AS03808PR-R

Overview

The AS03808PR-R is a piezoelectric buzzer manufactured by PUI Audio, Inc. This component operates at a resonant frequency of 3800 Hz and produces a sound pressure level of 85 dB when driven by a 5 VDC supply. It features a through-hole mounting design with two leads for electrical connection. The device is encapsulated in a black plastic housing, providing environmental protection for the internal piezo element. These specifications define its acoustic output and electrical requirements for integration into electronic circuits.

Feature Summary

• Piezoelectric transduction mechanism for audible signal generation
• Through-hole leaded construction for standard PCB mounting
• Encapsulated housing for component protection

Applications

• Appliance status indicators
• Control panel audio alerts
• General purpose signaling devices

Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm lead form or packaging variations. Ensure the operating voltage matches the system design, as performance varies with drive voltage. Confirm mechanical dimensions fit the enclosure constraints before finalizing procurement.

Selection Notes

Select this component where a fixed frequency tone is required without active driving circuitry. Compare the 85 dB SPL requirement against ambient noise levels. Verify that the 3800 Hz frequency is appropriate for the intended alert type. Check compatibility with the target PCB layout for through-hole assembly processes.

Part Context

This part belongs to PUI Audio's line of passive piezo buzzers. Unlike active buzzers, it requires an external square wave signal to operate. The series typically offers various frequencies and sound pressure levels. The AS03808PR-R represents a specific configuration within this broader family of electromechanical signaling components.

Replacement Considerations

Substitute parts must match the 3800 Hz resonant frequency and 85 dB SPL at 5V. Verify identical pin spacing and overall dimensions for mechanical fit. Ensure the replacement component supports the same operating voltage range and mounting style.
