J21SMX Series SMD Quartz Crystals

The J21SMX series of SMD quartz crystals from Jauch Quartz are designed to meet the demands of multiple industrial and consumer applications. With a compact 2016 seam-sealed package and 4-pad configuration, these AT-cut MHz crystals offer excellent frequency stability and reliability in space-constrained designs. The J21SMX series supports a frequency range of 16.0 MHz to 48.0 MHz, with a tight frequency tolerance of ±10 ppm/±30 ppm at +25°C, making them suitable for all types of applications requiring a timing reference. These crystals are engineered for high performance across a wide operating temperature range of -40°C to +85°C, with low shunt capacitance (< 3 pF) and a recommended drive level of 10 µW (maximum 100 µW), ensuring energy-efficient operation. First-year aging is limited to ±3 ppm, supporting long-term frequency accuracy. Fully compliant with RoHS and REACH regulations, the J21SMX series is 100% lead-free and conflict minerals-free, supporting sustainable and responsible manufacturing practices.
