Fixed inductors have a wide variety of applications in electric, electronic and IT industries, and they can be distinguished from other types of inductors depending on their uses in different applications. The CDR7D28MNNP-1R2NC fixed inductor has many applications, and in this article, we will discuss the application field and working principle of CDR7D28MNNP-1R2NC.

The CDR7D28MNNP-1R2NC is a type of surface mounted inductor designed and manufactured by Stackpole Electronics, Inc. It is one of the most widely used fixed inductors in the market and it has been designed for various applications such as power supply line filtering, electronic baluns, transformers, choke coils and pulse transformer applications. The CDR7D28MNNP-1R2NC has an inductance value of 7.5uH and resistance value of 225mΩ at 1kHz, and it is rated for 20% tolerance in all applications. The device has a maximum current rating of 5A and a dissipation rating of 2.5W. It features a high temperature operating range of -55°C to +125°C and it is available in various surface-mount packages such as 0304, 0402 and 0402LF.

The CDR7D28MNNP-1R2NC has numerous applications in electronic circuits, such as power supply filtering, line matching, pulse transformer applications and baluns. In power supply filtering activities, the device is used to reduce the high frequency noise in the power supplied to the circuits, by forming an LC filter network. In line matching activities, the device is used to match the impedance of circuit components such as capacitors, resistors and transistors. The device is also used in pulse transformer applications for the transformation of high frequency signals. Lastly, the device is used in baluns for the conversion of unbalanced signals into balanced ones.

The CDR7D28MNNP-1R2NC is a typical inductor with two terminals. Its working principle is based on Faraday’s Law of Induction, which states that the current in an inductor will induce an EMF in the inductor. When a current passes through the inductor, a magnetic field is induced around it which causes a voltage to be induced at its terminals. This voltage is known as the EMF of the inductor. The EMF will oppose the current flow if the current is increasing, but it will help the current flow if current is decreasing. The inductance (L) of the inductor can be calculated as the ratio of the induced EMF to the current.

In summary, the CDR7D28MNNP-1R2NC is a fixed inductor manufactured by Stackpole Electronics. It has several applications in power supply filtering activities, line matching, pulse transformer activities and baluns. The device has an inductance value of 7.5uH and resistance value of 225mΩ at 1kHz. The device works based on Faraday’s Law of Induction, where the induced EMF in the inductor opposes or helps the current flow depending on its direction.
