Procurement Notes

Verify the specific voltage rating required for your application, as sources indicate both 125 V and 250 V ratings. Confirm the capacitance tolerance and exact insertion loss specifications against the official datasheet before integration. Ensure the physical dimensions match your panel cutout requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when high-current filtering is required alongside significant capacitance values. The axial lead configuration facilitates easy installation into chassis panels. Consider the operating temperature range to ensure reliability under thermal stress. Compare the physical size constraints against available space in the target enclosure.
