SM450204-1

Overview

The SM450204-1 is a rectangular dynamic speaker manufactured by DB Unlimited. It features a 4 Ohm impedance and a power rating of 3 W. The unit operates within a frequency range of 200 Hz to 10 kHz, delivering an 88 dBA sound pressure level. Physical dimensions are 45 mm in length, 36 mm in width, and 19.5 mm in depth. It utilizes lead wire termination and employs Mylar for the cone material.

Feature Summary

• Rectangular form factor with flange mount capability
• Lead wire termination for direct circuit connection
• Mylar cone construction for acoustic performance

Applications

• General purpose audio output devices
• Embedded electronic enclosures requiring compact speakers
• Industrial control panels with limited space

Procurement Notes

Verify the specific impedance and power rating against your design requirements before procurement. Confirm that the lead wire termination style matches your assembly process. Ensure the physical dimensions fit within the designated enclosure space. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this model when a rectangular shape is necessary for panel integration. The 4 Ohm impedance suits standard low-voltage audio drivers. Consider the 19.5 mm depth constraint during mechanical design. The lead wire option simplifies wiring compared to solder pad alternatives.

Part Context

This component belongs to the general-purpose speaker category from DB Unlimited. It shares the rectangular series characteristics with similar models like the SM450208-2, differing primarily in impedance and connector type. The product line focuses on compact transducers for embedded applications.

Replacement Considerations

The SM450208-2 serves as a functional substitute with identical dimensions but differs in 8 Ohm impedance and wire lead configuration. Verify electrical compatibility when swapping between these variants.
