PM3700-30

Common Mode Chokes Overview

The PM3700-30 is a surface-mount common mode choke from the Bourns PM3700 series. It features an inductance of 750 µH at 1 kHz and supports a maximum DC current of 5.5 A. The component has a maximum DC resistance of 12 mΩ. Physical dimensions are 17.78 mm x 11.43 mm, with a height of approximately 6.35 mm. It operates within a temperature range of -55°C to +125°C.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression for differential signal lines
• Designed for high-current applications with a 5.5 A rating
• Utilizes a compact surface-mount footprint for automated PCB assembly

Common Mode Chokes Applications

• High-speed data interface filtering
• Power supply line noise reduction
• Industrial control system EMI suppression

Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., -RC) against the required packaging format such as cut tape or reel. Confirm that the 5.5 A current rating aligns with the thermal management requirements of the target application. Ensure the 12 mΩ DCR meets the voltage drop constraints of the circuit design before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 750 µH inductance value is required for common mode noise attenuation. The 5.5 A current capability makes it suitable for power delivery lines or high-current data buses. Compare the 17.78 mm x 11.43 mm package size against available board space constraints relative to other series members like the PM3700-50.

Common Mode Chokes Part Context

This part belongs to the Bourns PM3700 series of SMD common mode chokes. The series includes variants with different inductance values, such as the PM3700-10 and PM3700-50, allowing designers to tune noise suppression characteristics while maintaining consistent physical footprints and mounting styles across a product line.

Common Mode Chokes Replacement Considerations

Direct substitutes include other PM3700 series variants like PM3700-10 or PM3700-50 if inductance differences are acceptable. Cross-brand replacements require matching the 17.78 mm x 11.43 mm footprint, 5.5 A current rating, and 750 µH inductance specifications.
