849-10/003

Overview

The Qualtek 849-10/003 is a single-phase EMI/EMC power line filter designed for flange mounting. It operates at 50 Hz or 60 Hz with a current rating of 10 A and voltage ratings up to 250 VAC. The unit features quick-connect terminals and provides two-stage filtering to suppress electromagnetic interference in equipment with low RF impedance.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Flange mount design for secure chassis installation
• Quick-connect terminal configuration for simplified wiring

Applications

• Industrial control systems requiring EMI suppression
• Medical equipment needing compliant power line filtering
• Test and measurement instruments sensitive to RF noise

Procurement Notes

Verify the specific voltage and current requirements against the datasheet before procurement. Confirm that the flange mounting dimensions match the intended enclosure. Ensure the quick-connect terminals are compatible with the available harness connectors. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when low RF impedance equipment requires robust two-stage attenuation. The 10 A rating suits moderate power applications. Verify that the 250 VAC rating aligns with the local mains supply. Consider the physical size constraints due to the flange mount style.

Part Context

This part belongs to the Qualtek 849 Series of power line filters. These components are engineered for general-purpose EMI suppression in AC power inputs. The series offers various current ratings and mounting options to accommodate diverse electronic equipment standards.

Replacement Considerations

Consult official Qualtek documentation for direct cross-references. Verify that any substitute maintains the same two-stage topology and flange mounting interface. Ensure electrical ratings meet or exceed the original 10 A and 250 VAC specifications.
