APS4209-LW178-2-R

Overview

The PUI Audio APS4209-LW178-2-R is a piezoelectric buzzer with a nominal voltage of 3.0 V and a current rating of 25 mA. It features a sound pressure level of 85 dB at 10 cm and operates within a frequency range of 2,600 Hz to 3,000 Hz. The device has a total height of 9 mm and utilizes a surface-mount package. Electrical parameters include an impedance of 16 ohms and a capacitance of 2,500 pF. It functions reliably across a temperature range of -20°C to +70°C.

Feature Summary

Surface-mount piezoelectric design for automated assembly
Integrated driver circuitry for direct logic interface
High sound pressure output relative to power consumption

Applications

Portable electronic devices requiring compact audio alerts
Consumer appliances with limited board space constraints
Industrial control panels needing reliable status indicators

Procurement Notes

Verify the specific suffix codes against manufacturer documentation to confirm exact acoustic and electrical tolerances. Ensure that the surface-mount footprint matches the PCB layout specifications provided in the official datasheet. Confirm compliance with relevant environmental standards required for the target application before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, surface-mount solution is required for audible signaling. Consider the 85 dB SPL requirement and the 3.0 V operating voltage to ensure compatibility with existing system power rails. Evaluate the 9 mm height constraint against mechanical enclosure limitations to guarantee proper fit during assembly.

Part Context

This part belongs to the PUI Audio piezoelectric buzzer family, designed for general-purpose audio indication. It differs from electromagnetic buzzers by offering higher efficiency and lower current draw. The series provides various mounting options and acoustic outputs to suit diverse electronic product designs.

Replacement Considerations

Consult the official PUI Audio cross-reference guide for verified substitute part numbers. Direct replacements must match the 3.0 V nominal voltage, 25 mA current rating, and 9 mm height specification. Verify that alternative components maintain the same surface-mount footprint and pin configuration to ensure mechanical and electrical compatibility.
