Fixed inductors are electrical components designed to store an electrical charge in the form of a magnetic field. They are generally composed of a coil of wire, a core material, and a casing. Fixed inductors are used in a variety of electrical circuits to shape and filter out different frequency signals, controlling the flow of current in the circuit.

The CR75-4R7MC is a fixed inductor manufactured by Coilcraft. This particular product has an inductance range of 4.7 microhenry and an operating temperature range of -55 to +125 degrees Celsius. It is designed for general purpose applications, such as decoupling or voltage-level shifting.

The CR75-4R7MC is a four-layer, molded construction that imparts excellent mechanical and electrical stability. This helps it to maintain a constant performance over a wide temperature range. The core material used is ferrite, which provides increased current-handling capabilities without compromising size. Each inductor comes with a plastic casing to protect against dust and dirt.

The main advantages of the CR75-4R7MC are its low profile design, low magnetic leakage, and low temperature coefficient. Its low profile design allows for easy integration into most assembly types, while its low magnetic leakage ensures minimal interference with other components. Its low temperature coefficient further enables the use of this inductor in a wide range of applications, including automotive systems.

The CR75-4R7MC’s working principle is based on the principle of Faraday’s Law of Electromagnetic Induction. This law states that a changing magnetic field will induce a voltage in a closed circuit. In the case of the CR75-4R7MC, a changing current will flow through the inductor’s coil, generating a magnetic field. This magnetic field will induce a voltage in the circuit, creating an electromotive force (EMF). The magnitude of the EMF will be proportional to the rate of change of the current.

The CR75-4R7MC is a versatile, reliable fixed inductor that can be used in a wide variety of applications. Its low profile design, low magnetic leakage, and low temperature coefficient make it ideal for automotive, telecom, and consumer electronics applications. Its operating temperature range of -55 to +125 degrees Celsius and core material of ferrite also make it suitable for harsh environments.
