Overview
The CM5740Z241B-10 is a common mode choke manufactured by Laird-Signal Integrity Products. It features an impedance of 100 Ohms at 100 MHz and supports a maximum current rating of 20A. The DC resistance (DCR) is maximized at 1.3 mOhm. The component utilizes a vertical package with 8 PC pins for through-hole mounting. Its physical dimensions are 0.570 inches in length. The operating temperature range spans from -40°C to 125°C.
Feature Summary
- Provides common mode noise filtering for multi-line circuits
- Supports high current applications up to 20A
- Utilizes a vertical through-hole mounting configuration
Applications
- High-current power line filtering
- Multi-line signal integrity protection
- EMI suppression in industrial equipment
Procurement Notes
Verify the specific impedance value against official datasheets, as conflicting public records indicate either 100 Ohms or 240 Ohms at 100 MHz. Confirm the pin count and package orientation match the design requirements. Ensure the manufacturer designation aligns with Laird-Signal Integrity Products specifications before finalizing procurement orders.
Selection Notes
Select this component when high current handling capacity near 20A is required alongside common mode noise reduction. The low DC resistance minimizes power loss in high-current paths. Verify that the through-hole mounting style fits the target PCB layout constraints and that the thermal performance meets the operational temperature range requirements.
Part Context
This part belongs to the Laird-Signal Integrity Products portfolio of EMI filters and chokes. It is designed for robust noise suppression in demanding electronic environments. The component serves as a critical element for maintaining signal integrity and reducing electromagnetic interference in power and data lines.
Replacement Considerations
Publicly available substitute part numbers were not identified in the provided documentation. Consult official manufacturer catalogs for verified cross-references.
