Common Mode Chokes Procurement Notes
Verify the specific impedance value at 100 MHz and current rating against the official Venkel datasheet before integration. Confirm that the 50V DC voltage rating meets the circuit requirements. Ensure the operating temperature range of -40°C to 85°C aligns with the environmental conditions of the final application.
Common Mode Chokes Selection Notes
Select this component when space constraints require an 0805 package size. Choose based on the required 120 Ohm impedance at 100 MHz for effective high-frequency noise attenuation. Consider the 370 mA current limit to ensure the component does not saturate or overheat during normal operation.
Common Mode Chokes Part Context
This component belongs to the Venkel CMCC series of common mode chokes. These components are designed for surface-mount technology (SMT) applications. The 0805 designation indicates the physical case size, balancing performance with board space efficiency.
Common Mode Chokes Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Cross-reference impedance, current rating, and package dimensions to ensure functional compatibility.
