CLS0201MP

Overview

The CLS0201MP is an electromagnetic speaker manufactured by Same Sky, featuring a round frame with a 20 mm diameter and 4.2 mm depth. It operates at an impedance of 8 Ohms with a rated power of 100 mW and a maximum power handling of 200 mW. The unit utilizes a Neodymium Iron Boron magnet and a Polyethylene Terephthalate cone. Key acoustic parameters include a resonant frequency of 850 Hz, a frequency range of 680 Hz to 7 kHz, and a sound pressure level of 78 dBA. It employs PCB mount solder pin termination and functions within a temperature range of -25°C to +60°C.

Feature Summary

• Utilizes a neodymium iron boron magnetic structure for efficient audio transduction.
• Features a polyethylene terephthalate cone material for durability.
• Designed for direct printed circuit board mounting via solder pins.

Applications

• General purpose audio output devices
• Medical application electronics
• Micro speaker systems

Procurement Notes

Verify the specific suffix 'MP' to confirm the inclusion of PCB pins and PET cone construction, as standard variants may differ in termination or materials. Ensure the design accommodates the 20 mm diameter and 4.2 mm height constraints. Confirm RoHS3 compliance requirements align with the component's environmental certification before finalizing procurement specifications.

Selection Notes

Select this model when a compact 20 mm form factor with low power consumption is required. The 8 Ohm impedance suits standard low-voltage driver circuits. Consider the 78 dBA sensitivity for applications not requiring high-volume output without amplification. Verify that the 100 mW rating meets the continuous power demands of the target system.

Part Context

This component belongs to the CLS series of miniature speakers from Same Sky. The series offers various sizes and power ratings, utilizing both paper and PET cones with different magnetic materials. The CLS0201MP specifically targets general-purpose applications requiring a balance of size and acoustic performance.

Replacement Considerations

CLS0201MA serves as a similar alternative within the same series but features a 500 mW rating and pad termination instead of pins. CLS0201 is another variant with a paper cone. Verify dimensional compatibility and electrical characteristics before substituting.
