Fixed Inductors

An induction coil, also known as a fixed inductor, is an electrical device constructed using several turns of insulated wire wrapped on a cylinder, known as a bobbin, often made of metal or plastic. The principle behind the device is based on Faraday’s law of induction. This law states that when a varying magnetic field is passed through a circuit, it creates an induced electromotive force. The electrons in the coil of the induction coil get pushed in the same direction by the varying magnetic field, causing an increase in current. This current is then used as the source of power for an electrical device.

0420CDMCDS-R47MC Application Field and Working Principle

The 0420CDMCDS-R47MC is an inductor designed to provide high frequency filtering and isolation, especially in applications such as DC-DC converters, power supplies, wireless communication, audio applications, instrumentation and data acquisition. The inductor is rated up to 15A and features a saturation current of 82.27A.

Its main application is power line filters used to decrease any strong off-site signal or electronic noise coming down the power grid. The inductor is also used in switching supplies, as it helps reduce wire volume and the coil\'s inductance when the power line is switched on or off. This helps reduce the EMF generated by the transmission circuit as well as potential switching losses.

The 0420CDMCDS-R47MC is designed using toroidal windings. Toroidal windings help reduce the amount of wire used for the inductance while providing high frequency isolation. The construction of the device is based on Faraday’s law of induction which states that when a varying magnetic field is passed through a circuit, it creates an induced electromotive force. This electromagnetic force is applied to the windings of the inductor, generating an electrical current. This electrical current is then used to provide power to an electrical device.

The 0420CDMCDS-R47MC inductor features a high-frequency isolation and is an excellent choice for use in applications such as DC-DC converters and voltage regulators, power supplies, wireless communication, audio applications, instrumentation, and data acquisition. The toroidal windings and high-frequency isolation make it a great choice for any of these applications where a reliable, clean power line is required.
