Procurement Notes

Verify the specific voltage rating (115V or 250V) required for your application against the datasheet specifications. Confirm that the quick connect terminal type matches your existing harness or PCB layout. Ensure the chassis mounting dimensions are compatible with your enclosure design before finalizing procurement.

Selection Notes

Select this component when a single-phase, two-stage EMI filter is needed for 3A applications. Consider the operating temperature range of -25°C to 100°C for environmental compatibility. Evaluate the physical size constraints to ensure the chassis mount form factor fits within the available space in the target device.

Part Context

This part belongs to the Qualtek 854 series of power line filters. The series offers various configurations for different current and voltage requirements. The 854-03/003 specifically addresses standard single-phase AC line filtering needs with a robust construction suitable for industrial and commercial environments.

Replacement Considerations

Check for direct substitutes within the Qualtek 854 series that match the 3A rating and two-stage topology. Verify that any alternative component maintains the same quick connect termination style and chassis mounting footprint to avoid redesigning the mechanical assembly.
