BRP1408P-12-CS

Overview

The BRP1408P-12-CS is a self-oscillating piezoelectric buzzer manufactured by International Components Corp. It operates on a rated voltage of 12 VDC with a continuous current draw of 7 mA. The device produces a sound pressure level of 80 dB at 10V measured from 10 cm distance. Its resonant frequency is specified at 4000 Hz with a tolerance of ±500 Hz, operating within a range of 3 to 16 VDC. The unit features through-hole PC pins for mounting and has physical dimensions of 13.8 mm diameter by 7.6 mm height. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Internally driven piezoelectric design eliminates the need for external oscillators
• Self-oscillating capability generates continuous tone directly from DC supply
• Through-hole pin configuration facilitates standard PCB integration

Applications

• Fire alarm systems
• Burglar alarm indicators
• Smoke detector audio output

Procurement Notes

Verify the specific suffix CS against manufacturer documentation to confirm packaging and terminal type variations. Ensure the 12V rating matches system requirements. Confirm lead times and availability status as active components may have supply constraints. Cross-reference datasheet revision dates for updated electrical characteristics.

Selection Notes

Select this component when a compact, internally driven audible indicator is required. The 12V rating suits standard low-voltage control circuits. Consider the 80dB SPL for environments requiring moderate noise levels. Verify spatial constraints against the 13.8mm diameter and 7.6mm height dimensions.

Part Context

This part belongs to the piezoelectric buzzer category from International Components Corp. It is designed for general-purpose audible signaling in electronic devices. The series offers various voltage and size options for different application needs.

Replacement Considerations

Check for direct substitutes with identical 12V rating, 4kHz frequency, and 80dB SPL. Verify mechanical footprint compatibility for through-hole mounting. Ensure operating temperature ranges match environmental conditions.
