851-02/002

Overview

The Qualtek 851-02/002 is a single-phase EMC/EMI line filter designed for chassis mounting. It operates at 50/60Hz with a rated AC voltage of 115V and 250V. The component supports a current rating of 2A and features a single-stage configuration. Termination is achieved via wire leads. The unit functions within a temperature range of -25°C to +85°C.

Feature Summary

• Provides electromagnetic interference suppression in single-phase power circuits
• Utilizes wire lead termination for direct connection integration
• Engineered for secure chassis installation environments

Applications

• Single-phase power supply input filtering
• Electronic equipment chassis integration
• General purpose EMI noise reduction

Procurement Notes

Verify the specific manufacturer part number against official distributor catalogs to ensure authenticity. Confirm that the wire lead configuration matches the target assembly requirements. Check for RoHS compliance status if environmental regulations apply to the final product deployment. Ensure the operating temperature range aligns with the intended application environment.

Selection Notes

Select this component when a single-stage, single-phase filter is required for low-current applications up to 2A. The wire lead design suits direct wiring rather than PCB mounting. Consider the chassis mount form factor for space-constrained enclosures. Validate that the 115V/250VAC rating meets the system voltage specifications.

Part Context

This model belongs to the Qualtek 851 series of power line filters. The series offers various current ratings and configurations for different power levels. The 851-02/002 specifically addresses lower current needs compared to higher-rated siblings like the 851-20 series. It shares the same chassis-mount architecture and certification standards as other units in the family.

Replacement Considerations

Direct substitutes include the Qualtek 851-03/003 for slightly higher current capacity. Other models in the 851 series may serve as alternatives if current or voltage requirements differ. Verify pinout and lead length compatibility before swapping.
