Overview
The CM0805C181R-10 is a common mode filter choke manufactured by Laird-Signal Integrity Products. It features an 0805 (2012 metric) surface-mount package with dimensions of 2.00mm length, 1.25mm width, and a maximum height of 1.2mm. The component provides an impedance of 180 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 400 mOhms. The device operates within a temperature range of -40°C to +125°C.
Feature Summary
- Provides common mode noise suppression for power and signal lines
- Designed for surface-mount PCB integration in compact layouts
- Capable of handling specified DC currents without saturation
Applications
- Power line filtering
- Low-frequency signal line protection
- High-frequency signal line protection
Procurement Notes
Verify the manufacturer part number against official Laird-Signal Integrity Products documentation to ensure authenticity. Confirm that the component meets RoHS3 compliance requirements for your specific project regulations. Check datasheets for updated availability status as distribution channels may vary. Ensure compatibility with your assembly process regarding moisture sensitivity levels.
Selection Notes
Select this component when common mode noise attenuation is required on single-ended lines. The 0805 footprint suits space-constrained designs. Evaluate the 300 mA current rating against peak load requirements. Consider the 180 Ohm impedance at 100 MHz relative to the target noise spectrum. Verify thermal performance within the -40°C to +125°C operating range.
Part Context
This component belongs to the CM series of common mode chokes from Laird-Signal Integrity Products. These devices are engineered for EMI suppression in electronic circuits. The series offers various impedance values and current ratings within standardized surface-mount packages to facilitate design flexibility across different form factors and noise environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official distributor databases or manufacturer cross-reference tools for potential alternatives. Ensure any replacement matches the 0805 footprint, impedance characteristics, and current handling capabilities.
