The crystal may be overheated by the direct heat flow. Please use glue (hot-melt adhesive) or mechanical clamping to fasten the metal can. glue crystal PC board heat isolating material Order Information Q Quartz frequency type load capacitance in pF 30 pF standard 12 pF ~ 32 pF S for series stability at 25 °C 30 = ± 30 ppm std stability vs. temp. range see table blank = T1= FU = 3OT = option 3.579545 ~ 91.0 MHz MTF38 -20 °C ~ +70 °C -40 °C ~ +85 °C for fundamental frequencies ≥ 20 MHz 3rd overtone Example: Q 30.0-MTF38-30-30/30-FU J auch Quartz GmbH • e-mail: info@jauch.de full data can be found under: www.jauch.de / www.jauch.fr / www.jauchusa.com All specifications are subject to change without notice
