Overview
The Delevan CM6460R-755 is a surface-mount common mode choke designed for PCB integration. It features an inductance of 7500 uH with a tolerance of ±25%. The component supports a maximum DC current of 440 mA and exhibits a maximum DC resistance of 640 mOhms. Physical dimensions are 13.46 mm in length, 13.46 mm in width, and 7.37 mm in height. It operates within a temperature range of -55°C to +105°C and utilizes ferrite core material without shielding.
Feature Summary
- Surface mount configuration for automated PCB assembly
- Ferrite core construction for effective noise suppression
- Unshielded design suitable for standard electromagnetic environments
Applications
- Common mode noise filtering in electronic circuits
- Signal integrity protection in data transmission lines
- Power supply input filtering applications
Procurement Notes
Verify the specific suffix 'R' against the manufacturer's official documentation to confirm surface-mount compatibility and lead frame specifications. Ensure that the 640 mOhms DC resistance value aligns with thermal management requirements for the target 440 mA operating current. Confirm RoHS compliance status through the latest datasheet revision, as regulatory markings may vary by production batch.
Selection Notes
Select this component when high inductance is required for low-frequency common mode noise attenuation in space-constrained designs. The surface-mount package facilitates automated placement processes compared to through-hole alternatives. Evaluate the 440 mA current rating against peak load conditions to prevent saturation. Consider the unshielded nature of the device regarding proximity to sensitive signal traces or other magnetic components on the board layout.
Part Context
This part belongs to the CM6460R series of common mode chokes manufactured by Delevan. The series offers various inductance values tailored for different noise filtering frequencies. The CM6460R variant specifically denotes surface-mount technology, distinguishing it from the through-hole CM6460 or CM7560 series. These components are categorized under passive filters and inductors used for electromagnetic interference mitigation.
