ABS05W-32.768KHZ-J-2 is a 32.768 kHz IoT-optimized SMD tuning fork crystal designed for wearables, wireless modules, and low-power applications. It features an exceptionally low load capacitance of 4.0 pF and is optimized for low ESR over an extended operating temperature range of -40°C to +105°C. The crystal offers a frequency tolerance of ±20 ppm at +25°C and is housed in a miniature 1.6 x 1.0 x 0.5 mm seam-sealed package for long-term reliability. With typical ESR values below 60 kO over the operating temperature range and a Q value of 8,000 minimum, this crystal is ideal for Bluetooth/BLE, NFC, M2M connectivity, and ultra-low power MCU applications.
