HC49US-49.152MABJ-UB is a quartz oscillator made by Citizen for their watch products. It is a high-stability crystal that provides precise and reliable timing for quartz movement watches. It has an insulated metal case (IMC) with a gold-plated finish that prevents corrosion, a frequency of 32.768 kHz, and load capacitors of 8pF and 22pF. The assembly has a 49.152mm diameter, justifying the first three numbers of its part number. The oscillator is designed for temperatures between -30 to +85 degrees Celsius and an operational current of 0.3mA. It has an impressive maximum pull range of ±300ppm, allowing it to accurately track the time even under difficult conditions. It is widely used in the Citizen watch family, as well as many other leading watchmakers.
