Tantalum capacitors are widely used in consumer electronics and other electronic devices. Their excellent electrical properties make them ideal for high-frequency applications. The TM3D157M004CBA is a type of tantalum capacitor specifically designed for demanding applications where high capacitance is required.

Application Field of the TM3D157M004CBA

This type of capacitor is primarily used in industrial equipment and military equipment, where high capacitance and reliability are essential. It is also ideal for medical and automotive applications, high-voltage supplies, and power supplies. In addition, the TM3D157M004CBA can be used in systems that require very low leakage current, such as laptop computers, PDAs, and mobile phones.

This type of capacitor offers a particularly high reliability and a big range of capacitance options, up to 10 microfarads. It is also able to operate at temperatures ranging from -55° to 185°C. Thanks to these features, the TM3D157M004CBA is suitable for applications that need to withstand extreme temperature changes and vibrations. Moreover, its compact size make it a great choice for space-limited applications.

Working Principle of the TM3D157M004CBA

Like all tantalum capacitors, the TM3D157M004CBA uses a sintered anodic layer of tantalum pentoxide as its dielectric material. This material has excellent dielectric properties, allowing high capacitance values with minimum amounts of current leakage. The cylindrical form of the capacitor is made of tantalum and niobium, and it is sealed with a metal or plated-metal lid.

When used in a circuit, the capacitor works by storing an electric charge on its electrodes. The positive electrode is made of tantalum and the negative electrode is made of niobium. When a voltage is applied, the negative and positive charges on the two electrodes move towards each other, creating a capacitance between the electrodes. The amount of capacitance depends on the size of the electrodes and the distance between them.

The key feature of the TM3D157M004CBA is its ability to handle higher voltages than regular tantalum capacitors. This is due to the superior dielectric strength of its metal-lidded construction, which allows the device to handle higher voltages without failing.

Conclusion

The TM3D157M004CBA is a type of tantalum capacitor designed for demanding applications. Its excellent electrical properties make it ideal for high-frequency applications, offering a high reliability and a big range of capacitance options. Additionally, its ability to handle higher voltages and its compact size make it suitable for space-limited applications. Its working principle relies on an anodic layer of tantalum pentoxide that allows very high capacitance values with minimum current leakage.
