M in mm 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. glue crystal PC board heat isolating material Order Information Q frequency type load capacitance Quartz 0.032768 MHz MTF32 6 pF ~ 12.5 pF 10.0 pF Std. 12.5 pF Std.
