T491B106K020AT4380

Tantalum capacitors are a type of electrolytic capacitor. They provide superior frequency, performance and structural stability over other types of capacitors. This makes them ideal for a variety of applications, from audio and video equipment to industrial power supplies. The T491B106K020AT4380 is a Surface Mount Tantalum Capacitor, which is a type of polarized capacitor that consists of tantalum metal as an anode, surrounded by oxide material.

Key Specifications

The key design specification with the T491B106K020AT4380 is the capacitance (6.3uF) and temperature range (85°C to 105°C). It features a voltage rating of 16vDC, a tolerance of ±20% and a 20mm x 17mm physical size. It also has an endurance of 1000h @ +85°C.

Working Principle

The working principle of a tantalum capacitor is similar to that of any other polarized capacitor. When a voltage is applied, electrons are drawn from the anode to the cathode, creating electrical charge trapping in the oxide layer. This electrical charge is what makes up the capacitance of the capacitor. The higher the voltage and amount of electrons, the greater amount of charge can be stored.

Application Fields

The T491B106K020AT4380 is suitable for a broad range of applications, such as audio and video equipment, industrial power supplies, and any other device requiring a high-performance and reliable capacitor. Due to its low leakage current and low height profile, this capacitor is widely used in the consumer electronics industry.

Conclusion

Tantalum capacitors are one of the most reliable and widely used types of capacitors. The T491B106K020AT4380 is a low profile, high performance surface mount tantalum capacitor that is suitable for a wide variety of applications.
