Working Principle of the 1812R-680M

The 1812R-680M is a non-polarized, ferrite-core, surface-mount component. It has a rated inductance of 680mH and a resistance of 0.32 ohms. It has an insulation resistance of 250m hours and the rated current has a maximum value of 2A. The working power of the part is 3.1W and the working voltage is 2.5V. The insulation classification of the part is UL-J-950V and the dimension of the part is 1812.

The working principle of the 1812R-680M can be described as follows. When a current passes through the inductor, the magnetic field generated by the current produces an opposing force to the current, according to Faraday\'s Law of Induction. This creates a voltage across the inductor, which is directly proportional to the rate of change of the current. This voltage can be utilized to control the current in a variety of applications such as voltage regulators and power converters.
