CLS0402MA-1-L152

Overview

The CLS0402MA-1-L152 is a miniature round speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 500 mW, with a maximum power handling capacity of 1 W. The device operates within a frequency range of 530 Hz to 6 kHz and exhibits a self-resonant frequency of 530 Hz. Acoustic performance includes a sound pressure level (SPL) of 89 dBA, measured at 1 W/10cm. The unit utilizes a top port configuration and employs a PET diaphragm with an Nd-Fe-B magnet. Physical dimensions are 1.181 inches in diameter and 0.157 inches in maximum height.

Feature Summary

• Utilizes a neodymium iron boron magnetic structure for high efficiency in a compact form factor.
• Features a polyester diaphragm designed for durability and consistent acoustic response.
• Offers top-porting capability to facilitate direct sound projection in constrained enclosures.

Applications

• Portable consumer electronics requiring small form factor audio output
• Medical devices needing reliable miniature sound components
• Industrial control panels with limited internal space

Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm exact electrical tolerances and mechanical drawings. Ensure compatibility with existing enclosure designs regarding the top-port orientation and mounting height constraints. Cross-reference the official datasheet for RoHS compliance status and recommended soldering profiles to maintain component integrity during assembly.

Selection Notes

Select this model when an 8 Ohm impedance matches the amplifier output requirements. Consider the 500 mW rating against expected operational volume levels to prevent thermal damage. Evaluate the 530 Hz to 6 kHz frequency range suitability for the intended voice or alert signals. Confirm that the 1.181-inch diameter fits within the available chassis space.

Part Context

This component belongs to the CLS series of miniature speakers from Same Sky. The series focuses on providing high-performance audio solutions in small packages suitable for modern electronic devices. The CLS0402 variant specifically addresses applications requiring robust sound output from very limited physical footprints.

Replacement Considerations

Consult the manufacturer's cross-reference list for verified substitutes. Ensure any replacement maintains the 8 Ohm impedance and similar SPL characteristics to avoid circuit redesign.
