PM3700-60

Common Mode Chokes Overview

The PM3700-60 is a surface-mount common mode choke from the Bourns PM3700 series. It features an inductance of 5.0 mH minimum and a maximum DC current rating of 2 A. The component has a maximum DC resistance of 70 mOhms. Physical dimensions are 17.78 mm length, 17.78 mm width, and 11.43 mm height. It operates within a temperature range of -55°C to +125°C.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for two-line circuits
• Designed for surface mount PCB integration
• Constructed for high thermal stability across wide operating temperatures

Common Mode Chokes Applications

• Signal line filtering in electronic equipment
• Noise suppression in data transmission interfaces
• EMI reduction in power supply input stages

Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., RC) against the datasheet to confirm tape and reel packaging details. Ensure the manufacturer part number matches the required inductance tolerance and current ratings. Cross-reference the footprint dimensions with the design layout to guarantee compatibility with the intended PCB assembly process.

Common Mode Chokes Selection Notes

Select this component when a 5.0 mH inductance value is required for common mode noise attenuation. Verify that the 2 A current rating meets the circuit's operational demands without saturation. Check that the 70 mOhm DCR aligns with voltage drop constraints. Confirm the SMD package size fits the available board space.

Common Mode Chokes Part Context

This component belongs to the PM3700 series of SMD common mode chokes manufactured by Bourns. The series offers various inductance values tailored for different filtering requirements. These components are designed to replace through-hole equivalents in compact modern electronics designs requiring reliable EMI performance.

Common Mode Chokes Replacement Considerations

Check the PM3700-50-RC for lower inductance needs or the PM3700-70-RC for higher inductance options within the same series. Ensure any substitute maintains the 17.78 x 17.78 mm footprint and similar current handling capabilities.
