Rem em ber to protect these leads from m oisture and contam ination as leakage paths can inhibit proper oscillator function. www.pletronics.com 425-776-1880 3 SM8S Series Low Frequency Crystal October 2013 Reflow Cycle (typical for lead free processing) The part m ay be reflowed 2 tim es without degradation.
