CMF3-1003SMLF

Common Mode Chokes Overview

The CMF3-1003SMLF is a surface-mount common mode choke manufactured by Gowanda Electronics. It features an inductance of 100 µH measured at 1 kHz and supports two lines. The component has a maximum current rating of 7.7 A and a DC resistance (DCR) of 12 mOhm. It utilizes a horizontal package with four PC pads for mounting.

Common Mode Chokes Feature Summary

• Surface mount configuration with horizontal orientation
• Dual-line common mode filtering capability
• High current handling capacity

Common Mode Chokes Applications

• Power supply input filtering
• Data line noise suppression
• EMI reduction in electronic circuits

Common Mode Chokes Procurement Notes

Verify the specific suffix SMLF against official Gowanda documentation to confirm lead-free status and packaging details. Ensure the 7.7A rating aligns with thermal management requirements in the final assembly. Cross-reference the 12mOhm DCR value with system power loss calculations.

Common Mode Chokes Selection Notes

Select this component when high current handling is required alongside common mode noise suppression. The low DC resistance minimizes power loss in high-current paths. Verify that the surface-mount footprint fits the PCB layout constraints and that the operating temperature range meets environmental specifications.
