Tantalum capacitors are highly reliable and energy-efficient components that are widely used in a variety of electronic systems and products. This article looks at the application field and working principles of the TH3B225K025C3000, one of the most popular capacitors in its manufacturing market.

Capacitors play an important role in the power supply design of electronic equipment and systems, providing short-term energy storage as well as high frequency noise filtering. Tantalum capacitors, specifically, are ideal for designing low voltage power supplies, DC-DC converters, snubbers, and PWM circuits, due to their high tolerance to ripple current and extremely low equivalent series resistance (ESR).

The TH3B225K025C3000 model of tantalum capacitor is widely used in the telecommunications, industrial automation, GPS, art lighting, and medical markets today. It has a rated temperature range of -55 to +125°C and is available with EIA case sizes from B case to T case. It also provides excellent frequency and temperature characteristics, with a subset of products offering a voltage of 450V and a capacitance of up to 2,200μF.

To understand how this capacitor works, it is important to understand the key concepts of capacitance and capacitive reactance. Capacitance is the amount of charge stored in the capacitor, expressed in farads, which can supply current when called upon. Capacitive reactance on the other hand, is the opposition the capacitor offers to AC voltage and current. Reactance is determined by dividing the frequency of the voltage applied by the capacitance of the capacitor, and is expressed in Ohms.

So, how does the TH3B225K025C3000 work? In this model of capacitor, the charge is distributed between two porous titanium electrodes, which are connected by a dielectric medium, typically tantalum pentoxide. When a voltage is applied in this model of capacitor, the charges on the electrodes flow from one to the other and capacitive reactance is formed. The unique properties of the titanium electrodes allow for a higher volumetric efficiency, making the TH3B225K025C3000 capacitor one of the smallest industry solutions for high voltage, high capacitance applications.

The TH3B225K025C3000 has proven to be a reliable component in power supply design applications. It offers excellent high frequency characteristics, provides high tolerance to ripple current, and offers low Equivalent Series Resistance (ESR) values. With its rated temperature range of -55 to +125°C and EIA case sizes ranging from B to T, this component is the ideal choice for demanding applications across a variety of industries.
