20kHz to 100MHz frequency range
5X7 SMD form factor
Hermetically sealed for rugged environmental
conditions
Extremely wide operating temperature range
accommodates harsh environments
Crystals are processed with tight angle control to
assure best frequency-temperature characteristics
Units are vacuum baked before sealing at 175°C for
16 hours to eliminate moisture traces and pre-age
units for superior stability
Tristate feature optional
Equivalent 5V parts are available in T1250 series
Solder coating of outer pads upon request
Applications

Applications that require an HCMOS 3.3V clock
and might be exposed to extremely harsh
environmental conditions.
Tinned pad parts are
5/6 RoHs compliant
Description
Owing to their small size, light weight, and
rugged characteristics, these 3.3V HCMOS
extended temperature/COTS oscillators fulfill
tasks not previously feasible. They are used in
applications that take advantage of their
extended temperature range and high
performance. Twenty four different models (with
and without tristate) cover -55°C to +200°C
operation and provide frequency selection from
20kHz to 100MHz. They combine excellent longterm reliability, loading characteristics, and
superior startup performance.
