CLF0381MP-1

Overview

The CLF0381MP-1 is a miniature round loudspeaker manufactured by Same Sky (Formerly CUI Devices). It features an 8 Ohm impedance and a rated power of 250 mW, with a maximum power handling capacity of 400 mW. The device utilizes a ferrite magnet and a PET cone for sound reproduction. Its frequency range spans from 380 Hz to 10 kHz, with a self-resonant frequency at 380 Hz. The speaker delivers a sound pressure level of 93 dBA when tested at 250 mW/10cm. Physical dimensions include a 38 mm diameter frame and a maximum installation height of 9.4 mm. It employs solder pin terminals for electrical connection.

Feature Summary

• Compact round design suitable for space-constrained applications
• Utilizes ferrite magnet technology for efficient audio output
• Features PET cone construction for durability
• Supports top port configuration for direct sound projection

Applications

• General purpose audio signaling
• Miniature electronic devices
• Industrial control panels
• Consumer electronics enclosures

Procurement Notes

Verify the specific magnet type and sensitivity specifications against the official manufacturer datasheet prior to procurement. Ensure that the solder pin terminal style matches the target PCB layout requirements. Confirm compliance with RoHS3 regulations if environmental standards are mandatory for the project. Cross-reference the maximum power rating with the intended operating conditions to prevent thermal damage during high-load scenarios.

Selection Notes

Select this component when a low-profile, round form factor is required for audio indication. The 8 Ohm impedance aligns with standard driver circuits. Consider the 93 dBA sensitivity for applications requiring moderate volume levels without additional amplification. The 38 mm diameter allows for integration into various housing designs while maintaining a minimal footprint relative to larger speakers.

Part Context

This model belongs to the Same Sky miniature speaker lineup, designed for compact audio solutions. It serves as a general-purpose transducer for indicating status or providing simple audio feedback in electronic assemblies. The product is distinct from higher-power or wider-frequency-range models within the same manufacturer's catalog, focusing on cost-effective performance for standard signaling tasks.

Replacement Considerations

Direct substitutes may include other 38mm round speakers with similar 8 Ohm impedance and comparable sensitivity ratings. Verify mechanical mounting hole patterns and terminal types to ensure compatibility. Check frequency response curves to confirm adequate performance for the specific application bandwidth requirements.
