SBT5PLMSPPC

Overview

The SBT5PLMSPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates within an IEC voltage range of 3.3 to 5 VDC and produces a sound pressure level of 90 dB. The device features a perfusion-specific audio tone, suitable for medical equipment applications. It is designed for through-hole mounting on printed circuit boards and complies with RoHS standards. The component is part of the SBT series, which includes various acoustic profiles for different alarm indications.

Feature Summary

• Generates a specific perfusion alarm tone for medical device signaling
• Operates on low DC voltage supply ranging from 3.3V to 5V
• Provides high volume output at 90 dB for clear auditory alerts
• Constructed with lead-free materials compliant with environmental regulations

Applications

• Medical infusion pump alarms
• Ventilator status indicators
• Patient monitoring system alerts
• Hospital bed control panels

Procurement Notes

Verify the exact acoustic profile matches the required perfusion tone specification before integration. Confirm that the 3.3-5VDC operating range aligns with the target circuit design. Ensure the through-hole package dimensions fit the PCB layout constraints. Check for updated compliance documentation regarding RoHS directives if sourcing from new distributors.

Selection Notes

Select this component when a distinct perfusion alarm sound is required in low-voltage medical systems. Compare against other SBT series variants such as SBT5DMFL or SBT5CMFL if different alarm tones like drug-fluid or cardiac are needed instead. Consider the 90 dB output level relative to ambient noise requirements in the intended enclosure.

Part Context

This part belongs to the SBT series of surface-mount and through-hole piezo buzzers from Mallory Sonalert. The series offers various standardized alarm tones including general, failure, and medical-specific sounds. These components are widely used in industrial and healthcare electronics requiring reliable audible feedback.

Replacement Considerations

SBT5PLMFPPC shares the same perfusion tone and electrical specifications but may differ in packaging or minor mechanical details. Verify pinout compatibility and acoustic performance equivalence before substitution.
