IHSM4825EB270L

Fixed Inductors, also known as inductors, perform the same basic job as chokes—storing energy in a magnetic field created by the current running through them. The IHSM4825EB270L is a symmetrical, dual in-line, shielded, surface-mount fixed inductor for automotive applications. Offering 500 VDC maximum operating voltage, this device has high reliability due to its broad operating temperature range from -40°C to +125°C.

The IHSM4825EB270L fixed inductor is designed to meet the stringent requirements of automotive power transmission applications such as starter motors, alternators, wiper motors, fluids pumps and vehicle accessories. It is intended for use in high-efficiency DC/DC converters, switching power supplies, and line EMI filters.

due to its low dc and ac resistance, the IHSM4825EB270L can achieve up to 90 percent energy conversion efficiency. The double shielded construction of the inductor offers excellent thermal transfer and vibration performance. Moreover, the heat resistant magnetic material used for core construction offers superior long-term stability and reliability.

In terms of its working principle, the IHSM4825EB270L fixed inductor operates through induction. Inductance is generated when an alternating current passes through the device, and the flow of current within the inductor affects the voltage across it. In essence, the inductance creates a reluctance to the current flow, which in turn creates an opposing electromagnetic field determined by the number of turns in the coil. The more turns an inductor has, the greater the inductance and the better the current—voltage relationship.

At the same time, the core shape and construction of a fixed inductor significantly affect its inductance value and inductive reactance. By choosing the correct core material and construction for a particular application, engineers can minimize the coil loss caused by flux leakage and resistive power dissipation.

The IHSM4825EB270L fixed inductor is a robust, reliable and highly efficient device for use in automotive power applications. Its shielded construction helps reduce the presence of stray electromagnetic fields across a wide range of frequencies and minimizes losses due to eddy current, while its heat resistant, magnetic material provides superior long-term stability and reliability.
