ABS05W-32.768KHZ-D-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, a frequency tolerance of ±20 ppm at +25°C, and an operating temperature range of -40°C to +85°C. The crystal operates in flexural (tuning fork) mode with an ESR of less than 50 kO typical at +25°C and a Q value of 8,000 minimum. Housed in a miniature 1.6 x 1.0 x 0.5 mm seam-sealed SMD package, it is RoHS/RoHS II compliant and ideal for space-constrained designs. Common applications include Bluetooth/BLE, NFC, M2M connectivity, and ultra-low power MCUs where long-term reliability and energy efficiency are essential.
