CTSFW7040F-4R7M

Fixed Inductors Overview

The CTSFW7040F-4R7M is a surface-mount flat wire power inductor from Central Technologies. It features an inductance of 4.7 µH with a tolerance of ±20%. The component has a maximum DC resistance (DCR) of 30 mΩ. It supports a saturation current (Isat) of 7.96 A and an RMS current (Irms) rating defined by a core surface temperature rise within 50°C.

Fixed Inductors Feature Summary

• Utilizes flat wire construction for enhanced power density
• Provides shielded design to minimize electromagnetic interference
• Ensures stable switching characteristics under high load conditions

Fixed Inductors Applications

• High-power motor control cabinets
• Power supply input filtering stages
• DC-DC converter output smoothing

Fixed Inductors Procurement Notes

Verify the specific ordering suffix matches the required inductance value of 4.7 µH and tolerance class. Confirm that the package dimensions align with the footprint requirements of the target PCB layout. Ensure compliance with RoHS standards if environmental regulations apply to the final assembly process.

Fixed Inductors Selection Notes

Select this component when high current handling capability is required alongside compact surface-mount integration. The flat wire technology offers lower AC losses compared to traditional round wire alternatives. Evaluate thermal management needs based on the specified Irms rating and ambient operating temperatures.

Fixed Inductors Part Context

This part belongs to the CTSFW7040F series of fixed power inductors. The series is designed for applications demanding robust performance in space-constrained environments. It complements other components in power conversion circuits by providing reliable energy storage and noise suppression.

Fixed Inductors Replacement Considerations

Direct substitutes include parts with identical 4.7 µH inductance, similar current ratings, and compatible SMD footprints. Verify DCR and Isat specifications match or exceed original requirements to maintain circuit stability.
