Overview
The AT-1220-TT-3V-HT-R is an externally driven electromagnetic transducer manufactured by PUI Audio. It operates within a voltage range of 2 to 5 volts and functions at a frequency of 2 kHz. The device produces a sound pressure level of 80 dBA when measured at 3 volts and a distance of 10 cm. It draws a supply current of 80 mA during operation. The component utilizes magnetic technology for sound generation and is designed for through-hole mounting on printed circuit boards.
Feature Summary
- Externally driven electromagnetic design for flexible control
- High-temperature variant suitable for extended thermal environments
- Through-hole termination for secure board integration
Applications
- Industrial equipment status indication
- Consumer appliance alert systems
- Medical device auditory signaling
Procurement Notes
Verify the specific high-temperature rating requirements against your application's operational limits before procurement. Confirm that the 80 mA current draw is supported by your power supply infrastructure. Ensure the through-hole footprint matches your PCB layout specifications. Check for RoHS compliance documentation if required by your manufacturing standards. Validate the 2 kHz operating frequency aligns with your acoustic design goals.
Selection Notes
Select this component when an externally driven buzzer is preferred over self-excited types for precise frequency control. The high-temperature rating makes it suitable for applications exceeding standard commercial temperature ranges. Consider the 80 mA current consumption when designing power management circuits. The 2 kHz frequency provides a distinct audible tone suitable for attention-grabbing alerts in noisy environments.
Part Context
This part belongs to PUI Audio's AT series of electromagnetic transducers. The 'HT' suffix indicates a high-temperature variant, distinguishing it from standard commercial grade components. The series offers various voltage and frequency options to meet diverse audio signaling needs across industrial and consumer sectors.
Replacement Considerations
Direct substitutes include the AT-1220-TT-3V-2-R for standard temperature applications or the AT-1220-TT-R for general purpose use. Verify mechanical dimensions and electrical characteristics match before substitution.
