850-10/003

Overview

The Qualtek 850-10/003 is a single-phase EMI/EMC power line filter rated for 10 A at 115 V or 250 V AC. It operates at 50/60 Hz and features a two-stage design providing high insertion loss for both line-to-line and line-to-ground interference. The unit utilizes quick connect terminals and complies with UR, CSA, and VDE standards. Leakage current ranges from 0.50 to 1 mA, and it functions within a temperature range of -25°C to 85°C.

Feature Summary

• Two-stage architecture delivering high insertion loss across the frequency spectrum
• Effective attenuation for both line-to-line and line-to-ground noise
• Quick connect terminal interface for simplified installation

Applications

• Industrial equipment requiring EMC compliance
• Single-phase power supply input filtering
• Electronic devices sensitive to conducted emissions

Procurement Notes

Verify exact specifications against the official product datasheet before procurement. Confirm that the voltage rating of 115 V or 250 V matches your system requirements. Ensure the 10 A current rating accommodates peak loads. Check compliance certifications (UR, CSA, VDE) against regional regulatory needs. Validate leakage current limits if safety isolation is critical.

Selection Notes

Select this component when a single-phase solution is required for moderate current applications up to 10 A. The two-stage design is suitable for environments demanding significant conducted noise reduction. Ensure the operating temperature range of -25°C to 85°C aligns with the deployment environment. Verify physical dimensions and terminal type compatibility with existing PCB or chassis layouts.
