CLS0402MA-1

Overview

The CLS0402MA-1 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 of 1 W. The device operates within a frequency range of 530 Hz to 6 kHz and has a self-resonant frequency of 530 Hz. It delivers a sound pressure level of 92 dB when tested at 1 W/10 cm. The speaker utilizes a Neodymium magnet and a PET cone, with top porting and wire lead termination. Its physical dimensions are 40 mm in diameter and 5.3 mm in height.

Feature Summary

• Utilizes a neodymium magnet for efficient magnetic field generation in a compact form factor.
• Features a polyester cone designed for durability and consistent acoustic performance.
• Incorporates top porting to direct sound output effectively from the upper surface.
• Equipped with wire leads for straightforward electrical connection during assembly.

Applications

• Consumer electronic devices requiring compact audio output
• Medical equipment needing reliable miniature speakers
• Industrial control panels with limited space constraints

Procurement Notes

Verify the specific suffix requirements against your design needs, as variations may exist within the CLS series. Confirm that the wire lead termination style matches your PCB or harness interface. Ensure the operating environment remains within the specified temperature and humidity ranges to maintain performance integrity and longevity of the components.

Selection Notes

Select this model when an 8 Ohm impedance and 500 mW rating align with the amplifier capabilities. The 40 mm diameter fits standard enclosure cutouts for medium-sized audio applications. Consider the top-porting design if rear clearance is restricted. Verify that the 530 Hz to 6 kHz frequency response covers the required audio bandwidth for the intended application.

Part Context

This component belongs to the CLS series of miniature speakers from Same Sky. The series offers various sizes and impedances tailored for different audio requirements. The CLS0402MA-1 specifically addresses needs for moderate power handling and broad availability in consumer and industrial sectors. It represents a standard solution for general-purpose audio reproduction in small enclosures.

Replacement Considerations

CLS0402MA-1-L152 is a documented variant within the same product line. Verify compatibility regarding lead length and terminal configuration before substitution. Other models in the CLS series may share similar mounting dimensions but differ in electrical parameters.
