BRP1407P-20

Overview

The BRP1407P-20 is a passive, externally driven piezoelectric buzzer manufactured by International Components Corp. It operates at a resonant frequency of 4.096 kHz and produces an acoustic output of 80 dB when driven with 10 V at a distance of 10 cm. The device is rated for a maximum supply voltage of 20 V and utilizes a through-hole mounting configuration. Its physical dimensions are 14 mm in diameter by 6.8 mm in height, with a terminal spacing of 13.8 mm. This component is designed for audio warning applications requiring reliable mechanical sound generation without internal drive circuitry.

Feature Summary

• Externally driven piezoelectric transducer design
• Through-hole PC board mounting capability
• RoHS compliant construction

Applications

• General purpose alarm systems
• Audio warning devices
• Siren circuits

Procurement Notes

Verify the specific ordering suffix to ensure correct voltage and dimensional specifications. Confirm RoHS compliance status if required by regulatory standards. Check minimum order quantities which may be set at 100 units by distributors. Ensure the external drive circuit provides the necessary 10 V signal for specified acoustic performance.

Selection Notes

Select this component for applications requiring a passive, high-output audible alert. The 4.096 kHz frequency offers distinct audibility. Ensure the driving electronics can supply the required voltage without exceeding the 20 V maximum rating. Consider the 13.8 mm terminal spacing for PCB layout compatibility.

Part Context

This part belongs to the ICC Intervox line of passive piezoelectric buzzers. These components rely on external oscillators or microcontrollers to generate the drive signal. They are commonly used in industrial and consumer electronics where simple, robust audio indication is needed without the complexity of active driver ICs.

Replacement Considerations

No direct public substitute part numbers are confirmed in available documentation. Verify pinout and dimensional compatibility before substituting with other piezoelectric buzzers from different manufacturers.
