SRP1040-2R2M Working Principle

The SRP1040-2R2M is a wound-chip inductor which works on the principle of Faraday’s law of electromagnetic induction. This law states that when voltage is induced across a conductor, an electric current is produced. This current is proportional to the rate of changing flux through the conductor. The wire core of the SRP1040-2R2M is constructed of an insulated copper wire, which is then wound around a ferrite or powdered iron core. The magnetic field created by the current flowing through the wound conductors interacts with the core, creating a magnetic field which induces a voltage across the conductor. This induced voltage is then utilized in a variety of electrical applications.

The SRP1040-2R2M is suitable for use with high frequency switching supplies, Class D audio amplifiers, cellular telephone, power line communication equipment, and other high frequency applications. It has a low DCR and very low losses, making it an ideal choice for digital signal transceivers as well as DC to DC converters. It is also suitable for automotive applications due to its high resistance to shock and vibration.

The SRP1040-2R2M is a small size and highly reliable inductor that can be used in a variety of electrical applications. Its high linearity, low DC resistance and high ripple current make it an ideal choice for high frequency switching power supplies, audio applications, and digital signal transceivers.
