Le facteur Q mesure la perte d’énergie à l’intérieur du quartz. Il est assuré par la qualité du quartz brut, la finition de la surface, le montage et le scellement. Plus le Q facteur est élevé et plus le quartz est de bonne qualité. Plus la fréquence est élevée et plus le facteur Q devient un élément important pour l’ingénieur design. La stabilité maximale court-terme du quartz  dépend également du facteur Q. La gamme de fréquence va de 10 à 42MHz en mode fondamental, de 10 à 125MHz au 3ème harmonique et de 70 à 175 MHz au 5ème harmonique.
\nCette nouvelle gamme offre un vieillisssement lent à 0.1ppm par an et une tolérance à 25 °C jusqu’à ±3ppm. A titre de comparaison, un quartz standard a un vieillissemnt de 3ppm par an et une tolérance de  ±10ppm. La stabilité en température de 4ppm de 0 à 70 °C et de 12ppm de -40 à 85 °C peut être spécifiée en fonction de l’application du client.
\nLe bruit de phase est critique dans beaucoup d’applications et notre nouvelle gamme est très performante dans ce domaine, y compris sur les hautes fréquences jusqu’à 100MHz au 5ème harmonique.<\/p>\n
