AS04008PO-2-LW152-R

Overview

The AS04008PO-2-LW152-R is an 8-ohm, 3-watt piezo buzzer from PUI Audio. It features a low-profile design with a total height of approximately 8.0 mm and a diameter of 40.0 mm. The device operates within a frequency range centered around 2.7 kHz to 3.0 kHz, producing a sound pressure level of at least 85 dB at 10 cm. It utilizes a polarized construction requiring correct polarity for operation and is designed for through-hole mounting via two radial leads.

Feature Summary

• Compact low-profile form factor suitable for space-constrained enclosures
• Piezoelectric technology providing reliable acoustic output without moving parts
• Polarized design ensuring consistent performance with specified voltage input

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required acoustic and electrical specifications. Confirm lead times and availability directly with authorized distributors as supply chain conditions may vary. Ensure proper handling procedures are followed during installation to prevent damage to the piezoelectric element.

Selection Notes

Select this component when a compact, high-output audible indicator is required. Consider the operating voltage and frequency response to match the driving circuit capabilities. Evaluate the mechanical constraints of the enclosure to ensure the 8.0 mm height and 40.0 mm diameter fit within the designated space while maintaining adequate acoustic coupling.

Part Context

This model belongs to PUI Audio's series of piezoelectric buzzers designed for general-purpose audible signaling. The product line emphasizes reliability and cost-effectiveness for mass-produced electronic devices. The specific model variant indicates standard acoustic characteristics and mounting configuration typical of their commercial-grade offerings.

Replacement Considerations

Consult official substitution guides for equivalent acoustic output and mechanical dimensions. Verify that any alternative part matches the 8-ohm impedance and 3-watt power rating to ensure circuit compatibility. Confirm that the replacement maintains the same polarization requirements and mounting style.
