Fixed inductors are inductor components that do not have a variable doping element, and thus the inductance cannot be changed. The SRP4012-2R2M is one such inductor. It is a surface-mount inductor with C-shaped magnetic shield, which makes it suitable for high density printed circuit boards in thick film and high frequency applications. The SRP4012-2R2M has a shielding design which helps to reduce the effect of external magnetic fields and radio-frequency interference, making it a good choice for applications in challenging electromagnetic environments. The inductor has an inductance value of 2.2 μH and a maximum current rating of 1.5 A.

The SRP4012-2R2M is an air-core inductor and is constructed of all ceramic material. It has an operating temperature range of -55°C to +125°C and is RoHS compliant. The inductor has low DC resistance of 0.046 Ω and low self-resonant frequency of 600 MHz. It is also highly stable and reliable due to its low temperature coefficient of inductance.

The SRP4012-2R2M has a wide range of applications in power supplies, switching modes, RF, and high frequency communication systems. It is used in power converters, DC-DC step-down converters, car audio systems, loop antenna couplers, signal filters, RF antennas, cellular communications, and satellite communication systems. It is also used as an RF input DC blocking filter for RF modems and communication systems. In addition, it can be used as an output DC blocking filter for power supplies in car and industrial applications.

The working principle of the SRP4012-2R2M is quite simple. When electric current is applied to the inductor, a magnetic field is developed. This magnetic field stores energy in the form of inductance. When the current is removed, the stored energy is released, leading to an opposing current in the inductor.

The SRP4012-2R2M is an ideal choice for applications that require reliable operation in challenging electromagnetic environments. Its low temperature coefficient of inductance makes it highly stable and reliable, and its wide range of applications makes it a versatile component for high frequency communication and power supply systems.
