## Description

This compact magnetic buzzer transducer is designed for externally driven audio output in space-constrained electronics projects. It takes a zero-peak drive signal and produces a single tone at 2.73kHz.The part is intended for surface mount assembly, with solder pad termination and a side port. Its small 9.00mm diameter footprint makes it useful for compact boards that need simple audible feedback, alerts or beeps.Specifications:Driver Circuitry: Transducer, Externally DrivenInput Type: Zero-Peak SignalVoltage - Rated: 3.6VVoltage - Range: 2.5 ~ 4.5VFrequency: 2.73kHzTechnology: MagneticOperating Mode: Single ToneSound Pressure Level (SPL): 83dB @ 3.6V, 10cmCurrent - Supply: 110mAPort Location: SideOperating Temperature: -40°C ~ 85°CMounting Type: Surface MountTermination: Solder PadsSize / Dimension: 0.354" Diameter (9.00mm)Height - Seated (Max): 0.106" (2.70mm)
