NDK announces the availability of a series of ultra small, thin, surface mount crystals. The NX2016AA series measures L=2.0mm × W=1.6mm × H=0.45mm, measuring half the volume of any of NDK’s other crystal products. These crystals operate in a fundamental frequency range of 24 to 80 MHz while weighing just 6 mg. Their frequency tolerance is ± 15 ppm to 100 ppm over the operating temperature range of 㪢 to +75°C. The NX2016AA maximum series ESR (equivalent series resistance) in the frequency range of 24 to 25 MHz is 100Ω, 25 to 36 MHZ is 80Ω, and 30 to 80 MHz is 60Ω. The drive level is 50µW and has a standard load capacitance of 8pF. Applications include mobile phones, Bluetooth, WLAN, Zigbee and NFC. The NX2016AA is presented in a lead-free, RoHS conformance package. They meet the requirements for re-flow profiling using lead-free solder.
