ABS05W-32.768KHZ-K-2 is a 32.768 kHz IoT-optimized SMD tuning fork crystal designed for wearables, wireless modules, and IoT applications. It features an exceptionally low load capacitance of 4.0 pF, a frequency tolerance of ±20 ppm at +25°C, and an extended operating temperature range of -40°C to +125°C. The crystal offers optimized ESR performance with typical values below 65 kO over the full temperature range and a maximum of 85 kO. Housed in a miniature 1.6 x 1.0 x 0.5 mm seam-sealed package, it is ideally suited for space-constrained designs requiring long-term reliability. Common applications include Bluetooth/BLE, ultra-low power MCUs, NFC, and machine-to-machine connectivity.
