HCM0903LX-27

RYD HCM0903LX-27 is an Active Electromagnetic Buzzer with Φ9×5.5mm dimensions, 3V DC rated operation, and 85dB continuous tone output at 2700Hz. This Active Electromagnetic Buzzer features a built-in driver circuit; a simple two-wire DC connection produces immediate audible output without external oscillator or timing components. Tin-plated brass leads are qualified for 260°C wave soldering up to 5 seconds, with manual rework at 350°C for up to 5 seconds also supported. Operating voltage range is 2–5V DC with 30mA maximum current draw. PPO housing in black finish. Rated −20 to +70°C. Suited to high-throughput PCB assembly lines using wave-solder processes in consumer electronics, industrial control boards, and smart home modules. RoHS compliant materials. Customization available: connection method adaptation and parameter tuning per customer requirement.
