Overview
The Delevan CM1011R-254 is a horizontal PC mount common mode choke featuring epoxy potting. It provides an inductance of 250 uH with a tolerance of +/- 25%. The component supports a maximum DC current of 3.8 A and has a maximum DC resistance of 60 mOhms. Measuring 1.1 inches in length, 1.1 inches in width, and 0.7 inches in height, it utilizes SMD/SMT termination for PCB mounting.
Feature Summary
- Horizontal PCB mounting configuration
- Epoxy potted construction for environmental protection
- Unshielded ferrite core design
Applications
- Common mode noise suppression in electronic circuits
- EMI filtering for power supply lines
- Signal integrity enhancement in data transmission paths
Procurement Notes
Verify the specific suffix codes against the manufacturer datasheet to confirm exact electrical tolerances and physical dimensions. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure the selected packaging format matches the assembly requirements. Cross-reference the part number with official API Delevan documentation to validate availability and lead times.
Selection Notes
Select this component when a horizontal form factor is required for space-constrained PCB layouts. The epoxy potting makes it suitable for environments requiring vibration resistance and moisture protection. Verify that the 3.8 A current rating meets the circuit's operational demands. Consider the unshielded nature if magnetic coupling with nearby components is a concern.
Part Context
This component belongs to the CM1011R series of common mode chokes manufactured by API Delevan. The series is characterized by horizontal mounting styles and epoxy potting. Other variants in this family include models with different inductance values such as CM1011R-175 and CM1011R-504, offering a range of filtering options within the same physical footprint.
Replacement Considerations
Direct substitutes within the CM1011R series include CM1011R-175 and CM1011R-504. These parts share the same horizontal mounting style and epoxy potted construction but differ in inductance values. Verify compatibility with existing PCB footprints and thermal management requirements before substitution.
