B U Z Z E R S January 2019 Piezoelectronic buzzers Pin terminal/Lead lines/SMD(Without oscillator circuit) PS series Pin terminal type PS12 PS14 PS17 PS19 Lead wire type PS15 SMD type PST14

(2/17) B U Z Z E R S Piezoelectronic buzzers Product compatible with RoHS directive Pin terminal/Lead lines/SMD(Without oscillator circuit) Overview of the PS series FEATURES Sounding body(unimorph) that piezo bonded the diaphragm is used, and attach on circuit, and is easy design high performance effi- ciency piezoelectric buzzer. They feature extremely low power consumption in comparison to electromagnetic units. Because these buzzers are designed for external excitation, the same part can serve as both a musical tone oscillator and a buzzer. They can be used with automated inserters. Moisture-resistant models are also available. The lead wire type(PS1550L40N) with both-sided adhesive tape installed easily is prepared. APPLICATION Electric ranges, washing machines, computer terminals, various devices that require speech synthesis output. RECOMMENDED OPERATING CIRCUIT EXAMPLE VCC ∗R Pbuiezzzoeerlectric C-MOS, etc R Tr (Equivalent to C1815) GND ∗Resistor to do charging and discharging to a piezoelectric element (Value of about 1kΩ is good efficiency). SOUND MEASURING METHOD Piezoelectric Standard buzzer microphone AMP Filter (A curve) DC power Driver supply circuit Measuring Testing input voltage distance Recorder 10cm Anechoic chamber Frequency counter RoHS Directive Compliant Product: See the following for more details. https://product.tdk.com/info/en/environment/rohs/index.html Please be sure to request delivery specifications that provide further details on the features and specifications of the products for proper and safe use.

(17/17) B U Z Z E R S REMINDERS FOR USING THESE PRODUCTS Before using these products, be sure to request the delivery specifications. SAFETY REMINDERS Please pay sufficient attention to the warnings for safe designing when using this products. REMINDERS Please be sure to read the specifications of TDK electromagnetic buzzer(hereinafter referred to as “the buzzer”) before use. Do not apply DC bias to the piezoelectric buzzer; otherwise insulation resistance may become low and affect the performance. Do not supply any voltage higher than applicable to the piezoelectric buzzer. Do not use the piezoelectric buzzer outdoors. It is designed for indoor use. If the piezoelectric buzzer has to be used outdoors, provide it with waterproofing measures; it will not operate normally if subjected to moisture. Do not wash the piezoelectric buzzer with solvent or allow gas to enter it while washing; any solvent that enters it may stay inside a long time and damage it. A piezoelectric ceramic material of approximately 100m thick is used in the sound generator of the buzzer. Do not press the sound generator through the sound release hole otherwise the ceramic material may break. Do not stack the piezoelectric buzzers without packing. Do not apply any mechanical force to the piezoelectric buzzer; otherwise the case may deform and result in improper operation. Do not place any shielding material or the like just in front of the sound release hole of the buzzer; otherwise the sound pressure may vary and result in unstable buzzer operation. Make sure that the buzzer is not affected by a standing wave or the like. Be sure to solder the buzzer terminal at 350°C max.(80W max.)(soldering iron trip) within 5 seconds using a solder containing silver. Avoid using the piezoelectric buzzer for a long time where any corrosive gas H2S, etc.) exists; otherwise the parts or sound generator may corroded and result in improper operation. Be careful not to drop the piezoelectric buzzer.
