BRT1209P-01

Overview

The BRT1209P-01 is an externally driven electro-acoustic transducer designed for audio warning applications. It operates at a nominal voltage of 1.5 VDC with a maximum current draw of 30 mA. The device features a coil resistance of 40 ohms and utilizes PC pin termination for through-hole mounting. Its compact, lightweight construction allows integration into space-constrained equipment.

Feature Summary

• Externally driven piezoelectric design eliminates internal circuitry requirements
• Compact form factor suitable for limited space installations
• Through-hole PC pin termination for standard board mounting

Applications

• Audio indicators in consumer electronics
• Warning devices in portable instruments
• Audible alerts in compact industrial equipment

Procurement Notes

Verify the specific suffix (e.g., -C or -50) against project requirements as variants differ in acoustic output and drive type. Confirm RoHS compliance status with the supplier prior to ordering. Ensure the selected variant matches the required sound pressure level and frequency specifications for the target application environment.

Selection Notes

Select this component when a simple, low-voltage audible alert is needed without complex driving circuits. The 1.5V operation suits battery-powered systems. Consider the 70dB output level for general proximity warnings rather than high-noise environments. Verify mechanical dimensions fit the enclosure constraints.

Part Context

This part belongs to the Intervox BRT series of electro-acoustic transducers. These devices are engineered to reduce arcing and RF noise compared to traditional magnetic buzzers. The series offers various acoustic outputs and drive configurations to meet diverse signaling needs in small-footprint designs.

Replacement Considerations

Direct substitutes include the BRT1209P-01-C for piezo-driven applications requiring similar electrical characteristics. The BRT1209P-01-50 serves as an alternative for magnetic drive requirements. Verify mounting hole patterns and terminal compatibility before swapping.
