CM1011R-105

Overview

The Delevan CM1011R-105 is a horizontal through-hole common mode choke designed for PCB mounting. It features an epoxy potted construction and provides an inductance of 1 mH with a tolerance of +/- 25%. The component supports a maximum DC current of 1 A and exhibits a maximum DC resistance of 18 milliohms. Its physical dimensions are 27.94 mm in length, 27.94 mm in width, and 17.78 mm in height.

Feature Summary

• Horizontal PC mount configuration suitable for standard printed circuit board assembly
• Epoxy potted housing provides environmental protection and mechanical stability
• Unshielded design allows for flexible layout integration in signal paths

Applications

• Common mode noise suppression in electronic circuits
• Signal line filtering in communication equipment
• Power supply input filtering for noise reduction

Procurement Notes

Verify the specific suffix and manufacturing date code upon order confirmation to ensure alignment with current production standards. Confirm that the horizontal mounting orientation matches the target PCB footprint requirements. Check RoHS compliance documentation if restricted substance regulations apply to the final assembly process.

Selection Notes

Select this component when a horizontal form factor is required for space-constrained PCB layouts. The low DC resistance minimizes voltage drop in power lines. Ensure the operating current remains below the 1 A rating to prevent saturation or thermal issues. Verify that the unshielded nature does not interfere with nearby sensitive components.

Part Context

This part belongs to the CM1011R series of common mode chokes manufactured by API Delevan. The series is characterized by epoxy potting and horizontal mounting styles. It serves as a passive filter component within the broader category of inductors and chokes used for electromagnetic interference mitigation.

Replacement Considerations

Direct substitutes include other horizontal epoxy-potted common mode chokes with matching 1 mH inductance and similar current ratings. Verify pin spacing and overall envelope dimensions before substitution to ensure mechanical compatibility.
