SP660308-1

Overview

The SP660308-1 is a dynamic speaker manufactured by DB Unlimited, designed for audio transduction applications. It features a round shape with a diameter of 28 mm and a height of 5 mm. The component operates at a resonant frequency of 380 Hz and delivers a sound pressure level of 95 dBA. It has an impedance of 8 Ohms and utilizes solder pads for termination. The unit is rated for flush mounting and functions within a standard temperature range.

Feature Summary

• Dynamic transducer technology for audio output
• Round form factor suitable for compact enclosures
• Flush mount installation style for low-profile integration
• Solder pad termination for direct PCB attachment

Applications

• Consumer electronic audio devices
• Portable communication equipment
• Industrial control panel indicators
• Medical device acoustic signaling

Procurement Notes

Verify the specific datasheet version for the SP660308-1 to confirm RoHS compliance details and exact dimensional tolerances. Ensure that the target application environment does not exceed the maximum operating temperature limits specified in the official documentation. Cross-reference the impedance and power handling capabilities with the driving circuit design to prevent damage or distortion during operation.

Selection Notes

Select this component when a low-profile, round dynamic speaker is required for flush mounting scenarios. The 8 Ohm impedance and 95 dBA sensitivity make it suitable for general-purpose audio signaling where moderate volume is sufficient. Consider the 380 Hz resonant frequency to ensure compatibility with the intended signal bandwidth requirements of the system design.

Part Context

This part belongs to the DB Unlimited speaker series, which offers various shapes including round, square, and oval configurations. The SP series typically focuses on dynamic speakers with standardized dimensions for easy integration into consumer electronics. This specific model represents a common size category used in compact audio applications requiring reliable acoustic performance.

Replacement Considerations

Check for direct substitutes from the same manufacturer series with identical mounting dimensions and electrical characteristics. Verify that any alternative component matches the 8 Ohm impedance and similar sound pressure levels to maintain system audio consistency without redesigning the enclosure or driver circuitry.
