Tantalum capacitors are some of the most versatile components used in electrical engineering today. Generally, they\'re used to provide electrical charge storage and/or as a coupling capacitor to filter out high frequency signals. If a product requires a higher voltage rating than what’s available in standard ceramics, then tantalums are often considered.

The TLJR476M010R3200 is a type of tantalum capacitor that is specifically designed to provide a high capacitance value in small case sizes. It has an expansive application field and effective working principle. Let\'s take an in-depth look at the characteristics, applications and working principle of the TLJR476M010R3200.

Characteristics

The TLJR476M010R3200 is a nut and bolt-style, molded tantalum capacitor with a 4 terminal design. It has a capacitance of 4700μF and a voltage rating of 10V. Its leakage current is exceptionally low, making it suitable for high voltage and power applications.

The TLJR476M010R3200 also features a X7R dielectric, which means that it can tolerate applied voltage transients and spikes. Additionally, its temperature coefficient (TC) is "better than ±15%", which means that it is capable of operating within the temperature range of -55°C to +125°C.

As a result of the above characteristics, the TLJR476M010R3200 is ideal for use in applications where ultra-low leakage, high capacitance and stability is required. In addition, it is also highly resistant to electrical shock and vibration.

Applications

The TLJR476M010R3200 has several useful applications. Its extremely low leakage current and wide temperature range make it ideal for use in battery-powered devices, where it can be used to provide a continuous power supply. It is also used in power supplies, dc/dc converters, inverters, and servo motors.

The TLJR476M010R3200 is also commonly used in military and defense applications, as its X7R dielectric allows for operation in extreme environmental conditions. Its rather small size also makes it ideal for use in space-constrained applications, such as those found in handheld or portable devices.

Working Principle

The TLJR476M010R3200 is a type of capacitor called a “tantalum capacitor”, which means that it utilizes the element tantalum to create a charge storage device. A tantalum capacitor stores electrical energy in an oxide layer on the surface of its tantalum core, which then is then released when the capacitor is discharged.

The process is rather simple. When applying a positive voltage to the cap, the oxide layer on its tantalum core absorbs the positive ions. This causes the capacitor to become polarized, which stores the electrical energy. When a negative voltage is applied to the capacitor, the positive charge stored in the oxide layer is released, causing electrical current to flow.

The TLJR476M010R3200 works on this principle, but with the addition of a dielectric material in between the layers known as the X7R material. This allows for a more efficient charge transfer and higher stability than traditional tantalum capacitors.

Conclusion

The TLJR476M010R3200 is an effective and reliable component for power conversion and high frequency applications. Its expansive application field, low leakage current and excellent temperature coefficient makes it an ideal choice for numerous applications. It is also energy efficient, making it perfect for battery-powered applications. Ultimately, the TLJR476M010R3200 is a useful component for any design engineer.
