SW280708-1

Overview

The SW280708-1 is a dynamic electromagnetic speaker manufactured by DB Unlimited. It features an 8-ohm impedance and a rated power of 1.5W. The unit has a diameter of 28mm and operates within a frequency range of 700Hz to 10kHz, with a resonance frequency at 700Hz. It delivers a sound pressure level of 92dBA. The speaker utilizes a top port design and employs solder pad termination for electrical connection.

Feature Summary

• Waterproof construction with IP67 rating for dust and splash resistance
• Compact round form factor suitable for embedded installation
• Top port acoustic design

Applications

• Embedded audio devices requiring waterproof components
• Industrial equipment exposed to dust or moisture
• Portable electronic devices with limited space

Procurement Notes

Verify the specific IP67 rating and dimensional tolerances against your enclosure design requirements. Confirm that the 1.5W power handling aligns with your amplifier output capabilities. Ensure the solder pad termination method matches your PCB assembly process. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a small, waterproof speaker is needed for harsh environments. The 28mm diameter fits tight spaces where larger speakers cannot be used. The 8-ohm impedance is standard for many audio circuits. Consider the 92dBA efficiency for applications requiring moderate volume levels without excessive power consumption.

Part Context

DB Unlimited specializes in compact, high-performance audio transducers. The SW series includes various sizes and ratings. This model is part of their waterproof line, designed for durability. Similar models may vary in size, power, or IP rating. Always consult the official datasheet for precise mechanical and electrical specifications before integration.

Replacement Considerations

Direct substitutes must match the 28mm diameter, 8-ohm impedance, and IP67 rating. Models like SW280408-2 share similar dimensions but may differ in power handling or frequency response. Verify acoustic performance and mounting compatibility before substitution.
