Tantalum capacitors have wide applications, from consumer electronics to life support systems. The TAP475M025GSB is a tantalum capacitor that is specifically designed for high temperature and space saving applications. This article will discuss the applications and working principle of the TAP475M025GSB.

Applications

The TAP475M025GSB is a tantalum capacitor that is commonly used in industrial and medical applications. It is designed with a high temperature endurance of up to 125°C and offers a wide temperature range of -55°C to +125°C. These characteristics make it an ideal choice for applications that require an extremely durable, space-saving capacitor that can perform in a variety of temperature conditions.

The TAP475M025GSB is also suitable for board mounting applications. It is designed with surface-mounted technology, which allows for a low profile design and easy installation on boards. It offers a high capacitance of 47µF, which makes it suitable for decoupling, smoothing, and energy storage applications. The TAP475M025GSB also features excellent stability, long life expectancy, and low leakage, making it ideal for high temperature and high reliability applications.

Working Principle

The TAP475M025GSB is a tantalum capacitor, which is composed of a tantalum anode and cathode, with a polymeric electrolyte between the two. The tantalum anode works as the negative electrode, and the cathode works as the positive electrode. The polymeric electrolyte is the material that allows current to flow between the two electrodes.

When voltage is applied to the TAP475M025GSB, current starts to flow and charges the capacitor. This charging process creates a separation of charge between the anode and cathode which results in an increase of the capacitor’s capacitance. Once the charging process is complete, the capacitor is said to be fully charged. When the voltage on the capacitor is removed, the capacitor will start to discharge, releasing the stored energy.

The TAP475M025GSB is designed with a temperature coefficient of ±15%/-55°C to +125°C, which ensures that the capacitor remains stable even when subjected to wide temperature swings. It is also designed with a very low impedance (ESR), which allows the capacitor to quickly and reliably discharge energy when necessary. This low impedance also ensures that the capacitor will not dissipate energy in the form of heat as it discharges.

Conclusion

The TAP475M025GSB is a high temperature, space saving tantalum capacitor that is well suited for use in industrial and medical applications. It is designed with a high temperature tolerance of up to 125°C and offers a wide temperature range of -55°C to +125°C. It features a high capacitance of 47µF, excellent stability, and long life expectancy. The low impedance (ESR) ensures reliable energy storage and discharge. The TAP475M025GSB’s robust design and stable performance makes it ideal for high temperature and high reliability applications.
