Compact passive stereo buzzer set, 2 pieces, DC 5V, 16 ohm impedance, 12 x 8 mm Key benefits Small footprint and low profile: 12 x 8 mm size fits tight spaces on PCBs and in enclosures where space is limited. Easy electrical connection: two terminals simplify soldering or connector wiring for quick integration into projects and devices. Works with common 5V systems: rated for DC 5V operation, compatible with microcontroller boards and 5V logic circuits. Passive design for flexible tone control: as a passive buzzer it produces sound when driven by an external signal source such as PWM, square waves, or audio drivers, allowing adjustable tones and melodies. Consistent impedance for predictable loading: 16 ohm impedance provides a defined load for driver circuits and helps when matching to amplifiers or controller outputs. Product details Quantity: 2 pieces Voltage: DC 5V Terminals: 2 terminals for straightforward wiring Impedance: 16 ohm Type: passive stereo electronic buzzer Size: 12 x 8 mm Performance and use notes Requires an external drive signal: does not produce sound when connected to DC only. Use PWM, oscillator, or audio output to generate tones. Suitable for low voltage applications and hobby circuits; check driver current capability to ensure proper performance with a 16 ohm load. Typical applications DIY electronics and maker projects: audible alerts, chimes, and custom tone generation controlled by microcontrollers. Alarm and indicator systems: short beeps or tone patterns for status notifications in panels and equipment. Toys and small audio devices: add programmable sound effects or simple melodies where compact size is required. Why choose this buzzer Compact and simple to use with common 5V control sources. Two terminals and defined impedance make integration into prototypes and small products straightforward. Pack of two provides spare or dualchannel options for stereo or multichannel designs. What you get Two passive stereo electronic buzzers, each DC 5V, 16 ohm, 12 x 8 mm, with two terminals for connection. Technical reminder Ensure your driver or controller can supply the required current into a 16 ohm load and provide an appropriate driving waveform to produce sound.
