Overview
The CM5441Z161B-10 is a common mode choke manufactured by Laird-Signal Integrity Products. It features a through-hole mounting type and operates within a temperature range of -40°C to +125°C. The component provides an impedance of 160 Ohms at 100 MHz with a maximum DC current rating of 75A. Its maximum DC resistance (DCR) is specified as 0.3 milliohms. The device is classified under the CM series and utilizes a bulk packaging format.
Feature Summary
- Provides common mode noise filtering for power lines
- Supports high current applications up to 75A
- Designed for through-hole PCB mounting
Applications
- Power line EMI filtering
- Industrial automation systems
- Automotive electronics
Procurement Notes
Verify the specific impedance value against official datasheets, as sources indicate variations between 100 Ohms and 160 Ohms at 100 MHz. Confirm the manufacturer designation, noting discrepancies between Laird and Qnity in available listings. Ensure the through-hole package and 75A current rating align with design requirements before procurement.
Selection Notes
Select this component for circuits requiring robust common mode suppression with high current handling capabilities. The low DCR minimizes power loss in high-current paths. Verify thermal management needs given the 75A rating and operating temperature limits. Ensure mechanical compatibility with through-hole assembly processes and PCB layout constraints.
Part Context
This part belongs to the CM series of common mode chokes from Laird-Signal Integrity Products. These components are engineered for electromagnetic interference filtering in signal integrity and power distribution networks. The series typically offers various impedance and current ratings to suit different electronic system requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching impedance, current rating, and package dimensions with alternative manufacturers' common mode chokes.
