T: 3rd OT example 4.0 MHz / 12 pF: 4a000 Mounting Mounting: if the crystal should be mounted vertically to your board (see picture), do not directly solder the metal can. The crystal may be overheated by the direct heat flow. Please use glue (hot-melt adhesive) or mechanical clamping to fasten the metal can. crystal glue PC board heat isolating material Order Information Q frequency type Quartz 3.50 ~ 48.0 MHz MTF38 load capacitance in pF 30 pF standard 12 pF ~ 32 pF S for series stability at 25 °C 30 = ± 30 ppm std option stability vs. temp. range see table blank = T1= FU = 3OT = -20 °C ~ +70 °C -40 °C ~ +85 °C for fundamental frequencies ≥ 20 MHz 3rd overtone Example: Q 30.0-MTF38-30-30/30-FU Jauch Quartz GmbH • e-mail: [email protected] full data can be found under: www.jauch.de / www.jauch.co.uk / www.jauch.fr / www.jauchusa.com All specifications are subject to change without notice 200911-18
