Fixed inductors refer to the inductance element that does not change its inductance value under normal conditions. They are widely used in electronic circuits, and usually find in the applications such as frequency selection, tuning circuits, circuit Q adjustment, oscillator circuits, and pulse circuits.

CDRH73NP-681MC-B is a fixed inductor. The main features of this inductor are, it has an operating temperature range of -40 to 105°C, high current up to 7.7A, frequency up to 7,80MHz, and a metalized magnetic shield which minimises the radiation of generated noise.

CDRH73NP-681MC-B has various applications in different electronic systems. Commonly, it is used in Regulation Circuit, Regulated Power Supply, Protection Circuit, and Filtration Circuit. Besides, it also used in AC/DC Motor Driving Circuit, DC/DC Converters, AC/DC Switching Circuit, and Overcurrent Detecting circuit.

The working principle of this inductor lies in the current of its coils, when the current flowing in the coils is varying, there is an induced electromotive force (EMF) produced, usually in opposite direction around its coil. This induces EMF rises the resistance of the coils, and cuts off the current in the coils. The threshold of the EMF depends on the material and dimension of the coils and the resistivity of the material. Thus, this device is a key component of many circuits.

To sum up, CDRH73NP-681MC-B fixed inductor is widely used in different electronic applications. Its operation principle relies on the principles of electromagnetism, which the induced EMF between its coils will cause changes in its resistance. Therefore, this inductor is capable of controlling the circuit current efficiently.
