1ER1

Overview

The TE Connectivity Corcom Filters 1ER1 is a single-phase, two-stage EMC/EMI power line filter module designed for commercial applications. It supports an AC voltage rating of 250VAC and a current capacity of 1A at operating frequencies of 50Hz and 60Hz. The unit utilizes a chassis mount installation style with quick-connect terminals for circuit integration.

Feature Summary

• Provides two-stage filtering configuration to attenuate electromagnetic interference.
• Designed for chassis mounting to secure the component within equipment enclosures.

Applications

• Commercial electronic equipment requiring EMI suppression
• Power supply input stages in industrial devices
• General purpose signal integrity maintenance

Procurement Notes

Verify the specific datasheet version before procurement, as manufacturer documentation may be updated. Confirm that the quick-connect terminal dimensions match the target PCB or wire harness specifications. Ensure the chassis mounting hole pattern aligns with the mechanical design constraints of the host system to guarantee proper fitment.

Selection Notes

Select this model when a compact, single-phase solution is required for low-current circuits. The two-stage architecture offers enhanced noise reduction compared to single-stage alternatives. Verify that the 1A current rating meets the operational load requirements without exceeding thermal limits during continuous use.

Part Context

This component belongs to the Corcom Filters product line, which specializes in power line filters for managing electrical noise. The 1ER1 variant specifically addresses the needs of low-amperage applications where space efficiency and straightforward installation are prioritized over high-capacity performance metrics.

Replacement Considerations

Consult official manufacturer substitution lists for verified equivalents. Generic replacements may not replicate the specific two-stage filtering characteristics or terminal configurations required for proper system integration.
