10pcs DC 5V 2Terminal 16ohm Passive Stereo Electronic Buzzer 12x8mm Key benefits Readytoinstall pack of 10 units for multiple projects or spares. Compact 12x8mm size saves board space and fits tight enclosures. 2terminal passive design allows direct soldering to PCBs or simple wiring. 16 ohm impedance and DC 5V rating deliver predictable acoustic load for common driver circuits. Passive stereo operation gives flexibility to generate tones using external signals or microcontroller outputs. Why you need it Provides a reliable audible indicator when you need simple tones, beeps, or alerts. Small form factor and standard terminal layout make integration fast and repeatable. Having a 10piece set reduces procurement time for prototyping, small production runs, or classroom kits. How it solves problems and what makes it stand out Solves the need for compact, lowimpedance sound transducers that work with many driver circuits. Passive construction avoids internal drive electronics, enabling custom tone generation and volume control through the driving waveform. Uniform impedance across the pack helps ensure consistent behavior across channels or devices. Important attributes Function: Passive electronic buzzer for audible signals when driven by an external audio or square wave source. Power and electrical: Rated for DC 5V operation; 16 ohm impedance. Connections: Two terminals for straightforward soldering or connector attachment. Size: Compact 12x8mm housing suitable for dense PCB layouts and small enclosures. Performance: Designed for clear, repeatable tones when paired with typical driver circuits or microcontroller outputs. Practical use scenarios DIY electronics and maker projects: Add beeps, alerts, or simple melodies to microcontroller projects, educational kits, or prototypes. Consumer device alerts: Integrate as status or warning indicators in small appliances, remote controls, or handheld devices. Security and alarm systems: Use as a compact audible element for local alarms, timers, or notification modules. What to consider As a passive buzzer, it requires an external driving signal or oscillator to produce sound. Direct DC without a driving waveform will not generate tones. Ensure driver capability matches the 16 ohm load to avoid overstressing the driving circuit. Contents of the pack 10 passive stereo electronic buzzers, each DC 5V, 2 terminals, 16 ohm impedance, 12x8mm. This component is suited to electronics hobbyists, engineers, and smallscale manufacturers who need a compact, consistent audible transducer for tone generation and alerts.
