CMN3-1004VSMLF

Common Mode Chokes Overview

The CMN3-1004VSMLF is a vertical mount common mode toroidal choke manufactured by Gowanda Electronics. It features an inductance of 1000 µH and operates within a temperature range of -55°C to +150°C. The component utilizes a horizontal, 4-pin pad surface mount package configuration. Current ratings are determined based on a 60°C temperature rise at ambient conditions.

Common Mode Chokes Feature Summary

• Vertical mounting orientation for space-efficient PCB integration
• Toroidal core design for effective common mode noise suppression
• Extended high-temperature operational capability up to 150°C

Common Mode Chokes Applications

• Power supply input filtering
• Battery charger circuits
• Voltage regulation stages

Common Mode Chokes Procurement Notes

Verify the specific current rating against the official datasheet, as it depends on the 60°C temperature rise criteria. Confirm the horizontal 4-pin pad footprint matches your PCB layout requirements. Ensure the vertical mounting style is compatible with your assembly process and spatial constraints before ordering.

Common Mode Chokes Selection Notes

Select this component when high-frequency common mode noise rejection is required in compact designs. The vertical form factor aids in reducing board area usage compared to horizontal equivalents. Consider the wide operating temperature range for environments subject to thermal stress or high ambient heat during operation.

Common Mode Chokes Part Context

This part belongs to the CMN3 series of common mode chokes from Gowanda Electronics. The series includes variants such as CMN3-1005VSMLF and CMN3-2704VSMLF, offering different inductance values while maintaining similar vertical mounting and toroidal construction characteristics for consistent performance profiles.

Common Mode Chokes Replacement Considerations

Check for direct substitutes like CMN3-1005VSMLF if slightly different inductance is acceptable. Verify pinout compatibility with existing footprints. Ensure replacement parts maintain the same vertical mounting orientation and temperature rating specifications.
