Fixed inductors are a type of electrical component whose inductance is static (constant). The CR75NP-121KC is such a fixed inductor. It has a wide range of applications due to its size and characteristics. This article will discuss the application field and working principle of the CR75NP-121KC.

The CR75NP-121KC is a ferrite core fixed inductor manufactured by Murata. It is used in many different applications, such as power filters, noise suppression circuits, filtering circuits for low-voltage DC (direct current) power supplies, resonant circuits, and noise filters for automotive electronics. The device is widely used in consumer electronics because of its small size and high performance. Its operating temperature range is also wide, from –40°C to +85°C.

The CR75NP-121KC has a rated inductance of 121nH. It has a rated current of 7.0A and an equivalent series resistance of 8.20 mΩ. It has an excellent rated current to size ratio and a low equivalent series resistance, making it ideal for use in low-voltage DC power supplies. The inductor is also RoHS (Restriction of Hazardous Substances) compliant, meaning it meets the European Union\'s hazardous materials regulations.

The working principle of the CR75NP-121KC is based on the principles of inductance. An inductor consists of a coil of wire wound around a core, typically made from a ferrite material. When a current passes through the coil, a magnetic field is generated. This field causes the inductance of the coil to increase. The change in inductance, which is referred to as inductance reactance, is proportional to the amount of current passing through the coil.

The CR75NP-121KC has a high operating temperature range and a low equivalent series resistance, making it suitable for use in a wide range of applications. It also has a wide range of possible mounting configurations, from surface mounting to through-hole mounting. Its small size also makes it well suited for use in consumer electronics.

In summary, the CR75NP-121KC is a ferrite core fixed inductor with a wide range of applications. It is RoHS compliant and has a wide operating temperature range, a low equivalent series resistance, and is also capable of being mounted in a variety of configurations. The inductor works by generating a magnetic field when an electric current passes through its coil, which increases its inductance reactance. The CR75NP-121KC is an ideal choice for many different applications.
