Tantalum Capacitors

Tantalum capacitors are an electric double-layer capacitor with a tantalum anode and a liquid electrolyte. They are also called tantalum electrolytic capacitors and are widely used in most electronic circuits due to their relatively small size, low cost, and high stability. Additionaly, they operate below a wide temperature range and offer good high frequency performance. They are also frequently used in power supplies, audio circuits, motor control circuits, and more.

TR3E686K020C0150 Application Field and Working Principle

The TR3E686K020C0150 is a certain type of tantalum capacitor. It has a capacitance of 6.8mF and is rated at 2.5V DC. Its ripple current rating (100kHz) is 0.262A and its ESR is 2.5 mΩ (at 25℃). This capacitor is mainly used in power electronic converters, such as SMPS, PFC, and BLDC motor controllers, which require a strong ripple current capability. This capacitor has excellent long-term reliability and stability, especially when used under high temperature and high voltage cycles.

The working principle of the TR3E686K020C0150 is similar to that of other electrolytic capacitors. It uses an anode made of sintered tantalum and a cathode made of liquid electrolyte. The two electrodes are separated by a dielectric material, and when a voltage is applied between them, an electric field is generated, which creates the electrical energy the capacitor can store. The capacitor stores electric energy by charging and discharging to maintain a certain voltage, which is why it is commonly known as a “charge storage” capacitor. The dielectric material used in this capacitor is usually a solid electrolyte, which helps improve its durability and reliability.

When using a TR3E686K020C0150, it is important to keep in mind that its performance may vary slightly due to its temperature coefficient. The nominal voltage of this capacitor is 2.5V DC, but its real working voltage is typically around 2V DC. Also, it is important to use a series resistor (usually 1 to 10kΩ) together with it when used to filter DC current. This will help to reduce internal heat and prevent the capacitor from failing.

Overall, the TR3E686K020C0150 is a reliable and efficient type of tantalum capacitor. It offers a wide range of voltage, current, and frequency ratings, and its excellent long-term reliability makes it a great choice for many types of electronic circuits.
