W-05

Overview

The East Electronics W-05 is a through-hole piezoelectric buzzer designed for audible signaling applications. It operates at a rated voltage of 2.83 V and produces a sound pressure level of 95 dB measured at a distance of 50 cm. The device generates an acoustic frequency of 22 kHz, ensuring high-pitch alert capabilities. It utilizes PC pin termination for standard printed circuit board mounting.

Feature Summary

• Piezoelectric construction for reliable acoustic output
• Through-hole PC pin termination for secure PCB integration
• High sound pressure level generation at rated voltage

Applications

• Electronic alarm systems requiring high-pitch alerts
• Consumer electronics indicator signals
• Industrial control panel status notifications

Procurement Notes

Verify the specific operating voltage and frequency requirements against the system design before procurement. Confirm that the 2.83 V rating aligns with the available power supply rails. Ensure the 22 kHz frequency is suitable for the intended auditory application, as it exceeds typical human hearing range. Check mechanical dimensions for compatibility with the target PCB layout and enclosure constraints.

Selection Notes

Select this component when a high-decibel, high-frequency audible signal is required in a compact form factor. The through-hole package offers robust mechanical stability compared to surface-mount alternatives. Consider the 2.83 V operating point to ensure efficient drive circuitry design. Evaluate the 95 dB SPL performance against ambient noise levels to guarantee audibility in the deployment environment.
