BRT1209P-12-C

Overview

The BRT1209P-12-C is an externally driven magnetic electro-acoustic transducer manufactured by Intervox. It operates at a rated voltage of 12V DC with a current consumption of 30mA. The device produces a sound pressure level of 85dB at 10cm and features a resonant frequency of 2.3kHz. Designed for through-hole mounting via PC pins, it functions within a temperature range of -20°C to +70°C.

Feature Summary

• Externally driven magnetic design eliminates internal circuitry complexity
• Compact form factor suitable for space-constrained equipment installations
• Through-hole PC pin configuration ensures secure mechanical mounting

Applications

• Audible feedback systems in industrial control panels
• Alarm indicators in telecommunications infrastructure
• Status signaling in compact electronic devices

Procurement Notes

Verify the specific suffix 'C' corresponds to the through-hole PC pin variant rather than surface mount or other packaging options. Confirm that the application circuit provides external drive signals compatible with the 30mA current rating. Ensure operating temperatures remain within the specified -20°C to +70°C range for reliable performance.

Selection Notes

Select this component when an externally driven magnetic transducer is required for high-volume audible signaling. Compare against piezoelectric alternatives if internal drive circuits are preferred. Evaluate spatial constraints against the 12mm diameter and 9.5mm height dimensions. Consider the 85dB output level relative to ambient noise requirements.

Part Context

This part belongs to the INTERVOX BRT series of ultra-small electro-acoustic transducers. These devices are engineered to eliminate arcing and RF noise common in traditional buzzers. The series includes variants with different voltage ratings and drive configurations, all sharing a compact footprint designed for limited space applications.

Replacement Considerations

Cross-reference with ICC/Intervox BRT1209P-06-C for lower voltage applications requiring similar acoustic output. Verify compatibility with existing PCB layouts due to the specific through-hole pin spacing. Ensure replacement units maintain the same externally driven magnetic topology to preserve electrical characteristics.
