12 MHz SMD Crystal Oscillator – YSX321SL YXC High-Stability Quartz Crystal

Datasheet

Product Description:

The YSX321SL 12 MHz SMD Crystal Oscillator (YXC) is a compact, high-stability quartz crystal designed for precise clock generation in microcontrollers, processors, communication modules, and consumer electronics. With its 3.2 × 2.5 mm (3225) SMD package, this crystal offers excellent frequency accuracy, low ESR, and reliable long-term performance.

This 12 MHz crystal uses an AT-Fundamental vibration mode and features low shunt capacitance and strong temperature stability (±10 ppm), ensuring consistent oscillation in sensitive digital and RF circuits. Ideal for embedded systems requiring stable clock timing, such as USB interfaces, MCUs, and communication devices.
