AS01808MR-LW152-R

Overview

The AS01808MR-LW152-R is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features an 18mm external diameter and an 8-ohm impedance. The device operates within a frequency range of 650 Hz to 18 kHz with a self-resonant frequency of 450 Hz. It delivers an 80 dBA sound pressure level at 1 watt and has a nominal power rating of 1 watt, with a maximum capacity of 1.5 watts. The unit utilizes a Mylar cone and NdFeB magnet, designed for panel or board mounting via solder pads.

Feature Summary

• Top port design for directional sound output
• Compact round form factor suitable for space-constrained enclosures
• Neodymium iron boron magnetic structure for efficient performance

Applications

• Consumer electronics audio indicators
• Industrial control panel alerts
• Medical device status signaling

Procurement Notes

Verify the specific suffix configuration against official PUI Audio documentation to ensure compatibility with required acoustic parameters. Confirm that the top port orientation aligns with enclosure design constraints. Check for RoHS compliance status in the latest datasheet revision. Ensure solder pad dimensions match PCB layout specifications prior to procurement.

Selection Notes

Select this component when a compact 18mm diameter speaker is required for low-power indication tasks. The 8-ohm impedance suits standard driver circuits without complex matching networks. Consider the 80 dBA efficiency for applications requiring moderate volume levels in small enclosures. Evaluate the 1-watt power handling against peak signal requirements to prevent thermal damage during operation.

Part Context

This model belongs to the AS series of general-purpose speakers from PUI Audio, Inc., a manufacturer specializing in audio components for industrial and consumer markets. The series typically includes various diameters and power ratings to support diverse acoustic needs across appliances, security systems, and portable devices.

Replacement Considerations

Direct substitutes include other 18mm 8-ohm speakers with similar SPL ratings. Verify mechanical dimensions and terminal placement before substitution. Cross-reference impedance and frequency response curves to maintain acoustic performance integrity in existing designs.
