Fixed inductors are widely used in a variety of electronic systems, such as home appliances, auto start and stop systems, and signal conditioners. A wide variety of inductor designs, with different performance characteristics, are available to meet specific requirements. The SRP5030CA-1R2M, a series of inductors produced by Rohm, is among the most popular in the electronic industry.

The SRP5030CA-1R2M series of inductors are designed for operation in high frequency, high power applications. The core material is made up of iron powder which ensures excellent inductance stability with minimal flux leakage. The inductor has low DC resistance to reduce power loss. The low parasitic capacitance ensures low parasitics and thus minimal interference with other components in the system. The inductors are lead-free and RoHS compatible with other standard electronic components.

The SRP5030CA-1R2M series of inductors are ideally suited for use in power converters, battery charging systems, power supply controllers, and motor control power circuits. These inductors can be used in various DC-DC converters, from low voltage low power up to high voltage and high current applications. The inductors are suitable for use in high frequency switching power supply converters and can be used to reduce ripple noise and improve power factor. The inductors are also ideal for use in automotive and other harsh environmental applications.

The working principle behind the SRP5030CA-1R2M series of inductors is based on Faraday’s Law of Induction. Faraday’s Law states that an electric current can induce a magnetic field in an electrical circuit. When a conductor carrying an electric current is placed in a magnetic field, an electromotive force or EMF is induced in the conductor. An inductor makes use of this principle to store energy in the form of a magnetic field. When current is applied to the inductor, the magnetic field surrounding the inductor core stores the energy in the form of a magnetic field.

When the current is removed from the inductor, the magnetic field collapses and generates an induced EMF in the coil. This induced EMF causes a voltage to appear across the inductor terminals and is known as a back EMF. The magnitude of the back EMF is proportional to the rate of change of the current in the inductor. The higher the current rate of change, the higher the back EMF. The induced EMF or back EMF opposes the current change, thus limiting the rate of current change in the circuit.

The SRP5030CA-1R2M series of fixed inductors combine a low resistance core material with unique construction to ensure a low parasitic capacitance, high dielectric strength, low DC resistance and high resistance to environment aging. These features make the SRP5030CA-1R2M series of fixed inductors ideal for use in high power applications that require high frequency switching, robustness, and excellent performance.
