Procurement Notes

Verify the specific suffix (e.g., LF) required for lead-free compliance if mandated by your assembly process. Confirm that the bulk packaging format aligns with your manual or automated insertion capabilities. Ensure the 25 A current rating meets the peak load requirements of your target circuit design before finalizing procurement.

Selection Notes

Select this component when a high-current EMI solution is required for chassis-mounted applications. The 3000 pF capacitance offers a balance between noise attenuation and signal coupling considerations. Verify that the physical dimensions fit the available panel cutout space and that the terminal configuration matches the board layout constraints.
