Common Mode Chokes Procurement Notes

Verify the specific datasheet revision to confirm mechanical dimensions and electrical tolerances before integration. Ensure the selected variant matches the required lead pitch and pin configuration for the target PCB layout. Confirm that the operating temperature range aligns with the environmental conditions of the final application. Cross-reference the manufacturer's obsolescence status to assess long-term availability risks.

Common Mode Chokes Selection Notes

Select this component when a high-inductance common mode choke is required for low-current signal or power lines. The 200 mA rating limits suitability to low-power applications. Verify that the 5.4 Ohm DC resistance does not introduce excessive voltage drop in the circuit path. Ensure the physical footprint accommodates the vertical orientation and specified lead spacing.
