SW121108-1

Overview

The SW121108-1 is a waterproof dynamic speaker manufactured by DB Unlimited. It features a rectangular shape with dimensions of 12.00 mm in length and a maximum seated height of 2.10 mm (0.083 inches). The component operates with an impedance of 8 Ohms and has a resonant frequency of 1,100 Hz. Its specified frequency range extends from 1,100 Hz to 10,000 Hz. The sound pressure level is rated at 81 dBA when measured at a distance of 10 cm.

Feature Summary

• Waterproof construction suitable for demanding environments
• Compact rectangular form factor designed for space-constrained applications
• Top port configuration for acoustic output

Applications

• Medical devices requiring sealed audio components
• Industrial equipment needing durable transducers
• Security and surveillance systems
• Transportation audio interfaces

Procurement Notes

Verify the specific datasheet version for the SW121108-1 to confirm current manufacturing status and exact dimensional tolerances. Ensure that the 8 Ohm impedance and 81 dBA SPL ratings align with your system's power handling requirements. Confirm compatibility with your enclosure design regarding the top port orientation and overall footprint constraints before finalizing procurement.

Selection Notes

Select this model when a compact, waterproof speaker is required for high-frequency indication or communication. The 12 mm length and 2.10 mm height make it suitable for tight spaces where standard speakers cannot fit. Consider the 8 Ohm impedance for matching with existing driver circuits. The IP67 rating ensures reliability in wet or dusty conditions common in industrial or outdoor deployments.

Part Context

This component belongs to the SW series of waterproof dynamic speakers from DB Unlimited. The series includes various sizes, such as the 15 mm variant, offering scalable solutions for different acoustic needs. These speakers are part of DB Unlimited's broader portfolio of audio devices, which also includes sensors and buzzers, all focused on providing robust audio solutions for medical, industrial, and consumer markets.

Replacement Considerations

No direct public substitute part numbers are confirmed for the SW121108-1. When evaluating alternatives, ensure the replacement matches the 12x12 mm footprint, 8 Ohm impedance, and waterproof sealing requirements. Verify that the new component maintains similar frequency response characteristics within the 1.1 kHz to 10 kHz range.
