- What it is
A two‑pin piezoelectric element cut from quartz. - Function
By itself it doesn’t oscillate—you must hook it up to an external inverter or amplifier plus two load capacitors to form an oscillator circuit. - Key specs
- Frequency tolerance: typically ±10–30 ppm (±0.001–0.003 %)
- Stability: excellent over temperature (often < 50 ppb/°C)
- Aging: < 5 ppm/year
