SBS12DMHFPPC

Overview

The SBS12DMHFPPC is a piezoelectric buzzer from the Mallory Sonalert SBW series, designed for PCB mounting. It operates on a DC voltage range of 9 to 12 V with a current rating of 630 mA. The device features a round shape with a diameter of 44.45 mm and a height of 15 mm. It delivers a sound pressure level between 85 dB and 95 dB across a frequency range of 150 Hz to 4 kHz. Operating temperatures span from -30°C to +65°C, and it utilizes solder terminals for connection.

Feature Summary

• Internally driven indicator circuitry for simplified integration
• Piezoelectric technology for reliable audio signaling
• Cardiac alarm specification compliance

Applications

• Medical device cardiac alarms
• Ventilator failure alerts
• General medical equipment indicators

Procurement Notes

Verify the specific suffix PPCC against the official Mallory Sonalert datasheet to confirm terminal configuration and compliance certifications. Ensure the input power supply matches the 9-12V DC requirement and that the PCB layout accommodates the 44.45mm diameter and solder termination style. Cross-reference the RoHS status with current regulatory requirements for your target market.

Selection Notes

Select this component when a high-intensity cardiac alarm signal is required within strict spatial constraints. The internally driven nature reduces external component count compared to passive transducers. Consider the 630 mA current draw for power budget calculations and ensure the operating environment stays within the specified -30°C to +65°C temperature range.

Part Context
