产品特点 FEATURES

1 Magnetic buzzer transducer with external drive design, requiring external square wave signal to generate sound

2 Surface Mount Technology (SMT) mounting type for easy integration into PCB assemblies

3 RoHS compliant, meeting environmental protection standards

4 Washable structure, suitable for applications that need periodic cleaning

5 Rated voltage:1.5Vp-p (typical), operating voltage range:1.2-2.0Vp-p

6 Rated frequency:2.4kHz (typical)

7 Sound pressure level:85dBA (typical) at 10cm distance with rated voltage and10% duty cycle

8 Coil resistance:16Ω (typical), range:13.0-19.0Ω

9 Physical dimensions:12.8×8.8×7.0mm, lightweight at2.0g

10 Housing material:PPS (S-206) with good heat and chemical resistance

11 Terminal:SMT type with Au plating for reliable soldering and electrical conductivity

12 Operating temperature range:-20~70°C, storage temperature range:-30~85°C

13 Max current consumption:80mA at rated voltage,2.4kHz square wave,10% duty cycle

使用场景 APPLICATIONS

1 Consumer electronics:Smart home devices (smoke detectors, thermostats, smart plugs) for alert notifications

2 Industrial equipment:Portable measuring instruments, control panels, automation systems for status indication (error alerts, power on/off signals)

3 Medical devices:Non-critical medical equipment (blood glucose monitors, digital thermometers) for user feedback

4 Automotive interior electronics:Dashboard warning systems, parking sensors for audio alerts

5 IoT devices:Wearable gadgets, wireless sensor nodes for low-power alert signals

注意事项 PRECAUTIONS

1 External drive required:This buzzer is not self-driven; it needs an external square wave signal (2.4kHz typical,10% duty cycle) to work, DC voltage alone cannot produce sound

2 Soldering guidelines:Follow recommended reflow soldering profile (peak temperature:260°C, duration:20-40 seconds) to avoid damage

3 Storage conditions:Store in environment with temperature -30~85°C and relative humidity ≤60%; if stored beyond48 hours in high humidity, dry at40°C for24 hours before soldering

4 Application restriction:Do not use in critical systems (e.g., life support equipment, safety-critical industrial control systems) as per manufacturer's warning

5 Cleaning:Use methods compatible with PPS material and Au-plated terminals; avoid harsh chemicals

6 Voltage range:Operate within1.2-2.0Vp-p to prevent coil damage or reduced lifespan
