Common Mode Chokes Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official Venkel datasheet before finalizing the design. Confirm that the 1206 package dimensions align with the target PCB layout constraints. Ensure that the supplier provides documentation confirming RoHS compliance and material safety declarations as required by regulatory standards for electronic components.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring common mode noise rejection for differential pairs operating at frequencies around 100 MHz. Consider the 310mA current limit to ensure adequate headroom for peak signal currents. Evaluate the low DCR characteristic to maintain signal integrity without excessive voltage drop. Compare alternative packages if space constraints differ from the standard 1206 footprint.

Common Mode Chokes Part Context

The CMCC series represents Venkel's lineup of surface mount common mode chokes engineered for compact electronics. These components are part of a broader family offering various impedance levels and current ratings. The CMCC1206261MT specifically addresses applications needing moderate current handling with precise high-frequency noise suppression capabilities within a small form factor.

Common Mode Chokes Replacement Considerations

Consult official cross-reference lists or manufacturer substitution guides for verified equivalent parts. Ensure any substitute maintains identical impedance characteristics at 100 MHz and meets the 310mA current requirement. Verify package compatibility and pinout alignment to prevent PCB redesign efforts.
