SP-4008Y

Overview

The SP-4008Y is a general-purpose round speaker manufactured by Soberton Inc. It features a 40mm diameter diaphragm and a nominal impedance of 4 Ohms. The component supports an input power rating of 2.5W and delivers a sound pressure level of 90dB. Its frequency range spans from 550Hz to 10kHz, with a self-resonant frequency of 550Hz. The device utilizes eyelet termination for electrical connection.

Feature Summary

• Round shape design with 40mm diameter
• Eyelet termination style
• General purpose audio application

Applications

• Consumer electronics audio output
• Small enclosure sound reproduction
• General purpose acoustic signaling

Procurement Notes

Verify the specific datasheet version provided by Soberton Inc. or authorized distributors to confirm exact mechanical dimensions and tolerance specifications. Ensure that the eyelet termination type matches the intended wiring method for the target assembly. Cross-reference the impedance and power ratings against the amplifier output capabilities to prevent thermal damage during operation.

Selection Notes

Select this component when a compact 40mm round speaker is required for low-to-moderate volume applications. The 4 Ohm impedance suits standard low-voltage audio circuits. Consider the 550Hz lower frequency limit; it may not be suitable for deep bass reproduction. Verify that the physical space allows for the specified diameter and height constraints.

Part Context

This part belongs to Soberton Inc.'s line of electromagnetic transducers and sound devices. The manufacturer specializes in magnetic transducers, piezo buzzers, and electret condenser microphones. The SP-4008Y represents their standard general-purpose speaker offering within this product family.

Replacement Considerations

Direct substitutes include other 4 Ohm, 40mm round speakers with similar power handling and frequency response. Check compatibility of eyelet terminals versus solder tabs if alternative mounting is required.
