Common Mode Chokes datasheet and documents for CMCC0805181ST
Common Mode Chokes Overview
The CMCC0805181ST is a surface-mount common mode choke manufactured by Venkel. It features a two-line configuration with an impedance of 180 Ohms at 100 MHz and a rated current of 330 mA. The component utilizes a horizontal package with four pad connections and exhibits a DC resistance (DCR) of 350 milliohms.
Common Mode Chokes Feature Summary
- Provides common mode noise suppression for differential signal lines
- Designed for high-frequency applications with specified impedance characteristics
- Utilizes a compact surface-mount form factor suitable for automated placement
Common Mode Chokes Applications
- High-speed data interface protection
- Signal line filtering in electronic circuits
- Noise suppression in compact electronic assemblies
Common Mode Chokes Procurement Notes
Verify the specific impedance value at 100 MHz and the continuous current rating of 330 mA against design requirements. Confirm the DCR specification of 350 milliohms to ensure compatibility with power budget constraints. Ensure the horizontal four-pad package footprint matches the PCB layout. Validate RoHS compliance status if required by project specifications.
Common Mode Chokes Selection Notes
Select this component when a low-profile, two-line choke is needed for frequencies around 100 MHz. The 330 mA current rating suits low-power signal lines. Consider the 350 milliohm DCR impact on signal integrity. The 0805 size offers a balance between performance and board space efficiency for dense layouts.
Common Mode Chokes Part Context
