Passive Buzzer 5V 42Ω 2048Hz 12×8.5mm The Passive Buzzer 5V 42Ω 2048Hz 12×8.5mm is a compact electromagnetic sound component designed for applications that require programmable tone generation. Unlike active buzzers, this device does not contain an internal oscillator and must be driven by an external signal such as a PWM waveform from a microcontroller. Features: Passive buzzer requiring external drive signal. Operates at 5V nominal voltage. Coil resistance approximately 42Ω. Resonant frequency around 2048Hz. Supports PWM and tone signal input. Compact size for space-constrained designs. Specifications: Parameter Value Type Passive Electromagnetic Buzzer Rated Voltage 5V Operating Voltage 3V to5V Rated Current ≤30mA Coil Resistance 42Ω Resonant Frequency 2048Hz Sound Output ≥85dB Mounting Type Through Hole Dimensions 12mm × 8.5mm Pin Pitch 6mm Applications: Microcontroller alert systems (Arduino, embedded systems). Alarm and notification circuits. DIY electronics projects. Sound indication in control panels. Educational electronics experiments. Timer and warning systems. Package Include: 1x Passive-Buzzer 5V 42Ω 2048Hz 12×8.5mm Certifications
