• Constructed for robust through-hole PCB integration
• Engineered to handle high current loads up to 4 A

Applications

• Power supply input filtering
• EMI suppression in AC/DC converters
• Industrial equipment power stages

Procurement Notes

Verify the specific datasheet version for the 744866692 to confirm mechanical tolerances and thermal derating curves. Ensure the selected supplier provides traceability documentation compliant with industry standards. Cross-reference the 68 mΩ DCR specification against system loss requirements before finalizing procurement orders.

Selection Notes

Select this component when high current handling capability is required alongside significant common mode attenuation. The 6.9 mH value offers effective filtering for lower frequency noise profiles. Evaluate the 37x26x45 mm footprint against available board space constraints during the initial design phase.
