851-10/009

Overview

The Qualtek 851-10/009 is a single-phase EMC/EMI power line filter module designed for chassis mounting. It operates at rated AC voltages of 115V and 250V with a current rating of 10A. The component supports frequencies of 50Hz and 60Hz and functions within an operating temperature range of -25°C to 85°C. It features quick connect termination style and utilizes a threaded post (8-32) configuration. The unit is certified under UR, CSA, and VDE standards.

Feature Summary

• Single-stage filtering configuration for electromagnetic interference suppression
• Chassis mount design with threaded post attachment
• Compliance with international safety certifications including UL, CSA, and VDE

Applications

• Industrial equipment power supply input stages
• Medical device power conditioning
• Commercial appliance noise reduction

Procurement Notes

Verify the specific datasheet revision and certification marks (UR, CSA, VDE) directly from the manufacturer's official documentation before integration. Confirm that the quick connect termination style matches the system wiring requirements. Ensure the chassis mounting dimensions and threaded post specifications align with the mechanical enclosure design to guarantee proper physical installation and electrical grounding.

Selection Notes

Select this component when a single-phase, 10A rated line filter is required for 115V or 250VAC systems. The choice depends on the need for chassis mounting rather than PCB mounting. Consider the operating temperature range of -25°C to 85°C against the environmental conditions of the target application. Verify that the quick connect termination style is compatible with existing harnesses.

Part Context

This part belongs to the Qualtek 851 series of power line filter modules. The series offers various current ratings and voltage configurations for single-phase applications. The 851-10/009 specifically addresses the 10A requirement with dual voltage capability. It is designed for robust industrial and commercial environments requiring certified EMI suppression.

Replacement Considerations

Consult official Qualtek documentation for direct cross-reference part numbers. Ensure any substitute maintains the same 10A current rating, 115V/250VAC voltage ratings, and chassis mounting form factor. Verify that alternative components hold equivalent UR, CSA, and VDE certifications for regulatory compliance.
