LOW ESR QUARTZES FOR RAPID OSCILLATION START-UP
Very cost-effective quartz resonators provide the basis of our extremely broad and deep product range “SMD 晶振” for the vertical market “IoT and LPWAN”. These extremely durable SMD crystals in various miniaturized ceramic housings in AT-Fundamental frequency range of 12 – 64 MHz have very low resistances, so that they oscillate optimally and particularly fast in the customer circuit. The standard frequency tolerance is ± 10 ppm at + 25° C. The temperature stabilities are in the standard ± 10ppm @ -20 / + 70° C or ± 15ppm @ -40 / + 85° C. After 10 years, the aging is ± 10ppm max. so that they can be used in any radio application due to the parameterization of the miniaturised SMD crystals. The list of design references on our website is currently being adapted and provides information which quartz crystal is suitable for which IC. If higher frequency accuracies are needed, we recommend our Low Cost TCXOs for use in narrow band applications.
Obviously, we can not only supply very low-cost components, but also have an exceptionally broad range of design-in services through our in-house engineering and offer even the measuring of suitable SMD crystals directly in the customer circuit.
We recommend to use for new developments the cheapest 3.2 × 2.5 mm ceramic housing (series SMD03025/4). However, if this housing is too large, then we recommend using the 2.0 × 1.6 mm (SMD02016/4 Series) ceramic package. Due to the steadily increasing demand for the 2.0 × 1.6 mm ceramic housing, quartz crystals in this housing are already cheaper than SMD crystals in 2.5 × 2.0 mm ceramic housing.
In addition to the reference MHz crystals, our product range offers various 32.768 kHz quartz crystals and Ultra Low Power oscillators.

低ESR石英振荡器迅速启动物联网和LPWAN
非常具有成本效益的石英谐振器为垂直市场“IoT和LPWAN”提供了极其广泛和深入的产品范围“SMD晶体”的基础。在12 - 64 MHz的at基频范围内，这些非常耐用的SMD晶体在各种小型化陶瓷外壳中具有非常低的电阻，因此它们在客户电路中振荡最佳且特别快。标准频率公差为±10ppm， + 25℃。温度稳定性在标准±10ppm @ -20 / + 70℃或±15ppm @ -40 / + 85℃。 10年后，老化最大±10ppm。，因此，由于小型化SMD晶体的参数化，它们可以用于任何无线电应用。我们网站上的设计参考清单目前正在调整，并提供了哪些石英晶体适合哪些集成电路。如果需要更高的频率精度，我们推荐我们的低成本TCXOs用于窄带应用。
显然，我们不仅可以提供非常低成本的组件，而且还可以通过我们的内部工程提供非常广泛的设计服务，甚至可以直接在客户电路中测量合适的SMD晶体。
我们建议使用最便宜的3.2 × 2.5 mm陶瓷外壳(系列SMD03025/4)进行新开发。但是，如果这个外壳太大，那么我们建议使用2.0 × 1.6 mm (SMD02016/4系列)陶瓷封装。由于对2.0 × 1.6 mm陶瓷外壳的需求稳步增长，这种外壳中的石英晶体已经比2.5 × 2.0 mm陶瓷外壳中的SMD晶体便宜。
除了参考MHz晶体外，我们的产品系列还提供各种32.768 kHz和超低功率振荡器。
