Fixed inductors are components that store energy in an electric field or a magnetic field when an electric current passes through them. The SRP1245A-5R6M is a fixed inductor that is designed to provide consistent, reliable and high-quality performance for a variety of industrial and consumer applications. This energy storage capacity is important for many electronics including amplifiers, power supplies, and voltage regulators. This inductor is also effective in reducing electromagnetic interference (EMI) generated from both digital and analog circuit operations.

The SRP1245A-5R6M is a fixed inductor in a radial leaded “square” form factor, and consists of a heavy duty ferrite core with a molded outer shell. The core is insulated with a layer of glass-filled epoxy. It has an inductance of 2.5 to 6.5 mH, a rated current of 7.4 A and a temperature range of -40 to 125 °C. The low resistance design allows for higher current handling, while the high saturation flux density maximizes its inductance value.

The SRP1245A-5R6M is typically used for energy storage and power conversion applications. As an inductor, it provides a path for current to flow from one point to another, preventing damage to the components or system. In power conversion, its high inductance and low current levels help prolong the datasheet specified input and output voltages, thus providing reliable performance under challenging conditions. With the use of DC/DC converters, it is even possible to boost or drop input voltage from one voltage level to another.

In a typical application, the SRP1245A-5R6M would be used as a current-limiting device in a source/load equipment. It would limit the peak current that can flow through the circuit, preventing the circuit from shorting out or overheating. This inductor is also used in frequency selection and voltage regulation circuits, as it can help regulate input and output voltages to the specified range. Other common uses include EMI-shielding, surge suppression, noise filtering, and power factor correction.

The working principle of the SRP1245A-5R6M is based on Faraday’s law of electromagnetic induction. When a varying current flows through the inductor, a varying magnetic field is created in the coil. This magnetic field induces an electromotive force in the coil, which causes an electric current to flow in a closed loop. The current in this loop is proportional to the induced electric field, the rate of change of the magnetic flux, and the number of turns in the inductor.

In summary, the SRP1245A-5R6M is a fixed inductor with an inductance of 2.5 to 6.5 mH. It is designed to provide consistent and reliable performance in a wide range of industrial and consumer applications. The low resistance design allows for higher current handling and its high saturation flux density maximizes its inductance value. It is typically used for energy storage, power conversion, EMI-shielding, surge suppression, noise filtering, power factor correction, and current limiting. The working principle of this device is based on Faraday’s law of electromagnetic induction.
