MC-306 32.7680K-A0:PURE SN Description

Short technical summary and product information.

The Epson MC-306 32.7680K-A0:PURE SN is a kHz tuning fork crystal designed for precision timing applications. It operates at a fundamental frequency of 32.768 kHz with a frequency tolerance of ±100ppm and a load capacitance of 12.5pF. The equivalent series resistance is 50 kΩ, ensuring reliable oscillation in low-power circuits.

This crystal is housed in a compact 4-SOJ surface-mount package measuring 8.00mm x 3.20mm with a height of 2.54mm and a lead spacing of 5.50mm. It supports an operating temperature range of -40°C to +85°C, making it suitable for industrial and consumer environments.

Typical applications include real-time clocks (RTCs), timing modules, and low-frequency oscillator circuits where stable and accurate frequency reference is required. The tuning fork design provides low power consumption and excellent long-term stability.
