Overview
The SBT12VHCSPPC is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 9 to 12 volts and produces a sound pressure level of 85 decibels at a distance of 10 centimeters when powered at 9 volts. The device functions at a frequency of 2.075 kHz with a current consumption between 15 and 25 milliamperes. It utilizes through-hole PC pin termination for mounting and features a compact size of 44.45 millimeters.
Feature Summary
- Internally driven piezoelectric technology for direct connection
- Ventilation melody sound output configuration
- Through-hole PC pin termination for board installation
Applications
- Medical equipment ventilation status indication
- Industrial control panel signaling
- Consumer appliance operational alerts
Procurement Notes
Verify the specific ventilation melody variant against project requirements, as Mallory offers multiple acoustic profiles within the SBT12 series. Confirm that the through-hole PC pin pitch matches the target PCB layout dimensions. Ensure the operating voltage aligns with the system's 9V to 12V DC supply rails to maintain optimal sound pressure levels and current draw specifications.
Selection Notes
Select this component when a compact, internally driven alarm is required for board-level integration. The 85dB output provides adequate audibility for general industrial and medical applications without excessive power consumption. The PC pin format simplifies assembly compared to screw-terminal or bracket-mounted alternatives, making it suitable for high-volume manufacturing environments.
Part Context
This part belongs to the SBT12 series of industrial-grade audio indicators from Mallory Sonalert. The series is designed for reliability in demanding environments, featuring RoHS compliance and adherence to IEC standards. The SBT12VHCSPPC specifically denotes the ventilation melody variant within this family, distinguishing it from cardiac, perfusion, or general purpose tones available in other model numbers.
Replacement Considerations
Direct substitutes include SBT12GHFL (General), SBT12CMFL (Cardiac), and SBT12PHFL (Perfusion) if different acoustic patterns are acceptable. Verify that the replacement maintains the same 9-12VDC input range and through-hole PC pin mechanical footprint to ensure compatibility with existing PCB designs.
