ST-0503 Indicator/Buzzer

ST-0503 Indicator/Buzzer

Soberton’s ST-0503 is the smallest indicator/buzzer currently offered in their extensive audible offering. It offers a low-profile (3 mm) small-size transducer that is perfect for any tight space applications. Furthermore the SMD footprint is small which trims board space/size. Even though the transducer is miniature-size, it still offers a very audible 75 dB at 10 cm. This product is rated at 3 V with a frequency of 4 kHz.
