Tantalum Capacitors

Tantalum capacitors are the type of capacitors that are developed from the tantalum family elements, tantalum and tungsten carbide. They are small, low profile and can store higher amounts of electrical energy than other types of capacitors. The specific kind, TRJB156M016SRJ capacitors, made from tantalum and tungsten carbide, can guarantee better response and performance in a wider range of applications.

Applications

Tantalum capacitors are widely used in electronics due to the excellent electrical and structural performance they offer. They are used in many fields of technology, such as communications, aerospace and defense, medical and automotive, as well as in consumer electronics, including computers, mobile phones, wearables and other electronic gadgets. For communications, the capacitors are used in high frequency filter circuits, decoupling and bypassing power supplies and other oscillator circuits. In the defense sector, they provide reliable power supplies, thus contributing to fail-safe performance in critical applications. In medical, they are used as oscillator circuits and high frequency filter circuits, helping to make medical equipment more reliable. Similarly, in automotive, the capacitors are used in many different applications for their very reliable operation.

Working Principle

Tantalum capacitors, including the TRJB156M016SRJ, are polarized capacitors. They are made of thin layer of tantalum oxide and an electrolyte, usually aqueous solution, under a dielectric layer, usually Kemet plastic film. When an electric field is applied between the anode and the cathode, it creates a uniform electric field. This field results in an electric displacement current that is proportional to the applied electric field. The amount of charge stored in the TRJB156M016SRJ capacitor is proportional to the capacitance of the capacitor. The production of this charge is known as the ‘charging effect’ of the capacitor.

Advantages

Tantalum capacitors have many advantages over other types of capacitors. They have low leakage current, have a high dielectric constant and have extremely low losses. They have high capacitance values in a small package, making them attractive in space-restricted electronic designs. They are also very reliable and have a long life expectancy, making them ideal for general purpose use. The TRJB156M016SRJ is designed for high frequency applications, with a tolerable frequency up to 40kHz. It has a high ripple current capacity, allowing it to handle high voltage surges, and a low ESR (Equivalent Series Resistance), allowing for lower power dissipation. The capacitors also offer high operating temperatures, allowing for a more reliable operation under high temperatures.

Conclusion

Tantalum capacitors, and specifically the TRJB156M016SRJ, are made of tantalum and tungsten carbide, and are used in many different applications due to the excellent electrical and structural performance they offer. The capacitors are used in communications, defense, medical, automotive, and consumer electronics due to their high capacitance, low leakage current, and long life expectancy. The TRJB156M016SRJ also has a high ripple current capacity, low ESR, and a high operating temperature, making it suitable for high frequency applications.
