QTCH HIGH TEMPERATURE MINIATURE SMD OSCILLATORS
Description
Q-TECH
CORPORATION
5 x 7mm, 3.2 x 5mm, 2.5 x 3.2mm, SMD UP TO 200ºC
2.5Vdc and 3.3Vdc - 32.768 kHz*
The QTCH series are miniature surface-mount (SMD) crystal
oscillators supporting 32.768kHz* fundamental mode operating
in a wide supply voltage range from 2.5Vdc to 3.3Vdc, very low
power consumption (<3mA) with a temperature range from -
55ºC to +200ºC. Package offerings in three low profile ceramic
packages, 2.5x3.2mm, 3.2x5.0mm and 5.0x7.0mm, which are
hermetically sealed with gold plated contacts or hot solder
dipped.
