SBM616JR

Overview

The SBM616JR is a piezoelectric buzzer from Mallory Sonalert Products Inc., designed for through-hole mounting. It operates within a voltage range of 6 to 16 VDC and draws a current of 40 mA. The device produces a warble tone at a frequency of 2.8 kHz with a sound pressure level of 78 dBA. It features screw terminals for connection and is housed in a compact form factor suitable for panel or board applications.

Feature Summary

• Piezoelectric transducer technology for reliable audio indication
• Warble tone output for distinct alert signaling
• Screw terminal connections for secure wiring
• Through-hole mounting style for PCB integration

Applications

• Industrial control panels requiring audible alarms
• Electronic equipment status indicators
• Safety warning systems in machinery
• Consumer appliance alert modules

Procurement Notes

Verify the specific suffix 'JR' against the manufacturer's official datasheet to confirm exact acoustic and electrical tolerances. Ensure compatibility with existing panel cutouts and terminal spacing. Confirm RoHS compliance status if required by project specifications. Cross-reference the Mouser part number 539-SBM616JR for accurate ordering details and availability.

Selection Notes

Select this component when a warble tone is preferred over continuous or pulse tones for attention-grabbing alerts. The 6-16 VDC operating range offers flexibility for various DC power supplies. The screw terminal interface simplifies assembly compared to solder-only options. Consider the 78 dBA output level relative to ambient noise requirements in the target application environment.

Part Context

This part belongs to the SBM series of piezoelectric buzzers, which are characterized by their robust construction and clear audio output. The series is commonly used in industrial and commercial applications where reliable audible signaling is critical. The SBM616JR variant specifically targets low-voltage DC systems with standard screw terminal connectivity.

Replacement Considerations

The SC616JWR is an industrial-grade alternative within the same manufacturer's portfolio, offering similar voltage ranges but with different mounting and terminal configurations. Verify dimensional compatibility and acoustic performance before substitution.
