MSS300R

Speakers Overview

The MSS300R is an octagonal speaker manufactured by Mallory Sonalert, designed for PCB mounting with solder pin termination. It operates at a resonant frequency of 325 Hz and delivers a sound pressure level of 85 dBA. The unit features an impedance of 8 Ohms and a power rating of 250 mW. Physical dimensions are 23 mm in length and width, with a height of 13.5 mm. It functions within a temperature range of -30°C to +65°C.

Speakers Feature Summary

• IEC 60601-1-8 compliant design suitable for medical equipment applications
• Octagonal form factor optimized for panel or board integration
• Direct solder pin connection for secure printed circuit board attachment

Speakers Applications

• Medical diagnostic and monitoring devices requiring IEC 60601-1-8 compliance
• Industrial control panels utilizing PCB-mounted audio output
• Electronic systems requiring low-frequency acoustic signaling

Speakers Procurement Notes

Verify the specific RoHS status details provided in official documentation before procurement. Confirm that the 8 Ohm impedance and 250 mW power rating align with the target driver circuit capabilities. Ensure the PCB footprint matches the solder pin configuration and physical dimensions of 23 mm x 23 mm. Validate operating temperature requirements against the specified -30°C to +65°C range for the intended environment.

Speakers Selection Notes

Select this component when IEC 60601-1-8 certification is mandatory for the end product. Choose the MSS300R over other series if a fixed 325 Hz tone is required rather than a variable frequency buzzer. Consider the octagonal shape for space-constrained PCB layouts where circular speakers are unsuitable. Verify that the 8 Ohm load is compatible with the available amplifier output stage.

Speakers Part Context

The MSS300R belongs to the MSS series of speakers from Mallory Sonalert. This series focuses on providing reliable acoustic output for embedded applications. Unlike piezoelectric buzzers, this device is a dynamic speaker designed for lower frequency reproduction. It serves as a specialized audio component for industries requiring strict regulatory compliance in signal generation.
