Overview
The PT-2707 is an externally driven piezo transducer manufactured by Soberton Inc. It operates within a voltage range of 1V to 30V and utilizes through-hole mounting with PC pins. The device features a resonant frequency of 2kHz and delivers a sound pressure level of 70dB at 3V measured at a distance of 10cm. Current consumption is specified at 1mA under standard operating conditions. The component is designed for audio signaling applications and is RoHS compliant.
Feature Summary
- Externally driven piezoelectric transducer design
- Through-hole mounting configuration with PC pins
- RoHS compliant construction
Applications
- Audio signaling systems
- Alarm circuits
- Buzzer assemblies
Procurement Notes
Verify the specific datasheet version from Soberton Inc. to confirm mechanical dimensions and electrical tolerances. Ensure that the through-hole footprint matches the target PCB layout. Confirm RoHS compliance status if required by regulatory standards. Cross-reference pin configurations with assembly documentation to prevent installation errors.
Selection Notes
Select this component for applications requiring a simple, externally driven piezo buzzer with through-hole compatibility. Consider the 2kHz resonant frequency and 70dB output level for audible alert requirements. Evaluate the 1-30V operating range against available drive voltages. Verify space constraints relative to the physical dimensions provided in official documentation.
Part Context
This part belongs to the audio products category, specifically within alarms, buzzers, and sirens. Soberton Inc. manufactures this transducer as a standalone acoustic output device. It serves as a direct replacement for similar piezo buzzers in legacy designs requiring through-hole integration and external driving signals.
Replacement Considerations
Consult official Soberton Inc. documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers without verifying electrical and mechanical specifications.
