PA2670NL

Common Mode Chokes Overview

The PA2670NL is a surface-mount common mode choke manufactured by Pulse Electronics. It features a single-channel toroidal design with an inductance of 500 uH and a maximum DC current rating of 16 A. The component has a maximum DC resistance of 4.25 mOhms and operates within a temperature range of -40 C to +120 C. Physical dimensions are 31 mm length, 25.4 mm width, and 12.7 mm height. It holds AEC-Q200 qualification.

Common Mode Chokes Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High current handling capability up to 16 A
• Surface mount toroidal construction

Common Mode Chokes Applications

• Automotive electronic circuits requiring common mode noise suppression
• Power supply input filtering for high-current applications
• Signal integrity protection in automotive data lines

Common Mode Chokes Procurement Notes

Verify the specific suffix (NLT vs NL) against your bill of materials, as packaging formats differ between reel/cut tape and tube configurations. Confirm that the 16 A saturation current and 4.25 mOhm DCR meet your thermal management requirements. Ensure the PCB footprint matches the 31x25.4 mm outline. Check for RoHS compliance status if required by your assembly specifications.

Common Mode Chokes Selection Notes

Select this component when high current capacity is critical alongside common mode noise reduction. The 500 uH inductance provides significant impedance at common mode frequencies. The unshielded toroidal design may require careful placement relative to sensitive components. Consider the physical size constraints given the 12.7 mm height profile for your enclosure design.

Common Mode Chokes Part Context

This part belongs to Pulse Electronics' SMT Common Mode Chokes series, specifically grouped with models like HCCI-80 and PG1265NL. It serves as a passive filter component designed to suppress electromagnetic interference in single-ended or differential signal paths where high current flow is present without saturating the magnetic core.

Common Mode Chokes Replacement Considerations

Cross-reference with PG1265NL from the same manufacturer series for potential compatibility. Verify that any substitute maintains the 500 uH inductance and 16 A current rating. Ensure the replacement supports the -40 C to +120 C operating temperature range and fits the existing PCB land pattern.
