PB-12N23P-03Q

Overview

The PB-12N23P-03Q is a magnetic buzzer indicator manufactured by Mallory Sonalert Products Inc. It operates on a DC input with a rated voltage of 3 V and a supply current range of 30 mA. The device produces a continuous tone at a frequency of 2.3 kHz, achieving a sound pressure level of 85 dB measured at 3 V and 10 cm distance. Designed for through-hole mounting, it features PC pins for termination. The unit is sealed and suitable for board mount applications within the specified electrical parameters.

Feature Summary

• Internally driven magnetic buzzer design
• Sealed construction for environmental protection
• Continuous tone output capability

Applications

• Electronic equipment status indication
• Alarm systems requiring audible alerts
• Control panel audio feedback

Procurement Notes

Verify the specific operating voltage requirement against the system design, as this component is rated for 3 V operation. Confirm that the PCB layout accommodates the through-hole PC pin spacing and dimensions. Ensure the application environment does not exceed the operational limits defined in the official datasheet to maintain performance reliability.

Selection Notes

Select this model when a low-profile, internally driven magnetic buzzer is required for 3 V DC systems. It is appropriate for designs needing a compact form factor with through-hole termination. Consider the 85 dB acoustic output and 2.3 kHz frequency for audibility requirements in the intended enclosure or environment.

Part Context

This component belongs to the PB series of audio indicators from Mallory Sonalert. The series offers various voltage options and acoustic outputs. The PB-12N23P-03Q specifically addresses needs for 3 V operation with a standard magnetic transducer type, providing a reliable solution for general-purpose audible signaling in consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes within the same series offering different voltage ratings if system power rails differ. Verify mechanical compatibility including mounting hole patterns and terminal types before substituting with other manufacturers' magnetic buzzers.
