The PUI Audio AT-1220-TT-10-R is an electromagnetic buzzer transducer designed for through-hole PCB mounting. It operates at a resonant frequency of 2.048 kHz with a sound pressure level of 85 dBA. The device accepts a supply voltage range of 1 V to 2 V and draws a current of 20 mA. Its impedance is not explicitly listed in the provided source data, but it features solder pin termination. The unit measures 12 mm in length and width, with a height of approximately 9.5 mm.
Verify the exact operating voltage requirements against your circuit design, as the datasheet indicates a range of 1 V to 2 V. Confirm that the 20 mA current draw is supported by your power supply. Ensure the PCB footprint matches the 12 mm x 12 mm dimensions and 9.5 mm height clearance. Check RoHS compliance documentation if required for your manufacturing standards.
Select this component when a specific 2.048 kHz tone is required rather than a broad-spectrum buzz. Compare its 85 dBA output against louder alternatives like the AT-1224-TWT-5V-2-R if higher volume is needed. Consider the lower voltage operation (1-2 V) compared to standard 3 V or 5 V buzzers for low-power applications.
This part belongs to the AT series of transducers from PUI Audio. It is distinct from piezoelectric variants and other electromagnetic models in the lineup. The suffix '10' typically denotes specific electrical characteristics within the series, differentiating it from the base AT-1220-TT-R model.
The AT-1220-TT-R is a similar through-hole electromagnetic buzzer in the same series. Verify if the current rating and voltage tolerance of the base model meet your specific circuit constraints before substitution.
