Overview
The CLS0301MA-L152 is a miniature top-ported speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 200 mW, with a maximum power handling capacity of 400 mW. The device delivers an efficiency of 89 dBA at 1W/500mm. Its frequency response spans from 550 Hz to 13 kHz, with a self-resonant frequency of 550 Hz. The circular unit measures 30.00 mm in diameter and has a maximum installation height of 4.00 mm. Termination is achieved via wire leads.
Feature Summary
- Top-ported acoustic design for direct sound projection
- Compact circular form factor suitable for space-constrained enclosures
- High sensitivity output relative to input power
- Utilizes Neodymium Iron Boron magnetic material
Applications
- Portable electronic devices requiring small audio output
- Medical equipment with limited internal volume
- Consumer electronics and smart home gadgets
- Industrial control panels needing audible feedback
Procurement Notes
Verify the specific suffix L152 to confirm wire lead termination type, as other variants may use solder pads or PC pins. Ensure the receiving environment supports the operating temperature range specified in the official datasheet. Confirm RoHS3 compliance requirements align with project regulations before finalizing the order.
Selection Notes
Select this model when a top-ported configuration is required for optimal acoustic performance in sealed or semi-sealed housings. Compare the 200 mW rating against peak signal demands to ensure reliability. Consider the 4.00 mm height constraint against available vertical clearance in the target assembly.
Part Context
This component belongs to the CLS series of miniature speakers from Same Sky (Formerly CUI Devices). The series offers various sizes and mounting options. The CLS0301MA-L152 specifically utilizes a PET diaphragm and Nd-Fe-B magnet, distinguishing it from paper cone or different termination variants within the broader product line.
Replacement Considerations
Direct substitutes include CLS0301MP-1 and CLS0261MAE-L152, though these differ in power ratings, frequency ranges, and physical dimensions. Verify that alternative part numbers match the required impedance and mounting style before integration.
