QTCH High Temperature Oscillators
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.
Highlights
- Packages as small as 2.5 x 3.2 mm.
- Gold plated standard lead finish.
- Sn60/Pb40 hot solder dip or SAC305 lead free solder are available for an additional cost.
- High temperature range of -55ºC to +200ºC.
- Qualified to MIL-PRF-55310, Level B.
- High Reliability.
- Quick lead times, 8 weeks guaranteed worst case, 2 weeks typical for repeat orders.
- Shock data available upon request.
- Stocking many standard frequencies. Please contact the factory for list.
