AI-2437-TWT-2-R

Overview

The AI-2437-TWT-2-R is a piezoelectric buzzer manufactured by PUI Audio, Inc. It features a 24 mm diameter and operates at a resonant frequency of 3.7 kHz. The device is rated for 12 VDC with an internal driving circuit, classifying it as an active buzzer. It produces a sound pressure level of 100 dBA and draws 8 mA of current. Designed for through-hole mounting, this component serves as a continuous audio indicator.

Feature Summary

• Built-in driving circuitry enables direct connection to voltage sources without external oscillators.
• Piezoelectric transducer technology provides high acoustic output efficiency.
• Through-hole termination supports standard PCB assembly processes.

Applications

• Industrial control panel status indicators
• Appliance operational alerts
• Electronic equipment alarm systems

Procurement Notes

Verify the specific suffix '2' in the part number to confirm the 12VDC rating and 8mA current draw. Ensure the through-hole package style matches the target PCB footprint. Confirm RoHS compliance requirements against project specifications before finalizing procurement orders.

Selection Notes

Select this component when a high-decibel audible alert is required from a compact 24 mm form factor. The integrated driver simplifies schematic design by removing the need for external transistor or oscillator circuits. Consider the 12VDC operating voltage to ensure compatibility with existing power rails.

Part Context

This model belongs to PUI Audio's piezoelectric buzzer series, which emphasizes reliability and consistent acoustic performance. The AI prefix typically denotes active buzzer variants within the manufacturer's catalog, distinguishing them from passive transducers that require external signal generation.
