CLS0381M-L152

Overview

The CLS0381M-L152 is a miniature speaker manufactured by Same Sky (Formerly CUI Devices). It features an 8-ohm impedance and a rated power of 200 mW, with a maximum power handling of 400 mW. The device utilizes a Neodymium Iron Boron magnet and a Polyethylene Terephthalate (PET) diaphragm. Its frequency response ranges from 6 inches lead wires to 9 kHz, with a self-resonant frequency of 800 Hz. The unit has a circular shape with a diameter of 38.00 mm and a maximum installation height of 17.00 mm. Sensitivity is specified at 79 dBA, tested at 200 mW/500mm. Termination is provided via solder lug eyes.

Feature Summary

• Compact circular design suitable for space-constrained audio applications
• Top port configuration for directed sound output
• Utilizes Nd-Fe-B magnetic technology for efficient performance
• Equipped with PET diaphragm material for durability

Applications

• Medical electronic devices requiring compact audio components
• General purpose audio signal indication
• Portable consumer electronics with limited internal volume

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct termination style and lead length specifications. Confirm RoHS3 compliance status through current certificates of conformity. Check for any recent lifecycle changes or obsolescence notices directly from the supplier before finalizing procurement plans.

Selection Notes

Select this component when a low-profile, top-port speaker is required for general audio tasks. Ensure the application environment accommodates the 17.00 mm height constraint. Verify that the 8-ohm impedance matches the driving circuit requirements. Consider the 200 mW rated power limit for continuous operation scenarios to prevent thermal damage.
