ABM12W-27.0000MHZ-6-D1X-T3 is a 27.0000 MHz fundamental mode quartz crystal designed for energy-saving wearables and IoT applications. This ultra-low profile crystal features a compact 1.6 x 1.2 x 0.4 mm ceramic package with a 6 pF load capacitance and operates over a temperature range of -40°C to +85°C. It offers a frequency tolerance of ±10 ppm at 25°C and frequency stability of ±20 ppm over the operating temperature range, with an equivalent series resistance (ESR) of 100 O maximum for the 24.0000-31.9999 MHz frequency range. The seam-sealed construction ensures long-term reliability, making it ideal for Bluetooth/BLE, wireless modules, M2M connectivity, and ultra-low power MCU applications.
