Fixed inductors represent an essential component of electronic circuits and play an important role in the transmission, production or storage of electric energy. From simple resistance-inductance circuits to power supplies and audio applications, the demand for fixed inductors is high. CIG22H1R2MAE is one of the most commonly used fixed inductors and this article will provide an overview of this device’s application field and working principle.

One primary application of CIG22H1R2MAE is in power supplies, where it is used as a primary choke coil. A primary choke coil is the key part of an EMI filter, allowing the filter to reduce the electromagnetic interference generated by the power supply and protect delicate devices from it. CIG22H1R2MAE also finds use in differential mode applications, where it operates as a differential mode filter, which is necessary when using downstream stages in high speed applications, such as DDR2 and DDR3 memory and digital signal processor (DSP) power supplies.

CIG22H1R2MAE also has multiple roles to play in audio applications. Its primary use is as a metal-oxide-fuse (MOF) type noise filter, where it is used to reduce high-frequency noise, ensure desired sound quality and prevent interference between signal lines. CIG22H1R2MAE is also used as a common mode filter due to its low signal-dependent distortion levels and high-frequency characteristics, which allow it to accurately convert electrical signals.

The working principle of CIG22H1R2MAE is based on the same principles as other fixed inductors. This inductor is a passive two-terminal device and works by storing electrical energy in its magnetic field and then releasing it in the form of a current at a specified rate. Electrical current passes through the coil and generates a magnetic field stored in the inductor. When the current is cut, the magnetic field collapses and generates a current in the opposite direction. This current is released in the form of a voltage, completing the cycle.

Another important aspect of CIG22H1R2MAE is its electrical characteristics. It has a nominal inductance of 42.4 uH, a DC resistance of 10.4 ohms, a maximum operating frequency of 10MHz, a rated current of 2.6A and an operating temperature range of -25°C to +100°C.

In summary, CIG22H1R2MAE is a fixed inductor designed for power supply and audio applications. It finds use in power supplies as a primary choke coil and in audio applications for metal-oxide-fuse type noise filter and common mode filter. Its working principle is based on the two-terminal device principle and it has specific electrical characteristics, including a nominal inductance of 42.4 uH, a DC resistance of 10.4 ohms, a maximum operating frequency of 10MHz, a rated current of 2.6A and an operating temperature range of -25°C to +100°C.
