AS03508CO-3

Overview

The AS03508CO-3 is an electromagnetic general-purpose speaker manufactured by PUI Audio, Inc. It features an 8-ohm impedance and a power rating of 1 watt, with a maximum power handling of 1.8 watts. The device operates within a frequency range of 500 Hz to 20 kHz and has a self-resonant frequency of 500 Hz. It delivers a sound pressure level of 83 dBA. The physical dimensions are 40.00 mm in length and 20.00 mm in width, with a height of 16.5 mm. The unit utilizes a cloth cone material and a neodymium magnet.

Feature Summary

Electromagnetic transducer design utilizing a neodymium magnet for efficient audio conversion
Rectangular frame construction with top port configuration for directional sound projection
Cloth cone diaphragm material selected for specific acoustic damping characteristics

Applications

General purpose audio output in embedded electronic systems
Voice prompts in consumer appliances requiring compact form factors
Alarm or notification devices in industrial control panels

Procurement Notes

Verify component status as the AS03508CO-3 is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure replacement strategies account for potential supply chain discontinuation. Validate RoHS compliance requirements against current regulatory standards before procurement integration.

Selection Notes

Select this component when a rectangular footprint fits the enclosure constraints better than circular alternatives. The 8-ohm impedance matches standard amplifier outputs. Consider the 1-watt power rating for low-volume applications. Evaluate the 500 Hz lower frequency limit to ensure suitability for voice rather than full-range music reproduction.

Part Context

This model belongs to the AS series of speakers from PUI Audio, Inc., designed for cost-effective audio solutions. The series typically offers various shapes and sizes to accommodate different housing designs. The AS03508CO-3 specifically addresses needs for rectangular mounting spaces where standard round speakers cannot fit efficiently.
