Overview
The Delevan CM6296-304 is a surface-mount common mode choke designed for data line filtering and isolation applications. It features an inductance of 300 µH with a 25% tolerance and supports a maximum DC current of 7.5 A. The component exhibits a maximum DC resistance of 0.016 Ω (16 mΩ). Its physical dimensions are 22.1 mm in diameter and 10.74 mm in height, housed in a bulk package. The device operates within a temperature range of -55 °C to +125 °C and is classified as moisture sensitive.
Feature Summary
- Provides common mode noise suppression for differential data lines
- Functions as an isolation transformer for signal integrity
- Designed for surface-mount PCB integration
Applications
- Data line filtering
- Signal isolation circuits
- Electronic equipment requiring EMI suppression
Procurement Notes
Verify the specific suffix designation, as CM6296-304 may correspond to legacy or leaded variants distinct from the RoHS-compliant CM6296R series. Confirm moisture sensitivity handling requirements upon receipt. Ensure the supplier provides full lot documentation to validate material composition and manufacturing origin against project specifications.
Selection Notes
Select this component when a 300 µH inductance value is required for common mode noise attenuation. Verify that the 7.5 A current rating meets the circuit's operational demands. Consider the unshielded construction and bulk packaging format during layout planning. Compare against the CM6296R-304TR variant if tape-and-reel automation or RoHS compliance is mandatory.
Part Context
This part belongs to the Delevan CM6296 series of common mode chokes. The series offers various inductance values tailored for different filtering needs. The CM6296-304 specifically targets applications requiring moderate inductance with high current handling capabilities in a compact surface-mount footprint.
Replacement Considerations
The CM6296R-304TR is a documented equivalent within the same manufacturer family, offering identical electrical characteristics but potentially differing in packaging and compliance standards.
