Designed for applications in implantable medical and medical telemetry, avionics, automotive and other high-reliability markets, this precision timing crystal has a package height of 0.90mm and a footprint of only 3.2mm 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 30Hz to 500kHz and 32.768kHz and comes in the same package.
Intended for critical timing applications, the AT cut quartz crystal CC7A-T1A offers a wide temperature range, up to -40 to +85°C/+125°C, and a high thermal stability for medical applications (down to +/-10ppm), which meets 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 screening 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 24MHz, 26MHz and 26.5MHz, with other frequencies in the 24MHz 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 12mm tapes: 7in (178mm) reel with 3,000 crystals 13in (330 mm) reel with 14,000 crystals.
Applications include: Implantable devices, pacemaker, cardiologic and neurostimulations in high reliable markets.
The Micro Crystal CC7A-T1A is available in production quantities, with eight to sixteen weeks lead time. Prices are dependent on custom testing specifications and range from $4 to $20 each in 10,000 piece lots. A datasheet is available here.
