Circuit designers pressed for space should
check out Micro Crystal’s MHz quartz crystal, the CC7A-T1A at the MDM
Minneapolis Conference Booth 852. Designed for application in implantable medical
and medical telemetry and other high-reliability markets, this precision timing
crystal has a package height of 0.90mm and a footprint of only 3.2 x 1.5mm.
This is the smallest size available for implantable crystals and marks an extension
of the new small size line-up of implantable, high-reliable crystals of Micro
Crystal. An already-released, low frequency version, covers from 30 to 500kHz
and 32,768Hz and comes in the same package.The AT cut quartz crystal CC7A-T1A offers a wide temperature range, up to -40 to +85/+125°C, and a high-thermal stability for medical applications (down to +/-10ppm), which meet the requirements for wireless applications. Low aging and very high 5.000g shock and vibration resistance combine to make this device ideal to meet the specifications of the high-reliable market applications. An innovative crystal design provides performance comparable to larger devices. The CC7A-T1A is RoHS compliant and 100% lead free.
Micro Crystal also offers extended custom
testing conditions in order to meet the requirement of cardiologic and
neurostimulation applications for implantable devices, including particle
detection,
X-ray scanning and others. Standard frequencies are 24.0, 26.0 and 26.5MHz,
with other frequencies in the 24 to 30MHz range upon request. All frequencies
are generated in fundamental mode. The crystals are supplied in special trays
(170 crystals per tray). For pick-and-place equipment, the parts are available in
12 mm tapes: 7” (178 mm) reel with 3’000 crystals13” (330 mm) reel with 14’000
crystals.
Medical applications include: implantable devices, pacemaker, cardiologic and neurostimulation devices and other high-reliability markets.
