Common Mode Chokes Procurement Notes

Verify the specific suffix N6 against official STMicroelectronics documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB layout dimensions for the uQFN-6 package. Cross-reference operating temperature ranges with system requirements. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement decisions.

Common Mode Chokes Selection Notes

Select this component when designing high-speed differential links requiring combined EMI filtering and ESD protection. The 250 fF capacitance value supports signal integrity preservation at relevant frequencies. Consider the 1.4 x 1.35 mm package size for dense board layouts. Validate thermal performance across the specified -55°C to +125°C operational range for the intended environment.

Common Mode Chokes Part Context

This part belongs to STMicroelectronics' ECMF portfolio, which targets smartphone and mobile platform applications.
