PB-4314

Overview

The PB-4314 is an externally driven piezoelectric buzzer manufactured by Soberton Inc. It operates at a nominal voltage of 12V with a current draw of 8mA. The device features a resonant frequency of 2.8kHz and produces a sound pressure level of 90dB when measured at a distance of 10cm. It utilizes through-hole mounting with PC pins for circuit board integration.

Feature Summary

• Externally driven piezoelectric transducer design
• Through-hole mounting configuration with PC pins
• Non-washable type construction

Applications

• Audio indication in electronic equipment
• Alarm systems requiring audible alerts
• Industrial control panel signaling

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required mounting styles and electrical characteristics. Confirm that the non-washable designation aligns with your manufacturing process requirements, as this component is not suitable for standard wave or selective soldering washes without potential damage.

Selection Notes

Select this component for applications requiring a simple, externally driven audio signal source. Ensure the driving circuit can supply the specified 8mA current at 12V. Consider the 2.8kHz resonant frequency for acoustic matching purposes and verify that the 90dB output level meets the environmental noise requirements of the target application.

Part Context

This part belongs to the PB Series of piezoelectric buzzers from Soberton Inc., which are designed for general-purpose audio indication. The series includes various models with different voltage ratings and form factors, all sharing common piezoelectric technology principles for reliable sound generation in consumer and industrial electronics.

Replacement Considerations

Direct substitutes may include other 12V piezo buzzers with similar 2.8kHz resonance and 90dB SPL ratings. Verify mechanical dimensions and pinout compatibility before substitution. Alternative brands offering through-hole piezo buzzers with comparable electrical specifications should be evaluated for functional equivalence.
