SOR4030S11ZN25

Overview

The SOR4030S11ZN25 is a general-purpose rectangular speaker manufactured by Seltech. It features a nominal impedance of 25 Ohms and a rated power handling capacity of 1 Watt, with a maximum power rating of 1.5 Watts. The device operates within a frequency range of 450 Hz to 15 kHz and has a resonant frequency (F0) of 450 Hz. Physical dimensions are approximately 40 mm x 30 mm x 11.5 mm. It utilizes a top port design and provides a sound pressure level of 74 dB.

Feature Summary

• Rectangular form factor with top port configuration
• General-purpose audio output capability
• Standard 25 Ohm impedance matching

Applications

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

Procurement Notes

Verify the specific impedance and power ratings against the target circuit requirements before integration. Confirm that the physical dimensions fit the designated enclosure space. Ensure the mounting method aligns with the available chassis or PCB layout options for secure installation.

Selection Notes

Select this component when a low-cost, general-purpose speaker is required for basic audio signaling. The 25 Ohm impedance suits specific amplifier outputs. Consider the limited high-frequency response above 15 kHz if music fidelity is critical. The rectangular shape allows for efficient use of linear spaces in compact devices.

Part Context

This model belongs to Seltech's line of standard rectangular speakers designed for cost-sensitive applications. It serves as a basic transducer for converting electrical signals into audible sound in non-high-fidelity environments.

Replacement Considerations

Check for direct substitutes with identical 25 Ohm impedance and similar physical footprint. Verify that alternative models support the same 1W power rating and top-port orientation to ensure mechanical compatibility.
