Jauch Quartz's JXS-WA series quartz crystals for wireless applications are available in standard packages of 2016, 2520, and 3225, and at 14 standard frequencies which are required to generate a pure and stable reference clock for many RF-transceivers and RF-ASICs. Typical frequencies such as 24.0 MHz, 26.0 MHz, 32.0 MHz, 37.40 MHz, 38.40 MHz, or 40.0 MHz are often used by RF-ASICs that support wireless standards like Bluetooth® Low Energy (BLE), Bluetooth Smart, Zigbee®, ISM, LoRa, LPWAN, or any of the other standards being used in wireless applications within the world of Internet of Things (IoT). Due to their high-frequency stability as well as their very low equivalent series resistance (ESR), these special crystals meet the high requirements that are essential for IoT and other wireless applications.<strong>Features:</strong> Frequencies for IoT and wireless applications:16.0 MHz, 19.20 MHz, 20.0 MHz, 24.0 MHz, 25.0 MHz, 26.0 MHz, 27.120 MHz, 30.0 MHz,  32.0 MHz, 37.40 MHz, 38.40 MHz, 40.0 MHz, 48.0 MHz, and 52.0 MHz, Lowest aging: ±1 ppm 1st year and very low long-term aging, Tight frequency tolerance: ± 10 ppm at +25°C, High-frequency stability in temperature ranges:, ±10 ppm in -20°C to +70°C, ±15 ppm in -40°C to +85°C, ±30 ppm in -40°C to +105°C, Small ceramic/metal packages, 2016 (2.0 mm x 1.6 mm x 0.45 mm), 2520 (2.5 mm x 2.0 mm x 0.55 mm), 3225 (3.2 mm x 2.5 mm x 0.65 mm), EMI shielding possible by a grounded lid, Low ESR guarantees excellent compatibility with RF-ASICs, Wireless applications, IoT and Industrial IoT (IIoT), Bluetooth / BLE / Bluetooth Smart, Zigbee, ISM, Wi-Fi / WLAN, LPWAN, and more, Telecommunications, Wearables
