Overview
The Qualtek 849-03/001 is a single-phase, two-stage EMI line filter designed for chassis mounting. It operates at rated voltages of 115 VAC and 250 VAC with a current rating of 3 A at 50/60 Hz. The unit features quick-connect terminals for installation. Electrical specifications include a maximum leakage current ranging from 0.45 mA to 0.90 mA. The filter complies with UR, CSA, and VDE safety standards.
Feature Summary
- Two-stage filtering architecture optimized for low RF impedance equipment
- Chassis mount design with quick connect terminals
- Compliance with UR, CSA, and VDE safety certifications
Applications
- Single-phase AC power line noise reduction
- Equipment with low RF frequency impedance
- Chassis-mounted electronic assemblies requiring EMC compliance
Procurement Notes
Verify the specific voltage rating (115 VAC or 250 VAC) required for your application against the datasheet. Confirm that the 3 A current rating meets system demands. Ensure chassis mounting space accommodates the physical dimensions. Check terminal compatibility for quick-connect interfaces before ordering.
Selection Notes
Select this component when low RF impedance loads are present, as the two-stage design addresses these conditions effectively. Compare leakage current limits against sensitive equipment requirements. Verify that the single-phase configuration matches the power supply infrastructure. Ensure the chassis mount style fits the enclosure constraints.
Part Context
This part belongs to the Qualtek 849 Series, which consists of two-stage filters intended for scenarios where equipment impedance at radio frequencies is low. The series provides enhanced attenuation compared to single-stage alternatives in specific impedance environments.
Replacement Considerations
Consult official manufacturer substitution lists for verified equivalents. Generic replacements may not match the two-stage topology or leakage current specifications required for low RF impedance applications.
FAQ
