9 / 35 page Piezoelectric Diaphragms Notice c Notice (Soldering and Mounting) 1. Applying load on the center area of the diaphragm may cause cracking in the ceramic element. When the diaphragm is supported by the edge, the load should be applied only around the edge. 2. Please consult with a Murata representative if soldering of the component is needed. 1. Please do not touch the component with a bare hand because the electrode may become corroded. 2. The component may be damaged if mechanical stress exceeding specifications is applied. 3. Take care to protect the operating circuit from surge voltage resulting from excessive force, falling, shock or temperature change. 4. If DC voltage is applied to the component, silver migration may occur. Please strictly avoid subjecting the component to DC voltage for long periods. 5. The resistor should be used as shown in Fig. A. A suitable resistance value should be chosen, preferably 1k Ω to 2kΩ. Instead of this measure, a diode may also be applied as shown in Fig. B. 6. Avoid excessive pulling of the lead wire because the wire may break or the soldering point come off.
