Piezoelectronic Buzzers Pin terminal/Lead Without oscillator circuit PS series Issue date: May 2011 • All specifications are subject to change without notice. • Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications. (1/7) Piezoelectronic Buzzers(without circuit) PS Series(Pin Terminal/Lead) Conformity to RoHS Directive FEATURES APPLICATIONS • The PS series are high-performance buzzers that employ unimorph piezoelectric elements and are designed for easy incorporation into various circuits. • 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. Electric ranges, washing machines, computer terminals, various devices that require speech synthesis output.

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 100µm 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 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). 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. • All specifications are subject to change without notice. 007-01 / 20110508 / ef532_ps.fm
