Fixed inductors are most commonly used in power-supply designs. The most common type is an inductor that is stationary and not adjustable. The CD75NP-121KC is an example of this type of inductor which will be explained in more detail in the following sections.

The CD75NP-121KC is a surface mount inductor constructed using copper wire wound on a ferrite core. The total inductance of the device is rated at 121uH with an inductance tolerance of ±25%. The part is rated at 1 Amp and has a temperature range of -25°C to 115°C.

The application field of CD75NP-121KC includes power supplies, switching mode power supplies (SMPS), DC/DC converters, and DC-to-AC inverters. This specific fixed inductor is suitable for use in applications that require a high-current, high-performance part. Additionally, it can help reduce any electromagnetic interference (EMI) and RFI issues, as it is designed to minimize stray inductance.

As for the CD75NP-121KC’s working principle, it is a combination of Faraday\'s law of induction and basic electrical properties of an inductor. The two key components of an inductor are the core and the wire. When electric current passes through the wire, it creates a magnetic field around the core. This field produces an opposing voltage, which helps reduce changes in voltage and current. An inductor is basically a component that stores energy in its magnetic field. This energy can be used to help regulate the output voltage and current of an electronic device.

The CD75NP-121KC is designed to have high current handling and reliability. In addition to this, it is also built to reduce the amount of EMI emission from the device. Thanks to the combination of the ferrite core and thick copper wire, the CD75NP-121KC exhibits excellent EMI suppression characteristics.

In summary, the CD75NP-121KC is a fixed inductor that is used in power supplies, switch mode power supplies, DC/DC converters, and DC-to-AC inverters. It is rated at 1 Amp and has a temperature range of -25°C to +115°C. Its working principle is based on Faraday’s law of induction, and its design enables it to reduce EMI emission in the device.
