Core Electrical and Acoustic Specifications<\/h2>\n
This 12mm long\u2011pin piezoelectric buzzer has a resonant frequency of 4.0±0.5KHz<\/strong>, rated peak\u2011to\u2011peak voltage of 5Vp\u2011p<\/strong>, and an operating voltage range of 1\u201125V(Vp\u2011p). Its maximum current consumption is 3mA, which helps reduce power consumption for low\u2011power electronic systems. Under standard test conditions of 5Vp\u2011p, 1\/2 duty square wave at 4.0KHz, the minimum sound output reaches 80dB when measured at 10cm distance, providing clear audible alerts for compact equipment. The capacitance value tested at 120Hz is 14±30%nF. All parameters are verified under standard test environment: temperature 25±1\u2103, humidity 45%\u201175%, air pressure 86\u2011106kPa.<\/p>\n One of the most prominent features of this buzzer is its long pin design<\/strong>, which provides enough length for convenient PCB insertion, reliable soldering and stable board connection. The buzzer has an outer diameter of φ12±0.5mm and a total height of 6.5±0.5mm. The long pins help improve assembly flexibility, especially for through\u2011hole installation, wave soldering and projects requiring extra soldering space. The housing material is PBT, and the product weight is only 0.7g. For environmental performance, operating temperature ranges from \u201120\u2103 to +70\u2103, while storage temperature ranges from \u201130\u2103 to +80\u2103. The specification also provides complete lead\u2011free soldering parameters for reflow soldering, wave soldering and manual soldering.<\/p>\n This 12mm long\u2011pin piezoelectric buzzer is suitable for compact electronic products, PCB through\u2011hole assembly, small household appliances, control panels, alarm modules and other devices requiring easy insertion and stable soldering. It supports both small\u2011batch sample evaluation and large\u2011volume bulk procurement. Backed by stable production capacity, strict quality control and factory\u2011direct pricing, this long\u2011pin buzzer is a practical choice for global electronic purchasers who need reliable through\u2011hole mounting performance.
