Overview
The CM0805D900R-10 is a two-line common mode choke manufactured by Laird-Signal Integrity Products. It features an unshielded surface mount design in an 0805 package (2.00mm x 1.20mm x 1.20mm). The component provides 90 Ohms impedance at 100 MHz with a maximum DC current rating of 400 mA and a maximum DC resistance of 300 mOhms. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Provides common mode noise suppression for differential signal lines
- Unshielded construction suitable for standard PCB layouts
- Compact 0805 surface mount footprint for space-constrained designs
Applications
- High-speed data interface filtering
- USB port noise suppression
- HDMI signal line protection
Procurement Notes
Verify the manufacturer designation, as some listings attribute this part to Qnity while official documentation identifies Laird-Signal Integrity Products as the source. Confirm RoHS compliance status and ensure the specific suffix matches the required impedance and current ratings for your circuit design requirements.
Selection Notes
Select this component when differential line filtering is required in a compact form factor. Ensure the 400 mA current rating meets the operational load of the target interface. Verify that the unshielded nature does not interfere with nearby sensitive components or require additional spacing on the PCB layout.
Part Context
This component belongs to the CM series of common mode chokes from Laird-Signal Integrity Products. It is designed for electromagnetic interference filtering in high-density electronic assemblies. The 0805 package size allows for automated surface mount assembly processes.
