SP400804-4

Overview

The SP400804-4 is a rectangular dynamic speaker manufactured by DB Unlimited. It features a 4 Ohm impedance and a 2 W power rating. The unit measures 40 mm x 30 mm x 15 mm with lead wire termination. It delivers a sound pressure level of 100 dBA at a frequency range of 800 Hz to 10 kHz.

Feature Summary

• Rectangular shape with top port design
• Lead wire termination for direct connection
• High sound pressure level output

Applications

• Consumer electronics audio output
• Industrial control panel indicators
• Appliance status signaling

Procurement Notes

Verify the specific datasheet version for the SP400804-4 to confirm lead wire length and connector type compatibility with your assembly requirements. Ensure the operating environment stays within the specified thermal limits for the Mylar cone material. Cross-reference the 4 Ohm impedance with your amplifier output stage to prevent mismatch issues during integration.

Selection Notes

Select this component when a compact rectangular form factor is required for space-constrained enclosures. The 4 Ohm impedance suits low-voltage battery-powered applications. Consider the 100 dBA sensitivity for environments requiring clear audible alerts without high drive power. Verify that the lead wire termination method aligns with your PCB or harness design constraints.

Part Context

This model belongs to the DB Unlimited speakers and transducers category, specifically designed as a dynamic speaker. It is part of the manufacturer's lineup of audio devices intended for general-purpose sound reproduction and signaling in electronic assemblies.
