Fixed inductors are the most common type of inductor, used to overcome the shortcomings of traditional inductors where the core can be easily saturated. The CDRH125/LDNP-220MC from Coilcraft is an example of a fixed inductor, and here we will discuss its application field and working principle.

The CDRH125/LDNP-220MC is an axial leaded, medium-power inductor. It is very efficient, with an operating temperature range of -65°C to +150°C, and it can handle power loads up to 1.8A. It is available in a range of shielded and unshielded types, and also offers various tolerances to suit different applications. It is also available in axial and surface mount versions, making it a versatile and popular choice.

The main applications of the CDRH125/LDNP-220MC fixed inductor are power circuits, DC-to-DC converters, switch mode power supplies, low voltage motor driving circuits, and automotive applications. It is particularly useful in these applications because of the wide power range and operating temperature, and the many different types and tolerances available.

The working principle of the CDRH125/LDNP-220MC fixed inductor is fairly simple, based on Faraday’s law of induction. When an electric current passes through a wire or other conductive material, a magnetic field is created. This magnetic field exerts a force on other nearby metallic objects, producing an electric current in them. Since the electric current always takes the path of least resistance, it will tend to flow through the fixed inductor, producing an inductance.

The CDRH125/LDNP-220MC uses these principles to provide a reliable, efficient medium-power inductor for many applications. The choice of shielded versus unshielded versions lets users customize the inductance values for the specific application, while the various types and tolerances provide more versatility. The wide operating temperature and power range make the CDRH125/LDNP-220MC suitable for a wide range of applications, from low voltage motor drivers to DC-to-DC converters.
