The component has a low maximum DC resistance of 6 mΩ. It is designed for two-line applications with SMD/SMT termination. Operating temperature ranges from -55 °C to +125 °C. Physical dimensions are 21.6 mm length, 11.43 mm width, and 11.43 mm height.

Common Mode Chokes Feature Summary

• Surface-mount construction for automated PCB assembly
• High current handling capability up to 7 A
• Low DC resistance for minimal power loss
• Wide operating temperature range suitable for harsh environments

Common Mode Chokes Applications

• Data line filtering
• Signal integrity protection
• EMI suppression in electronic circuits

Common Mode Chokes Procurement Notes

Verify the specific inductance tolerance and current rating against the official Bourns datasheet before procurement. Confirm package dimensions match the PCB footprint. Ensure RoHS compliance status aligns with project requirements. Check for any recent product change notices that may affect specifications or availability.

Common Mode Chokes Selection Notes

Select this component when high current capacity and low resistance are required for common mode noise reduction. Compare inductance values with other PM3700 variants like the PM3700-50-RC if higher impedance is needed. Consider physical size constraints as the package is relatively large compared to standard chip inductors.

Common Mode Chokes Part Context

The PM3700 series consists of unshielded surface-mount common mode chokes manufactured by Bourns Inc. These components are part of the broader portfolio acquired from J.W. Miller Magnetics. The series offers various inductance options to suit different filtering requirements while maintaining a consistent form factor for design flexibility.

Common Mode Chokes Replacement Considerations

Direct substitutes include other PM3700 series parts such as PM3700-40-RC or PM3700-70-RC, depending on required inductance. Verify pinout and mechanical dimensions match before substitution.
