PB-3025NL

Overview

The PB-3025NL is an externally driven piezoelectric buzzer manufactured by Soberton Inc. It operates at a nominal voltage of 12V with a current consumption of 15mA. The device produces a sound pressure level of 90dB at 12V and has a resonant frequency of 3.7kHz. It features a 29mm diameter flange design for panel mounting, utilizing wire leads for electrical connection.

Feature Summary

• Washable reflow type construction suitable for automated assembly processes
• Externally driven piezoelectric transducer design
• Panel mount configuration with integrated flange

Applications

• Industrial control panels requiring audible alerts
• Appliance status indication systems
• Security alarm housings

Procurement Notes

Verify the specific acoustic output requirements against the 90dB specification at 12V. Confirm that the 3.7kHz resonant frequency aligns with the target application's audibility needs. Ensure the external driver circuit can supply the required 15mA current. Check compatibility with washable reflow soldering processes if used in such manufacturing environments.

Selection Notes

Select this component when a robust, panel-mountable piezo buzzer is needed for 12V systems. The flange design simplifies mechanical installation compared to non-flanged alternatives. Consider the 3.7kHz frequency response for optimal human hearing perception in noisy environments. Verify that the wire lead termination method fits the available PCB or harness layout constraints.

Part Context

This part belongs to the PB series of piezo audio buzzers from Soberton Inc. The series offers various voltages and frequencies. The PB-3025NL specifically targets applications requiring a balance of high volume output and standard panel mounting dimensions.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the 12V rating, 3.7kHz frequency, 90dB SPL, and 29mm flange diameter specifications exactly.
