Fixed inductors are the components used to store energy in the form of a magnetic field, and then convert the energy to a current output. SRP3012TA-3R3M is one kind of fixed inductor with application field of it rooted in power supply and power equipment. The specific working principle and advantages of SRP3012TA-3R3M will be illustrated in the following.

SRP3012TA-3R3M is a kind of radial-lead, wire-wound polar inductor specially designed for switched mode power supplies, and the core is made up of or nickel-zinc ferrite. This kind of product features with high temperature resistant, anti-interference, high current and low resistance. The temperature resistant of SRP3012TA-3R3M can reach to 150 degrees Celsius. And its sized follows the standard dimensions respectively. Besides, this kind of inductor has a wide operating temperature range from -40 up to +125 °C, working under full rated power but low temperature rise.

As to the working principle of SRP3012TA-3R3M, it is based on the Faraday effect: when the current passes through the primary winding of the inductor, it generates a changing magnetic field. This changing magnetic field induces an electric current in the secondary winding of the inductor. The current in the secondary winding is therefore of opposite direction to the primary winding. This process can be repeated when the change of current terminates and the opposite current resumes.

The drawbacks of the SRP3012TA-3R3M are power losses in both primary and secondary windings due to winding resistance, and the size of the inductor can become quite large if the inductance value is too high. High winding resistance would lead to a high temperature rise and the output voltage may drop.

In summary, SRP3012TA-3R3M is one kind of radial-lead, wire-wound polar inductor suitable for switched mode power supplies. It is a device that relies on the Faraday effect to store and convert electrical energy. This product is characterized by high temperature resistance, anti-interference, high current and low resistance, but it also has some shortcomings such as power losses and size.
