Overview

The PKM13EPYH4000-A0 is a compact, externally driven piezoelectric sounder designed for low power consumption and high reliability. Operating at a resonant frequency of 4kHz, it produces a 70dB sound pressure level while drawing a maximum of 25mA, making it suitable for compact electronic signaling.

Why Choose This Part

This transducer offers a wide operating voltage range up to 30V peak, providing design flexibility for various drive circuits. Its piezo technology ensures minimal electromagnetic interference and low power consumption compared to electromagnetic buzzers.

Applications

Consumer Electronic Alarms
Ideal for providing audible feedback or error alerts in household appliances and small electronics.
Industrial Signaling
Used in control panels and handheld instruments where a clear 4kHz tone is required for status indication.
Battery-Powered Devices
Optimized for efficiency in portable equipment, operating effectively at a rated voltage of 1.5V.
