Overview
The Delevan CM6350R-684 is a surface-mount common mode choke designed for PCB integration. It features an inductance of 680 uH with a tolerance of 25%. The component supports a maximum DC current of 1.2 A and exhibits a maximum DC resistance of 90 mohms. Its physical dimensions are 0.36 inches in length, 0.36 inches in width, and 0.2 inches in height. The device operates within a temperature range of -55 C to +105 C and is supplied in bulk packaging.
Feature Summary
- Provides common mode noise suppression via dual-line SMD architecture
- Engineered for high thermal stability across extended industrial temperature ranges
- Optimized low DC resistance minimizes power loss in signal paths
Applications
- High-speed data line filtering
- USB interface noise reduction
- Ethernet port signal integrity protection
Procurement Notes
Verify the specific suffix and RoHS status directly with API Delevan or authorized distributors before ordering. Confirm that the bulk packaging format aligns with your assembly equipment capabilities. Ensure the 1.2 A current rating meets your circuit requirements to prevent saturation. Cross-reference the datasheet revision date to guarantee compatibility with your design specifications.
Selection Notes
Select this component when a compact SMD footprint is required for EMI mitigation on differential pairs. The 680 uH value targets specific frequency attenuation needs. Compare the 1.2 A saturation limit against peak operational currents. Consider the unshielded construction if magnetic coupling with adjacent components is a concern during layout.
Part Context
This part belongs to the CM6350R series of surface-mount common mode chokes from API Delevan. The series offers various inductance values tailored for different filtering applications. The CM6350R-684 specifically addresses mid-range inductance requirements for consumer and industrial electronics.
Replacement Considerations
Consult API Delevan documentation for direct cross-references. Verify pinout compatibility and mechanical dimensions before substituting with other manufacturers' parts.
