ABM12W-27.1200MHZ-7-D1X-T3 is an IoT-optimized low-profile quartz crystal designed for energy-saving wearables and wireless applications. The device operates at a fundamental frequency of 27.12 MHz with a load capacitance of 7 pF and frequency stability of ±15 ppm over the operating temperature range of -40°C to +85°C. It features an exceptionally low profile of 0.4 mm maximum height with compact dimensions of 1.6 × 1.2 mm, making it ideal for height-constrained designs, and is seam-sealed for long-term reliability with low plating capacitance and optimized equivalent series resistance. This crystal is well-suited for Bluetooth/BLE modules, wireless connectivity, ultra-low power microcontrollers, NFC applications, and ISM band devices where compact form factor and low power consumption are critical requirements.
