CMF65-5003SM

Common Mode Chokes Overview

The CMF65-5003SM is a surface mount common mode transformer choke manufactured by Gowanda Electronics. It features an inductance of 500 µH at 10 kHz with a tolerance of ±25%. The component supports a rated current of 3.6 A and exhibits a DC resistance (DCR) of 23 mΩ per winding. Designed for non-standard SMT packages, it operates within a temperature range defined by a 50°C rise from a 75°C ambient baseline. This leaded version is intended for commercial off-the-shelf applications requiring robust common mode noise suppression.

Common Mode Chokes Feature Summary

• Surface mount construction for automated assembly integration
• Common mode transformer choke topology for differential noise rejection
• High current handling capability suitable for power line filtering

Common Mode Chokes Applications

• Power supply input filtering
• Data line noise suppression
• EMI reduction in industrial equipment

Common Mode Chokes Procurement Notes

Verify the specific suffix 'SM' indicates leaded composition versus 'SMLF' for RoHS compliance when sourcing. Confirm package dimensions against PCB footprint requirements as the series uses non-standard footprints. Ensure thermal management accounts for the specified temperature rise parameters during operation to maintain performance integrity.

Common Mode Chokes Selection Notes

Select this component when high inductance values are required in a compact surface mount form factor. Compare DCR specifications against other series members to balance conduction losses with physical size constraints. Validate that the 3.6 A current rating aligns with the maximum operational load of the target circuit without saturation.

Common Mode Chokes Part Context

This part belongs to the CMF65SM series of SMT common mode transformer chokes. The series offers various inductance and current combinations tailored for different power levels. Gowanda Electronics designs these components for demanding environments, leveraging internal testing facilities to ensure reliability across aerospace, defense, and medical sectors.

Common Mode Chokes Replacement Considerations

The CMF65-5003SMLF serves as the primary alternative, offering identical electrical characteristics but with lead-free manufacturing. Verify pin compatibility and mechanical fit before substitution.
