Nihon Dempa Kogyo Co. Ltd (NDK) has announced the availability of what it claims is the world's smallest high reliability surface mount crystal.

The NX1612AA series measures 1.6mm x 1.2mm x 0.3mm, taking 40 percent of the volume and 60 percent of the board space of NDK's previous generation crystal products. The devices operate in a fundamental frequency range of 26MHz to 80MHz.

Frequency tolerance at 25C is 10ppm and their frequency stability vs. temperature is: 10ppm over -20 to +70C. The NX1612AA exhibits a maximum series ESR (equivalent series resistance) of 200W in the frequency range of 26MHz to 36 MHz and 100W in the 36MHz to 80 MHz frequency range. The Standard load capacitance is 7pF. However, other values can be made available.

Applications for this tiny crystal include mobile phones, Bluetooth, WLAN, Zigbee, NFC, and many other small wireless devices and module components. The NX1612AA is presented in a Pb-free, RoHS conformance package and meet the re-flow profiling requirements for Pb-free solder.

Its price is less than $1 in 10k quantities.
