Fixed Inductors

Fixed inductors are passive devices which have a constant electrical inductance. Commonly used in various electronic circuits, it creates a magnetic field that increases or decreases the electrical current flow. The CM201212-68NKL is a type of fixed inductor developed specifically for use in low power switching applications.

Application Field

The CM201212-68NKL is used for a variety of low power switching applications, such as mobile phones, wireless routers, and other portable electronics. It is designed to provide low power switching, low profile size, and high surge currents. Additionally, it is designed to be compliant with the RoHS Directive and is suitable for SMT assembly.

Working Principle

The working principle of the CM201212-68NKL fixed inductor is based on the conductance of the inductor’s core material. Inductors consist of two main components: a core material and a conductor. The conductor is wound around the core material and as electrical current passes through it, a magnetic field is generated around the core material. When the current flow is increased, the magnetic field increases and so does the inductance of the inductor. This increase in inductance causes the electrical current to slow down, which in turn creates a voltage drop. The CM201212-68NKL’s core material is made from ferrite, a ceramic material that is particularly good at withstanding voltage and temperature changes. The conductor consists of a copper wire which is insulated with an enamel coating. As the electrical current passes through the wire, it’s resistance causes a voltage drop. This voltage drop is what causes the inductor to limit the current in the circuit. The CM201212-68NKL’s core material also helps protect the inductor from high surge currents. The core material helps absorb and dissipate the excess energy which helps keep the inductor from overheating or being damaged. The inductor is also designed to have a low internal resistance so that it can handle high frequency switching applications.

Conclusion

The CM201212-68NKL is a high performance fixed inductor designed specifically for low power switching applications. Its core material is made from ferrite which offers excellent temperature and voltage stability. Additionally, its low internal resistance and surge current protection makes it suitable for high frequency switching. As a result, the CM201212-68NKL is an ideal choice for a variety of portable electronic applications.
