NOTES:
1 Consult factory for parts ordering information
2 Screening based on MIL-PRF-19500. Screening flows available on request. X-Ray shall be performed in lieu of Precap Inspection – Consult Factory.
3 Consult factory for package outline
4 Pulsed @ 300μs nominal, other pulse widths will provide different results due to self heating
