Active73,244 in stock

Overview

The PS1240P02BT is a miniature piezoelectric transducer designed for high-performance audio signaling in a compact form factor. It requires an external drive circuit to produce a 4kHz single-tone output and supports a wide operating voltage range up to 30V peak. Its thin profile and 5mm pin pitch make it ideal for space-constrained PCB layouts.

Why Choose This Part

This transducer offers high cost-performance in a miniature footprint of approximately 12.2mm square. It is specifically designed for compatibility with automatic radial taping machines, simplifying high-volume assembly processes. The wide 0V to 30V input range allows for flexible drive voltage selection to achieve desired sound pressure levels.

Applications

Consumer Electronics
Provides audible feedback or alert tones in handheld devices and small appliances.
Industrial Instrumentation
Integrated into control panels and measuring devices for system status notifications or error alarms.
White Goods
Used as a user-interface signal for kitchen appliances and laundry equipment.
Office Automation
Delivers audio alerts for printers, copiers, and peripheral hardware.

Getting Started

To drive this piezo transducer, implement an external square wave oscillator circuit at its resonant frequency of 4kHz. Use a standard push-pull driver or a dedicated buzzer driver IC to provide the required zero-to-peak signal. Ensure the PCB footprint accounts for the 5mm pin pitch and the circular 12.2mm diameter body.
