ABM12W-48.0000MHZ-8-D2X-T3 is an IoT-optimized low-profile quartz crystal designed for energy-saving wearables and wireless applications. Operating at a fundamental frequency of 48.0000 MHz with an 8 pF load capacitance, this crystal features an exceptionally compact form factor of 1.6 × 1.2 × 0.4 mm, making it ideal for height-constrained designs. The device operates over a temperature range of -40°C to +125°C with frequency tolerance of ±10 ppm at +25°C and frequency stability of ±10 ppm over the operating temperature range. With an equivalent series resistance (ESR) maximum of 50 O at the 37.0000–52.0000 MHz range and a shunt capacitance (C0) of 2.0 pF maximum, this crystal delivers optimized performance with low power consumption (10–100 µW drive level). The seam-sealed construction ensures long-term reliability, making it well-suited for Bluetooth/BLE modules, wireless IoT devices, machine-to-machine connectivity, and ultra-low-power microcontroller applications.
