Overview
The CM5740Z241B-00 is a through-hole common mode choke manufactured by Laird-Signal Integrity Products. It features four lines and is rated for a maximum current of 20A with a maximum DC resistance of 1.3mOhm. The component provides an impedance of 100 Ohms at 100 MHz and operates within a temperature range of -55°C to 125°C.
Feature Summary
- Provides effective common mode noise suppression for multi-line signal and power circuits
- Designed for high-current applications with a 20A rating and low DC resistance
- Constructed for robust through-hole mounting in industrial environments
Applications
- Industrial control systems requiring EMI filtering
- Power supply input stages for noise reduction
- Data communication lines needing common mode interference suppression
Procurement Notes
Verify the specific package configuration and pinout against the official datasheet before integration, as through-hole variants may differ from surface-mount equivalents. Confirm that the 20A current rating aligns with the thermal management capabilities of the target PCB layout to ensure reliable operation under continuous load conditions.
Selection Notes
Select this component when high current handling and multi-line filtering are required in a through-hole form factor. Ensure the operating environment stays within the specified -55°C to 125°C range. Compare the 100 Ohm impedance at 100 MHz against the target noise frequency spectrum to verify adequate attenuation performance for the specific application requirements.
Part Context
This part belongs to the CM5740 series of common mode chokes from Laird-Signal Integrity Products. The series is designed for robust electromagnetic interference filtering in demanding electronic environments. The CM5740Z241B-00 specifically utilizes a through-hole construction suitable for high-reliability assemblies where mechanical stability is prioritized over space constraints.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative Laird models such as the CM5740Z241B-10, noting potential differences in packaging or specific electrical tolerances.
