{"title":"Surface Mount Magnetic Buzzer Transducer","handle":"buzzer-audio-magnetic","url":"/products/buzzer-audio-magnetic","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)","vendor":"SparkFun","product_type":"Buzzer Transducer","in_stock":true,"options":[],"variants":[{"id":16439,"title":"Default Title","sku":"SF-COM-31569","mpn":"COM-31569","price":6.68,"on_sale":false,"in_stock":true,"available_quantity":1000}],"documents":[{"title":"Supplier page — sparkfun.com","type":"supplier_description","type_label":"Supplier Description","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDr3wDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--765d520dea0ef27fa74bf1d9286dc040651b1a63/buzzer-audio-magnetic-sparkfun-com-2026-08-17.pdf","link":false,"file_extension":"PDF","file_size":521032,"description":"Snapshot of https://www.sparkfun.com/buzzer-audio-magnetic.html (captured 17 Aug 2026)"},{"title":"Surface Mount Magnetic Buzzer Transducer Datasheet","type":"datasheet","type_label":"Datasheet","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDsHwDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--fc2241ff8a810a726790567642ac54ad5319751e/cbt-09427-smt-tr.pdf","link":false,"file_extension":"PDF","file_size":500959,"description":"Electrical and mechanical specifications for the SMT magnetic buzzer."}]}
