PIEZO ALARMS ENCASED EXTERNAL DRIVE (no internal circuitry) PKM Series The piezo alarms described on this page have no “feedback” tab and are particularly suited for the generation of both single tones and the unusual sound effects that are possible with specifically designed driving circuits. These sounds may include musical melodies, insect sounds, etc. All mechanical and electrical ponents are designed to be patible with most standard PC board assembly and wave soldering techniques. Features I Rugged construction I patible with wave soldering techniques I Low cost I High reliability I Variable tone outputs I No EMI APPLICATIONS I Musical toys I Home appliances (microwave ovens, refrigerators, etc.) I munications equipment I puter peripherals and office equipment I Instrumentation, etc. ‚PKM35-4A0 ‚PKM17EW-2001 PIEZO ALARMS Part Number ‚PKM22EPP-4001- ‚PKM22EP-2001 ‚PKM22EP-2001R Sound Pressure Level 75d B@10cm@3Vp-p Oscillating Frequency 4k Hz Operating Voltage 25Vp-p 75d B@10cm@3Vp-p 2k Hz 25Vp-p - 20°C to +70°C - 40°C to +80°C 17,000p F ± 30% at 120Hz - 75d B@10cm@3Vp-p 2k Hz 25Vp-p - 40°C to +125°C - 40°C to +125°C 17,000p F ± 30% at 120Hz - 12.6 75d B@10cm@3Vp-p 4k Hz 25Vp-p - 20°C to +70°C - 30°C to +80°C 9,500p F ± 30% at 1k Hz 32AWG (UL-1685) 72d B@10cm@3Vp-p 2k Hz 7Vp-p max. - 20°C to +70°C - 30°C to +80°C 40,000p F ± 30% at 120Hz 32AWG (UL-1685) Operating Temp.Range - 20°C to +70°C Storage Temp.Range Capacitance Leads DIMENSIONS: mm - 30°C to +80°C 12,000p F ± 30% at 1k Hz - 10.5 4.8 terminal...
