AS07104PO-LW152-R

Overview

The AS07104PO-LW152-R is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features a 4-ohm nominal impedance and a 3-watt power rating. The device operates within a frequency range of 100 Hz to 20 kHz, with a self-resonant frequency of 250 Hz. It delivers an 86 dBA sound pressure level at 1 watt/10 cm. The physical dimensions are 71 mm in length, 41 mm in width, and 25 mm in height. It utilizes a neodymium iron boron magnet and a paper cone, terminating via solder lugs for frame mounting.

Feature Summary

• Electromagnetic transducer design utilizing neodymium iron boron magnets
• Oval rectangular form factor optimized for frame mounting applications
• Paper cone construction for acoustic performance
• Solder lug termination for direct circuit integration

Applications

• General purpose audio output devices
• Industrial control panel indicators
• Consumer electronics enclosures
• Appliance status signaling

Procurement Notes

Verify the specific suffix LW152 against official PUI Audio documentation to confirm exact acoustic tolerances and material specifications. Ensure the 4-ohm impedance matches the driving circuit requirements. Confirm that the 3-watt power rating aligns with the intended operational duty cycle. Validate that the 71x41 mm physical footprint fits the designated enclosure space. Check for RoHS compliance status if required by the target market regulations.

Selection Notes

Select this component when a compact oval speaker is required for frame-mounted installations. The 4-ohm impedance suits standard low-voltage audio drivers. The 86 dBA sensitivity provides adequate volume for proximity listening. Consider the 100 Hz lower frequency limit when bass response is not critical. The paper cone offers a cost-effective solution for general announcements or simple tone generation.

Part Context

This model belongs to the AS series of speakers from PUI Audio, Inc., which focuses on electromagnetic transducers for industrial and consumer markets. The AS series typically offers various shapes and impedances to accommodate diverse enclosure constraints. This specific part represents a standard oval configuration designed for easy integration into existing chassis designs without complex mounting hardware.

Replacement Considerations

Direct substitutes must match the 4-ohm impedance, 3-watt rating, and 71x41 mm dimensions. Verify that alternative models maintain the 86 dBA SPL and 100-20 kHz frequency response. Ensure the replacement supports solder lug termination and frame mounting. Cross-reference with PUI Audio's current AS series catalog for updated equivalents.
