Description
The YT38 32.768 kHz Crystal is a high-precision quartz resonator optimized for low-power, real-time clock (RTC) applications. Its fundamental frequency of 32.768 kHz is the global industry standard for timekeeping, as it is exactly $2^{15}$ cycles per second, allowing digital circuits to easily derive a precise 1-second pulse through simple binary division.
Housed in a compact 8mm x 2.8mm cylindrical radial package, this crystal is designed for space-efficient through-hole mounting. It is ideal for integration into battery-operated devices such as portable electronics, data loggers, and RTC modules where power consumption must be kept to an absolute minimum while maintaining long-term timing accuracy.
