Description
The 32.768 kHz quartz crystal is the industry-standard timing reference used to drive real-time clock (RTC) circuits in almost all digital devices. This specific version comes in a compact DIP (Dual In-line Package), measuring 8mm x 3mm, making it ideal for breadboarding, prototype development, and through-hole PCB assembly.
Because the frequency is exactly 32,768 Hz, it can be divided by a simple 15-stage binary counter ($2^{15} = 32,768$) to generate an exact 1 Hz (one pulse per second) signal. This makes it the foundation for accurate timekeeping in everything from wristwatches to industrial data loggers. With a tight frequency tolerance of ±20 ppm and a load capacitance of 12.5 pF, these crystals ensure high precision and low power consumption, perfect for battery-operated systems.
