Fixed Inductors are an essential component of many power and signal circuits. SRP7028A-220M is a type of fixed inductor, which combines the performance of conventional transformers and inductors into one device. It is ideal for use in applications that require high switching frequencies, high cycling rates, and high efficiencies.

Construction of SRP7028A-220M

SRP7028A-220M is a surface mounted device which is constructed by a cylindrical magnet core, a coil winding, a ferrite shield, and a damping material. The cylindrical magnet core provides the magnetic structure, the coil winding provides the electrical connections, and the ferrite shield reduces interference from external sources. The damping material is used to absorb stray electromagnetic fields that may otherwise affect the performance of the device.

SRP7028A-220M Application Field

The SRP7028A-220M can be used in a variety of applications. It is capable of providing inductance in the range of 1.0 to 4.2 mH, with current ratings up to 800 mA. This makes it suitable for applications which require a high switching frequency, such as in DC-DC converters. Additionally, the device is well suited for use in noise suppression circuits, where it can reject interference from external sources and reduce EMI emissions.

SRP7028A-220M Working Principle

The working principle of SRP7028A-220M is based on Faraday\'s law of induction. When a current is passed through the coil winding of the device, a magnetic field is generated. This magnetic field then induces an opposing current in the external circuit, which opposes the initial current. The magnitude of the opposing current is determined by the inductance value of the device.

The current-dependent inductance of an SRP7028A-220M allows it to operate efficiently even when high current levels are present. Furthermore, the device is capable of maintaining its performance over a wide range of temperatures, making it suitable for use in industrial, automotive, and other applications.

Conclusion

The SRP7028A-220M is an efficient and reliable fixed inductor that can be used in a variety of applications. It combines the performance of conventional transformers and inductors into one device, making it ideal for use in applications requiring high switching frequencies, high cycling rates, and high efficiencies. The device is also well suited for use in noise suppression circuits, where it can reject interference from external sources and reduce EMI emissions.
