SP-1303L-3

Overview

The SP-1303L-3 is a general purpose dynamic speaker unit manufactured by Soberton Inc. It features an 8-ohm impedance and a rated input power of 500 mW, with a maximum handling capacity of 0.8 W. The device delivers a sound pressure level of 87 dBA when tested at 100 mW/100 mm. Its frequency response spans from 300 Hz to 8 kHz, with a resonant frequency of approximately 1100 Hz. The speaker utilizes a round shape with a top port location and terminates via eyelets.

Feature Summary

• Round dynamic speaker design with top port location
• Eyelet termination for wire lead connection
• General purpose audio reproduction capability

Applications

• Consumer electronics audio output
• Industrial control panel indicators
• General purpose alarm systems

Procurement Notes

Verify the specific suffix designation (e.g., -3) against the official Soberton Inc. datasheet to confirm impedance, power rating, and termination type match project requirements. Ensure environmental conditions align with the component's operational limits. Confirm RoHS compliance status if required by regulatory standards before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a compact, round-form factor speaker with standard 8-ohm impedance. The eyelet termination facilitates easy integration into circuits using wire leads. Consider the 300 Hz to 8 kHz frequency range suitability for voice or alert tones rather than high-fidelity music reproduction.

Part Context

This model belongs to the SP series of dynamic speaker units from Soberton Inc. The series includes variants such as SP-1303L-1 and SP-1303L-2, which share similar physical dimensions and acoustic principles but may differ in specific electrical parameters or termination styles. The SP-1303L-3 specifically denotes the configuration with eyelet terminations.

Replacement Considerations

Direct substitutes include other Soberton SP-1303L variants like the SP-1303L-1 or SP-1303L-2, provided the termination style matches the PCB or wiring harness design. Cross-brand replacements must match the 8-ohm impedance, 500 mW power rating, and physical mounting constraints.
