BRP1708P-30

Overview

The BRP1708P-30 is an externally driven piezoelectric alarm transducer manufactured by Intervox. It operates with a maximum supply voltage of 30 V peak-to-peak and delivers a sound pressure level of 95 dB at 30 cm when driven by a 10 V peak-to-peak signal. The device features a resonant frequency of 4500 Hz with a tolerance of +/- 500 Hz. It utilizes through-hole PC pin termination for mounting and functions within a temperature range of -20 to 60 degrees Celsius.

Feature Summary

• Externally driven piezoelectric transducer design
• High sound output capability of 95 dB at specified distance
• Through-hole PC pin termination for secure mounting

Applications

• Audio warning devices
• Alarm systems
• Notification circuits

Procurement Notes

Verify the specific drive requirements, as this component is externally driven and requires an external oscillator or microcontroller to generate the necessary AC signal. Confirm that the operating voltage does not exceed the 30 V peak-to-peak maximum rating. Ensure the PCB layout accommodates the through-hole PC pin package dimensions and spacing. Check environmental specifications if operation outside the -20 to 60 C range is required.

Selection Notes

Select this component when a high-intensity audible alert is needed without internal driving circuitry. It is suitable for applications where space constraints preclude self-driven buzzers but allow for external signal generation. Consider the 4500 Hz resonant frequency for tone requirements. Evaluate the 95 dB output against ambient noise levels to ensure audibility.

Part Context

This part belongs to the Intervox piezoelectric audio product line, designed for reliable acoustic signaling. Unlike self-driven units, it relies on external drivers, offering flexibility in frequency modulation and duty cycle control. It serves as a direct replacement for similar externally driven piezo alarms in industrial and consumer electronics.

Replacement Considerations

Direct substitutes must match the 30 V max rating, 95 dB output, and through-hole pin configuration. Verify resonant frequency compatibility if tone specificity is critical. Cross-reference with other Intervox externally driven models for mechanical fit.
