Overview
The SBT12CLMSPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It features internal drive circuitry and accepts DC input within a voltage range of 9V to 25V. The device operates at a frequency of 2.075kHz with a sound pressure level of 85dB measured at 9V and 10cm distance. Power consumption ranges from 15mA to 25mA. It utilizes through-hole mounting with PC pin termination and has dimensions of 44.45mm.
Feature Summary
- Internally driven piezoelectric technology for direct connection
- Through-hole mounting configuration with PC pins
- High sound pressure output relative to power consumption
Applications
- Medical equipment audio indicators
- Industrial control panel alarms
- Consumer appliance status alerts
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct voltage and acoustic specifications. Confirm that the through-hole PC pin pitch matches the target PCB layout. Check for RoHS compliance status if required by project regulations. Ensure the operating temperature range meets environmental requirements.
Selection Notes
Select this component when a high-intensity audible alert is required in a compact form factor. The internal driver simplifies circuit design by eliminating external oscillators. Verify that the 9V-25V DC input aligns with the system power supply. Consider the 44.45mm diameter for panel cutout or chassis space constraints.
Part Context
This part belongs to the SBT series of industrial-grade buzzers from Mallory Sonalert. The series is designed for robust performance in demanding environments. It shares the internal drive architecture common to the brand's indicator line, ensuring consistent reliability across various audio signaling applications.
Replacement Considerations
Cross-reference with other Mallory SBT series models for similar acoustic output. Verify mechanical compatibility before substituting with non-Mallory brands due to potential differences in pin spacing and housing dimensions.
