The SM Series Normal Mode Coil is ideal for noise filters in automotive and industrial equipment.

The 1-turn structure causes very low DC Resistance (DCR), which allows the coil to withstand large currents. The iron-based amorphous core helps achieve excellent operational stability even in high-temperature environments. This component is ideal for products where safety is the primary concern.

Recommended Application

  • Automotive Equipment
    (Electronic Power Steering EPS, Electronic Oil Pump EOP, Electronic Water Pump EWP, Brake Control Circuits, Various motor noise countermeasures)

  • Industrial Equipment



Position of the Series

The SM series achieves high reliability and safety from its 1-turn structure.

This unique structure suppresses magnetic flux leakage to the minimum, preventing the malfunction of nearby circuits when high-voltage spike noise is applied.
 

Blocking Radiated Noise from Leakage Flux


Key Technologies and Advantages

  • For Automotive Applications
    Operating Temperature Range: -40 to +150℃
    Vibration Resistance: Supports 300m/s² Max Acceleration
    (There are separate detailed conditions for vibration resistance. Please contact us in advance.)

  • Withstands Large Currents
    Supports continuous 20 to 50 A and instantaneous up to 100 A. High output is possible with little voltage drop.

  • No Layer Short Circuits
    The 1-turn structure does not allow layer short circuits between windings.
