OWS-142550TA-4

Speakers Overview

The OWS-142550TA-4 is a rectangular IoT speaker manufactured by Ole Wolff Electronics Inc. It features a 4 Ohm impedance and a rated power of 2 W. The device operates within a frequency range of 800 Hz to 12 kHz. Its physical dimensions are 25.0 mm in length, 14.0 mm in width, and 5.0 mm in height. The unit utilizes a top port design for sound output.

Speakers Feature Summary

• Rectangular form factor optimized for cavity integration
• Top port acoustic design
• Magnetic technology construction

Speakers Applications

• IoT devices
• Model train sound installations (ESU LokSound)
• Compact electronic enclosures

Speakers Procurement Notes

Verify the specific datasheet version when ordering, as supplier listings may present conflicting sensitivity values such as 80 dB or 103 dB. Confirm that the 4 Ohm impedance matches the target circuit requirements. Ensure the top port orientation aligns with the mechanical layout constraints of the final assembly.

Speakers Selection Notes

Select this component for applications requiring a small footprint with a 2 W power handling capacity. The 4 Ohm impedance suits standard low-voltage audio drivers. Consider the 800 Hz to 12 kHz frequency response limitations for voice-centric or limited-bandwidth audio needs rather than full-range music reproduction.

Speakers Part Context

This model belongs to the OWS series of micro speakers from Ole Wolff Electronics Inc. These components are engineered for high output in small cavities around 1cc volume. The series includes various impedance and dimension variants tailored for embedded electronics and specialized audio modules.
