Overview
The SBT5TLHSPPC is a piezoelectric buzzer from the Mallory Sonalert SBT series, designed for through-hole mounting. It operates within a voltage range of 3.3 to 5 VDC and draws a supply current of 27 mA. The device produces a sound pressure level of 90 dBA at a distance of 10 cm. It features an internal driver circuit and emits a continuous tone at a frequency of 4.4 kHz. The unit measures 44.45 mm in diameter and is rated for operation between -40°C and +85°C.
Feature Summary
- Complies with IEC 60601-1-8 medical alarm standards
- Includes integrated internal drive circuitry
- Capable of generating high-priority audible alerts
Applications
- Medical device alarm systems
- Cardiac monitoring equipment
- Ventilator status indicators
- Hospital patient care units
Procurement Notes
Verify that the specific suffix indicates compliance with required regional safety certifications. Confirm the operating voltage matches the system design before integration. Ensure the through-hole package dimensions fit the target PCB layout. Check for any recent product change notifications affecting acoustic performance or material composition.
Selection Notes
Select this component when a loud, high-priority medical alarm is required. The 90 dBA output ensures audibility in noisy clinical environments. The internal driver simplifies interface requirements compared to passive buzzers. Verify that the 3.3V to 5VDC input aligns with the available logic levels in the host system.
Part Context
This part belongs to the SBT series of surface-mount and through-hole transducers. The series focuses on medical applications requiring strict adherence to international safety standards. Mallory Sonalert designs these components specifically for critical audio signaling in healthcare settings.
Replacement Considerations
Consult official substitution lists for equivalent IEC-compliant medical buzzers. Verify that any alternative maintains the same 90 dBA output and 4.4 kHz frequency. Ensure the replacement supports the same 3.3V to 5VDC operating range.
