AS02008MR-LWC63-R

Overview

The AS02008MR-LWC63-R is an electromagnetic speaker manufactured by PUI Audio, Inc., designed for board mount applications. It features a round shape with solder pad termination and operates within a temperature range of -20°C to +55°C. Key electrical parameters include an impedance of 8 Ohms, a power rating of 500 mW, and a sound pressure level of 86 dBA. The resonant frequency is specified at 500 Hz, with a top frequency response of 4 kHz. Physical dimensions are 20 mm in diameter and 3 mm in height, utilizing a Mylar cone and Neodymium Iron Boron magnet.

Feature Summary

• Top port design for directional audio output
• IP65 rated for dust and water resistance
• Compact low-profile form factor suitable for space-constrained PCBs

Applications

• General purpose audio signaling in electronic devices
• Portable consumer electronics requiring compact speakers
• Industrial control panels needing IP65 protection

Procurement Notes

Verify the specific suffix LWC63 against official datasheets to confirm the top port configuration and IP65 rating, as standard variants may differ. Ensure compatibility with PCB footprint requirements for solder pad termination. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated environments.

Selection Notes

Select this component when a compact, water-resistant speaker with top-firing audio output is required. The 8 Ohm impedance matches common amplifier outputs, while the 500 mW rating suits low-power applications. Consider the 3 mm height for strict vertical clearance constraints on printed circuit boards.

Part Context

This model belongs to the AS series of electromagnetic speakers from PUI Audio, Inc. It is part of a broader family of audio transducers designed for various mounting styles and environmental conditions. The specific LWC63 variant distinguishes itself through its top porting and enhanced ingress protection compared to standard open-back designs.
