MC-306 32.7680K-A0 Description

Short technical summary and product information.

The Epson MC-306 32.7680K-A0 is a 32.768 kHz tuning fork crystal designed for surface mount applications. It operates in fundamental mode with a load capacitance of 12.5 pF and an equivalent series resistance of 50 kΩ maximum. The frequency tolerance is ±100 ppm at +25°C, and the operating temperature range is -40°C to +85°C. This crystal is housed in a 4-SOJ package with a 5.50 mm pitch, measuring 8.00 mm x 3.20 mm x 2.54 mm. Typical applications include real-time clocks (RTCs), timing circuits, and low-frequency oscillators. The drive level is 1.0 µW maximum, and the shunt capacitance is 0.9 pF typical. The crystal is RoHS3 compliant and has an MSL of 1 (unlimited).
