Q-Tech Corp. announces the availability of the QTCH Series of ultra-miniature crystal oscillators for high-temperature, applications. With a wide operating temperature range of -55C to 200C and offered in small, low-profile, surface-mount package sizes, the QTCH series is ideal for down-hole drilling as well as a host of other high-temperature, high shock/vibration applications.

The QTCH series are miniature surface-mount (SMD) crystal oscillators supporting frequencies between 1 and 48 MHz. The devices are capable of operating over a wide supply voltage range from 1.8 to 5 Vdc and exhibit very low power consumption (< 3 mA).  QTCH Series components are offered in three low-profile ceramic packages (2.5 mm x 3.2 mm, 3.2 mm x 5 mm and 5 mm x 7 mm) are hermetically sealed with gold plated contacts or hot solder dipped.

 “The QTCH Series answers the demand for superior performance in extreme high-temperature applications,” said Scott Sentz, Q-Tech’s director of sales and marketing. “Just as with our low-earth-orbit and other military/aerospace crystals, the QTCH Series goes to places where failure isn’t an option.”

OTCH Series oscillators are ECCN: EAR99 classified, lead-free and RoHS compliant. Military screening per MIL-PRF-55310 is also available.
