CLS0301-L152

Overview

The CLS0301-L152 is a small-size electromagnetic speaker manufactured by Same Sky. 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 (NdFeB) magnet and a Polyethylene Terephthalate (PET) cone. It offers a frequency range of 550 Hz to 13 kHz with a self-resonant frequency of 550 Hz. The sound pressure level is 89 dBA at 1W/500mm. Dimensions are 30.00 mm in diameter and 4.00 mm in height. It uses wire leads for termination and has a top port location.

Feature Summary

• Top-port acoustic design for direct sound projection
• Compact circular form factor utilizing PET cone material
• High-efficiency magnetic structure using NdFeB components

Applications

• Portable electronic devices requiring compact audio output
• Medical equipment needing reliable miniature speakers
• Consumer electronics with limited internal volume

Procurement Notes

Verify the specific suffix L152 indicates wire lead termination distinct from other variants. Confirm RoHS3 compliance status through official documentation before integration. Ensure enclosure design accommodates the 4.00 mm maximum height and 30.00 mm diameter constraints. Validate thermal management requirements against the 200 mW rated power specification.

Selection Notes

Select this model when top-port sound directionality is required within a 30 mm footprint. Compare sensitivity and frequency response against alternatives if wide-bandwidth performance is critical. Consider the wire lead termination method for assembly compatibility versus solder pin options available in the series.

Part Context

This component belongs to the CLS series of miniature speakers from Same Sky. The series provides various configurations differing in size, power rating, and termination style. The CLS0301 base model represents a standard 30 mm diameter option within this product line.
