Features
• QML Class T, Per MIL-PRF-38535
Intersil‘s Satellite Applications FlowTM (SAF) devices are
fully tested and guaranteed to 100kRAD total dose. These
QML Class T devices are processed to a standard flow
intended to meet the cost and shorter lead-time needs of
large volume satellite manufacturers, while maintaining a
high level of reliability.
