Overview
The ED101-1.25-7M0 is a current-compensated common mode choke from the Schaffner ED101 series, designed for lighting applications. It features a ferrite core and through-hole PCB mounting with four pins. Key electrical parameters include an inductance of 7 mH at 10 kHz, a maximum DC current rating of 1.25 A, and a maximum DC resistance of 400 mOhms (typical) or 600 mOhms (maximum). The component operates within a temperature range of -40°C to +125°C and has dimensions of 24 mm x 14.3 mm x 15.3 mm.
Feature Summary
- Current-compensated design optimized for single-phase power line filtering
- Ferrite core construction for effective electromagnetic interference suppression
- Through-hole vertical mounting configuration for secure PCB integration
Applications
- Lighting applications
- Power line filtering
- Common mode noise suppression in electronic circuits
Procurement Notes
Verify the specific datasheet version and tolerance specifications (-30%, +50%) prior to procurement, as manufacturing updates may occur. Confirm that the 4-pin through-hole package aligns with your PCB footprint requirements. Ensure the 1.25 A current rating meets the operational demands of your target circuit to prevent saturation or overheating during peak load conditions.
Selection Notes
Select this component when a compact, current-compensated choke is required for single-phase AC lines. The 7 mH inductance provides significant common mode attenuation. Verify that the 1.25 A continuous current rating suits the load. The wide operating temperature range supports diverse environmental conditions. Ensure the unshielded design does not interfere with adjacent sensitive components on the board.
Part Context
This part belongs to the Schaffner ED101 series of current-compensated chokes. These components are engineered specifically for lighting applications and general power line filtering. The series utilizes ferrite cores to manage electromagnetic interference. The ED101-1.25-7M0 represents a specific variant with defined inductance and current ratings within this broader product family.
Replacement Considerations
The ED100-1.25-7M0 is a related variant within the same manufacturer's portfolio. Verify pin compatibility and exact inductance tolerances before substitution. Ensure the replacement part meets the same thermal and current specifications for the intended application.
