• ADC and DAC circuits, where the CIGT201210UMR47MNE can suppress high frequency switching noise by blocking high frequency current without degrading the overall performance.

Working Principle

The CIGT201210UMR47MNE is a wound inductor. The winding is constructed of a single or multiple layers of wire, which is insulated between each layer. When an AC voltage is applied across the coil, it induces a magnetic field within the core material, producing an opposing EMF. This opposing EMF is proportional to the amount of current flowing in the coil and is known as the inductance of the coil.The resistance of the coil is determine by the materials used to construct the coil. The resistance of the copper wire, along with the winding resistance of the coil, make up the overall resistance of the CIGT201210UMR47MNE. The resistance defines the amount of voltage drop across the CIGT201210UMR47MNE and is used to help optimize the circuit performance.

The CIGT201210UMR47MNE is very versatile and can be used in a variety of applications. It offers good current handling capabilities and has excellent EMI suppression characteristics, which makes it ideal for use in any power line filter or high frequency DC/DC converter circuit.
