Q-Tech now offers ultra-miniature high temperature oscillators in packages as
small as 2.5 x 3.2 mm. These oscillators are fully qualified, configuration con-
trolled, and thoroughly tested to meet the same high standards as our older, bigger
products, while still being capable of covering temperature ranges of -55 ºC to
+200 ºC. Furthermore, Q-Tech offers short lead times, with 8 weeks maximum
and in many cases only 2 weeks lead time for standard parts.
