Military Quartz
Crystals
Military quartz crystals are designed, manufactured and
qualified to military specification MIL-PRF-3098/H. Qualified
manufacturers are identified and listed on the US Government's
Qualified Products List and are said to a QPL supplier for the
items. Due to the extensive number of crystal types and designs, the
Government has developed and published general specifications for
designs of similar frequency, mode and overall performance. The
individual specifications are called "slash-sheets" and are
referenced back to the general military specification
MIL-PRF-3098/H.
