BRT1207P-01-SEHB

Overview

The BRT1207P-01-SEHB is an externally driven electro-acoustic transducer designed for PC board mounting. It operates on a rated voltage of 1.5 VDC with a functional range of 1 to 2V. The device produces a sound pressure level of 75dB at a distance of 10cm and functions at a frequency of 2731Hz. It features a two-pin termination, measures approximately 6.5mm in width, and weighs 22 grams. The unit is RoHS compliant and suitable for continuous operation within a temperature range of -20°C to +60°C.

Feature Summary

• Externally driven electro-acoustic transducer design
• Compact and lightweight construction for space-constrained equipment
• RoHS compliant manufacturing standards

Applications

• Audio warning devices
• Alarms and buzzers
• Sirens

Procurement Notes

Verify the specific suffix SEHB against official datasheets to confirm the 75dB SPL rating and 2731Hz frequency, as other suffixes in the BRT1207P series may differ significantly in acoustic output or electrical characteristics. Ensure the application environment remains within the specified -20°C to +60°C operating temperature range to maintain performance integrity.

Selection Notes

Select this component when a low-voltage, externally driven transducer is required for audible signaling. The 1.5V rating suits battery-powered or low-voltage logic systems. Consider the 75dB output level relative to ambient noise requirements and verify that the external driver circuit can supply the necessary current without exceeding the device's thermal limits.

Part Context

This part belongs to the Intervox BRT1207P series of small, lightweight electro-acoustic transducers. These devices are engineered for integration into various electronic equipment where size and weight are critical constraints. The series offers multiple variants differentiated by acoustic output and frequency specifications.

Replacement Considerations

Cross-reference with BRT1207P-01-SEHA if a higher 80dB output is acceptable, noting the frequency difference. Verify pin compatibility and physical dimensions before substituting with other BRT1207P variants.
