S110RMSS

Overview

The S110RMSS is a micro-miniature, low-profile round electromagnetic speaker manufactured by International Components Corp. It features an 8-ohm impedance and a power handling capacity of 1 watt. The device has a diameter of 28mm (1.15 inches) and a height of approximately 4.7mm to 4.8mm. Its frequency response ranges from 560 Hz to 7 kHz, with a sensitivity of 83 dB re 20.0 uPa at 1W/10cm. The construction utilizes a rare earth magnet and a Mylar diaphragm.

Feature Summary

• Micro-miniature low-profile round design suitable for space-constrained applications
• Electromagnetic transduction using a rare earth magnet and Mylar diaphragm
• Metal frame construction for structural integrity

Applications

• General purpose audio output in compact electronic devices
• Intercom systems requiring small form factor speakers
• Alarm indicators in portable equipment

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may vary. Confirm that the required impedance matches the system design, as some sources list 8 ohms while others reference different variants. Ensure the mechanical dimensions fit the enclosure constraints. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a round, low-profile speaker is required for general-purpose audio. The 8-ohm impedance is standard for many consumer electronics. Consider the 83 dB sensitivity for volume requirements in small enclosures. The 1-watt rating defines the maximum continuous power input. Verify the frequency range meets the specific audio reproduction needs of the application.

Part Context

This part belongs to the International Components Corp. speaker lineup, often distributed under the Intervox brand name. It is categorized as a micro-miniature electromagnetic transducer. The series includes various sizes and impedances, but the S110RMSS specifically denotes the 28mm diameter, 8-ohm variant with a metal frame.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. When replacing, match the 28mm diameter, 4.7mm height, and 8-ohm impedance. Ensure the replacement unit supports similar power handling and sensitivity levels to maintain acoustic performance.
