Fixed Inductors

Inductors are passive electrical components used to store energy in the form of a magnetic field. Fixed inductors are generally designed to have a low impedence when exposed to alternating currents, and can be composed of various materials, such as ceramic, wire, or ferrite. One type of fixed inductor is the CIG21W1R5MNE, which is primarily used in switching power supplies.

The CIG21W1R5MNE is composed of ferrite material wound into a small cylindrical shape with a layer of silicone insulation around it. Lengthwise, the inductor is about 21 millimeters long, with a diameter of 11 millimeters. It has a maximum DC resistance of 1.5 ohms and is rated to operate at a maximum of 20A. Its inductance is rated at 1.2mH.

When used in a switching power supply, the CIG21W1R5MNE acts as a filter of the current entering into the integrated circuit. Its circuitry helps to maintain a steady supply of voltage to the integrated circuit, while also protecting it from various electrical disturbances and anything potentially harmful. The inductor also helps to reduce the power dissipation caused by the rapid on-off current switching.

The CIG21W1R5MNE is specifically designed to handle high levels of temperature, up to 155 degrees Celsius. Additionally, it has a good EMI and RFI protection, which prevents interference from outside sources such as cellular phones or FM radios. With its good reliability and resistance to dielectric breakdown, the CIG21W1R5MNE serves as an ideal component for use in circuit board applications.

Overall, the CIG21W1R5MNE is a high-quality fixed inductor, designed to handle high levels of electrical current and temperature, as well as other environmental disturbances. It is mainly used in switching power supplies, where it helps to maintain steady voltage and protect the integrated circuit from electrical disturbances. It is also reliable and resistant to dielectric breakdown, making it an ideal component for various circuit board applications.
