Overview
The AT-0927-TT-5V is an externally driven magnetic transducer manufactured by PUI Audio, Inc. It operates at a nominal voltage of 5 V with a current consumption of 80 mA. The device features a resonant frequency of 2.73 kHz and produces a sound pressure level of 85 dB measured at 10 cm distance. Designed for through-hole mounting via PC pins, it has a maximum operating temperature range of -40°C to 85°C. The component utilizes a single-tone working mode and accepts zero-to-peak input signals.
Feature Summary
- Externally driven magnetic transducer design
- Through-hole mounting configuration using PC pins
- Single-tone operational mode
Applications
- Electronic indicators
- Alarm systems
- Audible signaling devices
Procurement Notes
Verify the specific suffix designation when ordering, as variants such as AT-0927-TT-5-R exist with different electrical characteristics like 1.5 V operation. Confirm that the through-hole package type matches the target PCB layout requirements. Ensure the external drive circuitry can supply the required 80 mA current at the specified 5 V operating voltage for proper functionality.
Selection Notes
Select this model when a through-hole solution is required instead of surface mount alternatives like the SMT series. Compare against the AT-0927-TT-5-R variant if lower voltage operation is needed, noting the distinct voltage ratings. Ensure the application environment stays within the specified -40°C to 85°C temperature range for reliable performance.
Part Context
This component belongs to the AT-0927 series of electro-mechanical buzzers from PUI Audio. It shares similar acoustic specifications with other models in the family but differs in mounting style and voltage rating. The series offers both surface mount and through-hole options to accommodate various manufacturing processes.
Replacement Considerations
The AT-0927-TT-5-R is a related variant but operates at 1.5 V. Direct replacement requires verifying voltage compatibility. Surface mount equivalents like the SMT-0927-T-2-R require PCB redesign due to different mounting technologies.
