Overview
CM0805A371R-10 is a two-line common mode choke from Laird-Signal Integrity Products, designed for surface mount installation in the 0805 (2012 metric) package. It provides an impedance of 370 Ohms at 100 MHz with a maximum rated current of 100 mA and a DC resistance of 500 mOhms. The component operates within a temperature range of -40°C to +125°C and measures 2.00 mm in length by 1.25 mm in width.
Feature Summary
- Dual-line configuration for common mode noise suppression
- Compact 0805 surface mount footprint
- High impedance performance at 100 MHz
Applications
- Signal line filtering
- Data bus protection
- EMI suppression in compact electronics
Procurement Notes
Verify the manufacturer part number CM0805A371R-10 against official Laird datasheets to confirm the two-line common mode specification. Ensure the selected variant matches the required 370 Ohm impedance at 100 MHz and 100 mA current rating. Confirm RoHS compliance status and packaging type prior to ordering.
Selection Notes
Select this component when dual-channel common mode noise attenuation is required in space-constrained designs. The 0805 package allows for high-density PCB layouts. Verify that the 100 mA current rating meets the circuit's operational requirements and that the 500 mOhm DCR does not introduce excessive voltage drop.
Part Context
This component belongs to the CM series of common mode chokes from Laird-Signal Integrity Products. These components are engineered for signal integrity applications where differential signals must be protected from common mode interference. The series offers various impedance values and current ratings in standardized surface mount packages.
Replacement Considerations
Check for direct substitutes with identical 370 Ohm @ 100 MHz impedance and 100 mA rating in the 0805 package. Ensure replacement parts maintain the two-line configuration and compatible thermal characteristics.
