Tantalum - Polymer Capacitors are some of the most popular capacitors available on the market. They are known for having a low equivalent series resistance (ESR), high capacitance, and long life. The TCJA685M025R0150 is one of the most popular models in the Tantalum - Polymer Capacitor range. This article will discuss the application field and working principle of this capacitor.

Application Field

The TCJA685M025R0150 is ideal for high current power supply applications and switch-back power supply systems. It offers up to 850mA current without requiring additional heat sinking. The high capacitance and long life make this capacitor ideal for applications requiring high ripple currents and frequent switching cycles, such as audio amplifier power supplies. It is also suitable for power supply filtering and power factor correction.

The TCJA685M025R0150 is widely used in DC-DC converters, AC-DC converters, and DC fault protection circuits. It can also be used in automotive electronics, high frequency switches, and computer system power supplies. The capacitor is also suitable for a variety of other applications, including defibrillators and medical equipment.

Working Principle

A Tantalum - Polymer Capacitor consists of an anode and a cathode which are separated by an ionically conductive polymer film. The anode and cathode are made of tantalum powder, which makes the capacitor highly resistant to vibration and temperature changes. The polymer film acts as the dielectric and helps to store energy within the capacitor.

The TCJA685M025R0150 capacitor is a polymer-based capacitor that uses sintered anodes of tantalum pentoxide (Ta2O5). The anodes are sintered in vacuum, which reduces their size, increases their surface area, and increases their reactivity and performance. The cathode is formed by applying a thin layer of solid polymer to the anodes.

When a voltage is applied to the capacitor, the ions in the polymer film move in response to the electric field. This creates an electric double layer which stores the energy as electric field energy. The charge is stored on the anode and is discharged when the voltage is removed.

The TCJA685M025R0150 is a rugged, long-lasting capacitor that is resistant to shock and vibration, and reliable even in extreme temperatures. Its low equivalent series resistance provides high capacitance, allowing it to handle higher power levels in a smaller package. With its long life and high capacitance, it is the perfect choice for many applications.
