Self-drive Piezoelectric Ceramic Element (Diameter 27mm by Thickness 0.2mm, 3.9kHz) 1, No minimum order requirement; 2, Make formula by ourselves; 3, Each procedure is under control. Main feature of Piezo Ceramic Element: -Extremely thin and light; -Low power consumption; -No EMI\RFI. Piezo Ceramic Element:Applications (Piezoceramics element; Piezodiaphragm, piezo plate) 1, For sound making:Clocks,Calculators,Telephones,Washing machines,Various(Burglar alarms,etc); 2, For transduction: Embryo monitor,Heart reflectoscope reflector,pedometer, car alarm sensor. Brief description of piezoceramic element&Attributive Characters: 1, Electrode form/ Modulating: External drive (diode); Self drive (transistor); 2, Thickness: Thick(T>0.5mm); Standard(0.5mm>T>0.2mm); Thin (T<0.2mm); Thinnest (0.03 0.05um); 3, Dimension: Smallestdiameter is8mm, Biggest is 65mm; 4,Metal plate types: Brass, Nickel, Stainless steel; 5,Connection terminal: Solder wire or not. Handing Notice: 1, Please do not touch the component with bare hand because electrode may be corroded. 2, The component may be damaged if mechanical stress exceeding specifications is applied. 3, Take care to protect operating circuit surge voltage resulting excessive force,falling,shock temperature change. 4, If DC voltage is applied to the component ,silver migration may occur .Please pay full attention to avoid subjecting. 5, Avoid excessive pulling lead wire because wire may break or soldering point may come off . 6, Applying Load on the center of the diaphragm may cause cracking in the ceramic elements .When the diaphragm is supported by the edge ,the load should be only applied around the edge. Soldering procedures: When using a soldering iron ,the optimum temperature for soldering a lead wire to a metal plate is 340°c±10°c for 1-2 second and the same temperature for the ceramic Silver electrode for 0.5 second or less. SWT piezo diaphragm’s excellences: 1, All the piezo diaphragm have our own intellectual property, own brand “SWT”. From the beginning of formula creation of the products to finished goods, all production procedure is proceeded and monitored in our factory. 2, Features of our products is with extremely clear sound, stable performance , good looking, high indemnification special in resistance of break, drop, ultrasonic weld attack. 3,We are a Hong Kong owned company and have the legal right to declaration transfers the factory and issue the 17% increment duty receip, Products can be exported from Hong Kong to world wide.
