Fixed Inductors

Inductors are electrical components with basic functions such as storing or releasing energy, voltage regulation, filtering, and impedance transformation. The basic component of the inductors is the coil. The SRP4012TA-R36M is a widely used fixed inductor. This article discusses its application field and working principle.

Application Field of SRP4012TA-R36M

The SRP4012TA-R36M is a general-purpose fixed inductor, suitable for use in DC-DC converters for portable devices, PCs, consumer electronics, cellular phones, automotive electronics, and other commercial products. It is specially designed for high current applications, and due to its small size and high current rating, it is suitable for mounting in limited spaces. Its high current rating also allows it to handle high current requirements for portable devices, even when mounted on the board.

Working Principle of SRP4012TA-R36M

The SRP4012TA-R36M works by storing energy in the form of an electrical field. This energy is stored as a result of the electric current passing through its coils. When the current is stopped, the electric field dissipates releasing the stored energy. The parameters which influence the inductance value of an inductor are the number of turns in its coil, the magnetic permeability of the core material, and the core material’s geometry.The SRP4012TA-R36M has an extremely low DC resistance, allowing it to operate at higher frequencies with less power loss. Its small size and low profile helps to improve its performance in high-speed circuits. Its high-temperature rating and high heat dissipation capabilities make it suitable for long-term and high reliability applications.The inductance value of the SRP4012TA-R36M is around 39uH. Its tolerance level is +/- 10% and it is rated for maximum current of 4.2A. It also has a temperature range of -40°C to +125°C. Thanks to its robust electrical and physical design, it also provides excellent frequency performance across a wide range of applications.

Conclusion

In conclusion, the SRP4012TA-R36M is a reliable fixed inductor with wide applications in both consumer electronics and commercial products. Its features, including its low DC resistance, high current rating, small size, and high temperature rating make it suitable for a range of different applications. Its high-performance design also makes it suitable for high-speed circuits and long-term reliability applications.
