Tantalum Capacitors

TPSE686K025R0125 Application Field and Working Principle

Tantalum capacitors, also known as tantalum electrolytic capacitors or tantalum electrolytic capacitors, are usually made of tantalum powder, sintered under high temperature and pressure, and are formed after being injected with an electrolyte. The main structure of a typical tantalum capacitor consists of two metallic terminals and a ceramic dielectric material. This dielectric material is connected between the two terminals and separated by a thin oxide layer that forms between the anode and the cathode. The oxide layer can be formed by a variety of inorganic or organic materials, most notably polyanionic polymers electrolytes. The tantalum capacitors are widely used in various fields due to its excellent capacitance and tolerance, good stability and relatively low cost.The TPSE686K025R0125 is a multi-layer thick-film tantalum chip capacitor with a capacitance range of 2.2 uF to 100uF, a maximum voltage of 25 VDC, a wide temperature range of -55°C to +125°C, and an operating temperature range of -40°C to +85°C. This capacitor has high stability, low leakage current, high reliability and low ESR. The TPSE686K025R0125 is widely used in consumer electronic devices and other electronic equipment.In terms of working principle, a tantalum capacitor works by using the differences between positive and negative electric charges to create an electric field. When the electric field reaches a certain level, current starts to flow between the two metal terminals, which causes the dielectric material inside to become electrically polarized. This causes the material to store electric energy as it forms bubbles of charge that cycle between the two electrodes. The capacitor stores a specific electrical charge in both of its terminals, which is proportional to the level of voltage used. As the voltage fluctuates, the capacitor is able to store and release energy accordingly, resulting in a more stable electrical environment.The TPSE686K025R0125 has a wide range of applications in consumer electronic products, such as laptop computers, tablets, TVs, gaming consoles, and cell phones. It is also used for electric power supply, audio product, computer and communication product, automotive equipment, and various kinds of electric and electronic connections. In addition, it is applicable for use in isolating high voltage and low voltage circuits, electric noise filtering, power line filtering and isolation, feedback detection and signal transduction, current rectification and stabilizing, and power frequency suppression.Tantalum capacitors are well known for their high stability and low internal resistance, two of their most important features. They are also resistant to high temperatures, vibration and shock, meaning that they can be used in hostile environments. Their small size and lightweight make them ideal for integrating into portable and miniature electronics. Thanks to their wide range of applications, tantalum capacitors are becoming increasingly popular in today’s market.In conclusion, the TPSE686K025R0125 is a high-performance tantalum capacitor with excellent capacitance and tolerance, good stability, and low ESR. Its wide temperature range and high stability make it ideal for use in consumer electronic products and electronic equipment. Its small size and lightweight make it an ideal choice for use in portable and miniature electronics.
