SP-4012-8Y

Overview

The SP-4012-8Y is a general-purpose rectangular speaker manufactured by Soberton Inc. It features an 8 Ohms impedance and a power rating of 2 W to 3 W. The frequency range spans from 400 Hz to 12 kHz with a sensitivity of 78 dBA. The unit has a top port location, square shape, and solder eyelet terminals. Maximum seated height is 0.465 inches (11.80 mm).

Feature Summary

Rectangular design with top port location for versatile mounting.
Solder eyelet terminals for direct circuit board integration.
RoHS compliant construction.

Applications

General purpose audio output in consumer electronics.
Indicators and alarms in household appliances.
Portable electronic devices requiring compact speakers.

Procurement Notes

Verify the specific datasheet version for exact mechanical dimensions and electrical tolerances before finalizing designs. Confirm RoHS compliance status if required by your manufacturing standards. Ensure terminal compatibility with your assembly process, as this model uses solder eyelets. Cross-reference part numbers carefully to distinguish between similar Soberton series variants.

Selection Notes

Select this component when a low-profile, rectangular form factor is required for space-constrained enclosures. The 8 Ohm impedance suits standard amplifier outputs. Consider the 400 Hz lower frequency limit; it is not suitable for full-range audio reproduction requiring deep bass response. Verify that the 78 dBA sensitivity meets the volume requirements of the target application environment.

Part Context

This speaker belongs to Soberton's general-purpose line, characterized by magnetic technology and robust construction for everyday use. It is distinct from high-fidelity or waterproof models, focusing on cost-effective performance for basic audio signaling tasks.

Replacement Considerations

Check for identical impedance (8 Ohms) and physical dimensions to ensure fit. Sensitivity variations may affect volume levels. Terminal type must match existing PCB layouts.
