AS01808MS-SC18-WP-R

Overview

The AS01808MS-SC18-WP-R is an electromagnetic speaker transducer manufactured by PUI Audio, Inc. It features a rectangular shape with dimensions of 18 mm in length and 13 mm in width, maintaining an ultra-thin profile of approximately 2.5 to 2.8 mm in depth. The unit operates at an impedance of 8 Ohms with a power rating of 0.5 W to 1 W. It delivers a sound pressure level of 88 dBA to 96 dBA at a resonant frequency of 420 Hz to 850 Hz. The component utilizes Neodymium Iron Boron magnets and Mylar cones, offering an IP65 rating for environmental protection.

Feature Summary

• Ultra-thin rectangular design optimized for space-constrained applications
• Spring contact termination for secure board mounting
• IP65 rated enclosure for dust and water resistance
• High-fidelity audio reproduction capabilities

Applications

• Mobile devices requiring compact audio output
• Industrial control panels needing durable indicators
• Medical equipment with strict size constraints
• Consumer electronics with waterproof requirements

Procurement Notes

Verify the exact datasheet version as specifications may vary between 0.5W and 1W ratings across different sources. Confirm the spring contact orientation matches your PCB layout. Ensure the operating temperature range aligns with your specific application environment. Cross-reference the IP65 rating with your environmental exposure needs. Validate the resonant frequency against your acoustic design requirements before finalizing procurement.

Selection Notes

Select this component when a thin, rectangular form factor is critical. The spring contacts simplify assembly compared to solder pins. Consider the IP65 rating if the device faces moisture or dust. Compare the 8-ohm impedance with your amplifier output capabilities. Evaluate the 18mm x 13mm footprint against available board space. Assess the sound pressure level against audibility requirements.
