This piezoelectric sounder element consists of a metal disc that has a special ceramic material bonded to it that physically bends when voltage is applied to it.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"476\"\u003e\n\u003ccolgroup\u003e \u003ccol width=\"165\"\u003e \u003ccol width=\"311\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr height=\"21\"\u003e\u003ctd colspan=\"2\" height=\"21\" class=\"xl65\" width=\"476\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e30Vpp Max.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eRated Voltage\u003c\/td\u003e\n\u003ctd\u003e5Vpp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eResonant Frequency\u003c\/td\u003e\n\u003ctd\u003e750 ±250Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eCapacitance\u003c\/td\u003e\n\u003ctd\u003e70nF ±30% @ 120Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e1.5mA Max. @ 5V⎓\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eSound Pressure Level\u003c\/td\u003e\n\u003ctd\u003eMin. 87dB @ 5V⎓, 10cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e14 × 60mm (44mm Wide w\/o Mounting Ears)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eMounting Centers\u003c\/td\u003e\n\u003ctd\u003e52mm (Hole Diameter 3.5mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eWire Gauge\u003c\/td\u003e\n\u003ctd\u003e28 AWG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"21\"\u003e\n\u003ctd height=\"21\"\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20° to 70°C (-4° to 158°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cbr\u003eDirect drive transducer devices do not have any included DC circuitry, so the user must apply a sine or square wave with the appropriate rated frequency. A square wave will typically result in more sound level than a sine wave. The higher the peak-to-peak voltage applied (up to the maximum rated voltage), the higher the resulting sound level.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2082\/9857\/files\/2731171_specs.pdf?1359\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"RadioShack","offers":[{"title":"Default Title","offer_id":35659105665181,"sku":"2731171","price":4.0,"currency_code":"NOK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0459\/0521\/5645\/products\/2731171-1.png?v=1597322543","url":"https:\/\/thechivery321231-com.myshopify.com\/products\/87db-piezoelectric-audio-transducer","provider":"thechivery321231.com","version":"1.0","type":"link"}
