Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., DG) against the manufacturer's official documentation to confirm exact physical dimensions and marking codes. Ensure the procurement specification matches the required 2.2 A rated current and 1.6 mH inductance values. Confirm that the through-hole mounting style aligns with the target PCB design requirements before finalizing orders.

Common Mode Chokes Selection Notes

Select this component when a vertical form factor is required for space-constrained through-hole designs. The 2.2 A rating suits moderate current applications. Verify compatibility with the target PCB hole pattern and ensure the 1.6 mH inductance meets the specific EMI filtering needs of the circuit design.
