Model:AB26T- 32 . 768KHZ
Manufacturer：Abracon LLC
Stocks：2000
Describe：

32.768kHz fork-type quartz crystal resonator, with a cylindrical radial through-hole package. The frequency is the standard 32.768kHz, the load capacitance is 12.5pF, the frequency tolerance is ±20ppm, and the equivalent series resistance (ESR) is 35kΩ. This frequency is the standard time reference frequency for real-time clock (RTC) circuits, and after 15 stages of binary division, it can precisely generate a 1-second signal. It is suitable for various electronic devices that require precise timing and low power consumption operation.
