18 / 35 page Piezoelectric Sounders (External Drive Pin Type Taping) Circuit/Notice 510 Ω 20kΩ 20k Ω 510Ω 1k Ω +V 1k Ω 0.01μF 0.01μF +V 1k Ω 1k Ω 120k Ω 1M Ω Input 0.001μF The following are examples of externally driven circuits. (1) Unstable multi-vibrator using Tr. (2) Circuits using inverters or NAND gates. (1) (2) c Circuit c Notice (Soldering and Mounting) 1. The component may be damaged if mechanical stress exceeding specifications is applied. 2. Take care to protect the operating circuit from surge voltage resulting from excessive force, falling, shock or temperature change. 3. If DC voltage is applied to the component, silver migration may occur. Please strictly avoid subjecting the component to DC voltage for long periods. 4. 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. 5. Avoid excessive pulling of the lead wire because the wire may break or the soldering point come off. IC Fig. A IC Fig. B R c Notice (Handling) P37E.pdf Feb.1,2012 16 !Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc. • This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please review our product specifications or consult the approval sheet for product specifications before ordering. 3 1. Notice (Soldering and Mounting) (1) Soldering Iron (a) Immerse lead terminals up to 1.5mm from component's body in soldering bath of +260±5°C for 10±1.0 seconds, and then leave components in natural conditions for 4 hours. (b) Directly contact the lead terminal with the tip of the soldering iron for +350±5 °C for 3.0±0.5 seconds, and then leave components in natural conditions for 4 hours. (2) Reflow The component cannot withstand reflow soldering. 2. Please do not insert the component on double-sided PCB with plated through hole. When melted solder touches the base of lead terminal, a part of the plastic case may melt, causing electrical failure. 3. Washing of the component is not acceptable. Because it is not sealed. |
