850-20/004

Overview

The Qualtek 850-20/004 is a single-phase EMC/EMI power line filter module designed for chassis-mount applications. It features a two-stage filtering architecture providing high insertion loss for both line-to-line and line-to-ground interference across the frequency spectrum. The unit is rated for a continuous current of 20 A at operating voltages of 115 VAC and 250 VAC, with a standard frequency range of 50/60 Hz. It utilizes quick-connect terminals for electrical interfacing and is constructed to meet RoHS3 compliance standards.

Feature Summary

• Two-stage filtering design ensures high insertion loss for comprehensive EMI suppression
• Quick-connect terminal configuration facilitates rapid installation and wiring
• Chassis-mount form factor supports secure integration into power entry systems

Applications

• Chassis-mount power entry modules
• Single-phase AC power line filtering
• EMC/EMI suppression in industrial equipment

Procurement Notes

Verify exact specifications against the official product datasheet before procurement. Confirm that the 20 A rating aligns with system requirements, as some sources may list conflicting values. Ensure compatibility with 115 VAC or 250 VAC input voltages and 50/60 Hz frequencies. Check for RoHS3 compliance if required by regulatory standards. Validate terminal type and mounting dimensions for mechanical fit.

Selection Notes

Select this component for applications requiring robust single-phase EMI filtering with a 20 A capacity. The two-stage design offers superior attenuation compared to single-stage alternatives. Ensure the chassis-mount style fits the enclosure constraints. Verify voltage ratings match the specific AC supply network. Consider the quick-connect interface for ease of assembly during manufacturing.

Part Context

This part belongs to the Qualtek 850 Series, which comprises multi-purpose EMI filters. The series is characterized by its ability to provide effective noise reduction in single-phase AC circuits. The 850-20/004 variant specifically denotes the 20 A current rating within this family of power line filter modules.

Replacement Considerations

Consult official substitution guides for verified equivalents. Generic replacements must match the 20 A current rating, 250 VAC voltage rating, and single-phase configuration. Ensure any substitute maintains the two-stage filtering topology and chassis-mount form factor to preserve performance and mechanical compatibility.
