Abracon ABS05/ABS05W 32.768kHz IoT Optimized SMD Crystals

Abracon ABS05/ABS05W 32.768kHz Internet of Things (IoT) Optimized SMD Crystals feature an exceptionally low 4pF or 12.5pF plating load with simultaneous ESR optimization over an extended operating temperature range. The seam-sealed ABS05W components provide long-term reliability with a 20ppm tolerance and 0.5µW maximum drive level. ABS05 and ABS05W crystals are offered with operating temperature ranges from -40° up to +85°, +105°, or +125°C. These Abracon IoT crystals are ideal for wearables, wireless modules, BLUETOOTH®, machine-to-machine connectivity, NFC, and ultra-low power applications.
