Common Mode Chokes Procurement Notes

Verify the specific suffix 'MUTAG' against the official onsemi datasheet to confirm pinout and marking code compatibility. Ensure the application environment stays within the specified -40 °C to +85 °C operating temperature range. Confirm that the 3.3 V working voltage aligns with the target circuit design requirements before procurement.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require combined EMI filtering and ESD protection. The XDFN-10 package suits compact portable electronics. Consider the 2.9 pF capacitance for signals requiring minimal distortion. Verify that the 16 A peak pulse current rating meets the transient surge expectations of the specific interface standard being protected.

Common Mode Chokes Part Context

The EMI8042MUTAG belongs to the EMI804x series from onsemi, which introduces integrated common mode filters with ESD protection. This family addresses the industry need for consolidated protection solutions in high-speed digital interfaces. The series simplifies board layout by reducing component count compared to discrete filter and TVS diode combinations.
