HIGH TEMPERATURE CRYSTALS
Leaded/High Temperature/High Frequency
DESCRIPTION
An increasing number of applications require the use of
high-temperature crystals. For these applications, Statek
offers the CX1HT-06, CX2HT-06 and CX2HT-07 leaded
crystals. These crystals are designed to operate at
temperatures up to and including 175ºC. The frequency
range offered is 6 MHz to 250 MHz for CX1HT-06 and
9.6 MHz to 250 MHz for CX2HT-06 and CX2HT-07
crystals. The expected life at 175ºC is in excess of 1,000
hours.
