CLS125NP-750NC

Fixed Inductors Overview

The CLS125NP-750NC is a surface-mount power inductor from the Sumida CLS125 series, featuring a ferrite core and wirewound construction. It offers an inductance of 75 µH with a tolerance of ±30%. The component supports a maximum DC current of 1.78 A and a saturation current of 1.8 A, with a maximum DC resistance of 365 mΩ. Designed for operation between -40°C and +105°C, it utilizes four terminal pins to enable flexible circuit configurations.

Fixed Inductors Feature Summary

• Four-terminal pin configuration allows versatile design options as standard inductors or coupled components
• Capable of functioning as a coupled inductor, parallel single inductors, 1:1 transformer, or autotransformer
• Optimized for high-efficiency up-down DC-DC converter topologies such as SEPIC and Zeta converters

Fixed Inductors Applications

• SEPIC converter circuits
• Zeta converter applications
• High-efficiency up-down DC-DC converters
• Coupled inductor implementations
• Autotransformer designs

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation when sourcing, as Sumida America Components Inc. may distribute products under the broader Sumida Corporation brand identity. Confirm that the four-terminal package matches the required footprint for coupled inductor or transformer configurations. Ensure the ferrite core material and wirewound construction align with the thermal and magnetic requirements of the target power supply topology.

Fixed Inductors Selection Notes

Select this component when a four-terminal SMD inductor is required for complex power stages like SEPIC or Zeta converters. The 75 µH value and 1.78 A rating suit moderate power applications. The unshielded design requires careful layout consideration for electromagnetic interference. Verify that the 365 mΩ DCR meets efficiency targets for the specific load current conditions.

Fixed Inductors Part Context

This part belongs to the CLS125 series, characterized by its unique four-terminal structure. Unlike standard two-terminal inductors, this series supports advanced magnetic coupling applications. It serves as a critical passive component in modern power management ICs requiring bidirectional energy transfer or isolated conversion stages within compact surface-mount footprints.
