Fixed Inductors are electrical components that absorb energy in the form of inductive reactance when electricity flows through them. IHSM4825RE390L is a fixed inductor from Würth Elektronik, available in 7mm×7mm×3.15mm SMD size. The applications range from mobile phones, car audio electronics, medicals, and consumer electronics such as laptop adaptor and motordrivers. This components is designed to offer high performance and excellent stability in those applications.

Working Principle

Fixed inductors are widely used for various applications. An inductor is a circuit component consisting of wire or some other conductive material wound into a coil that can store energy temporarily in the form of a magnetic field. When a current is applied, the coil produces a magnetic field that ‘induces’ a voltage within itself. This induction is the key phenomenon that makes fixed inductors work.

The inductance of the coil is equal to the resistance of the coil multiplied by the amount of current flowing through it. The more turns of the coil, the greater this induction will be. This is why the size of the components is important: the larger it is, the more turns of the coil will be added to the total number of turns in the component, thereby increasing its inductance.

When a current is applied to an inductor, it creates an opposing current, known as a Faraday back current. This current can oppose or aid in the flow of current, depending on the direction of the current. If the current and Faraday back current are flowing in the same direction, the inductor “loads”, creating a more difficult path for the current to flow. This is known as inductive reactance and is measured in ohms.

The IHSM4825RE390L is designed to serve low-frequency applications. It provides higher inductance while keeping low DCR (series resistance). Its efficiency is guaranteed due to its special winding technique, temperature stability on inductance characteristics, and preventing environmental stress from interference.
