SM150508-7

Overview

The SM150508-7 is a dynamic micro speaker from the DB Unlimited Power Micro series, designed for space-constrained IoT and handheld devices. It features a rectangular Mylar cone with spring contacts for flush mounting. Key electrical parameters include an 8 Ohm impedance, 750 mW power rating, and 92 dBA sound pressure level. The unit operates within a -40°C to +85°C temperature range and measures 15 mm x 8 mm x 3.9 mm.

Feature Summary

• High-performance size-to-output ratio optimized for compact enclosures
• Spring contact termination method facilitates automated manufacturing assembly
• Wide frequency spectrum capability suitable for voice applications

Applications

• IoT voice modules
• Handheld electronic devices
• Compact audio transducers

Procurement Notes

Verify the specific RoHS compliance status through official documentation before integration. Confirm that the spring contact termination aligns with your PCB design requirements. Ensure the operating temperature range meets your environmental specifications. Check for any recent lifecycle changes or obsolescence notices directly from the manufacturer.

Selection Notes

Select this component when strict spatial limitations require a miniature form factor without sacrificing acoustic output. The spring contact interface offers a distinct advantage over soldered terminals for high-volume production lines. Consider the 8 Ohm impedance match against your amplifier's output capabilities to ensure optimal power transfer and efficiency.

Part Context

This model belongs to the SM series of Power Micro speakers, which are engineered to deliver full-range audio in minimal footprints. The series utilizes advanced materials to achieve industry-leading power handling relative to physical dimensions, addressing the growing demand for integrated audio in small consumer electronics.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same series. Verify that any substitute maintains identical mechanical dimensions and electrical characteristics to avoid redesigning the enclosure or circuitry.
