its superior performance and reliable service.
