- Critical infrastructure power supplies
Procurement Notes
Verify the specific suffix URS against official datasheets to confirm surface-mount packaging and hermetic sealing requirements. Ensure procurement channels provide traceability documentation compliant with military specifications. Confirm RoHS status as non-compliant due to military grade classification. Validate lot traceability records are available for quality assurance purposes.
Selection Notes
Select this component when hermetic sealing and ultrafast recovery are mandatory for system reliability. Compare against through-hole variants if board space permits alternative mounting styles. Consider thermal management requirements associated with the D-5A-2 surface mount footprint during circuit design integration.
