PT-2725FPLQ

Overview

The PT-2725FPLQ is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates at a frequency of 2.5 kHz with a sound pressure level of unspecified dB. The device features a dual-tone output and utilizes a self-drive mechanism. Electrical specifications include a rated voltage of 12 V and a current rating of 10 mA. The component employs solder pin termination for through-hole mounting. Physical dimensions are 30 mm in diameter and 6 mm in height.

Feature Summary

• Dual-tone acoustic output capability
• Self-drive piezoelectric transducer design
• Through-hole solder pin termination

Applications

• Industrial equipment status indication
• Consumer appliance audio signaling
• Transportation system alerts

Procurement Notes

Verify the specific datasheet version to confirm exact sound pressure levels, as public listings may omit precise decibel metrics. Ensure compatibility with 12 V DC supply requirements. Confirm that the 6 mm terminal spacing matches the target PCB layout. Check RoHS compliance documentation for regulatory adherence in restricted regions.

Selection Notes

Select this model when a compact, low-profile buzzer is required for board-mounted applications. The 30 mm diameter fits standard panel cutouts or tight PCB spaces. The self-drive feature simplifies circuit design by eliminating external oscillator components. Verify thermal tolerance against operating environment constraints.

Part Context

This component belongs to the PT series of piezoelectric buzzers from Mallory Sonalert. The series is characterized by robust construction and reliable acoustic performance for general-purpose signaling. The PT-2725FPLQ variant specifically targets 12 V systems with a 2.5 kHz fundamental frequency.

Replacement Considerations

Cross-reference with PT-2735FPQ for similar form factor but different frequency. Verify electrical parameters against PT-2725FPLQ equivalents from other manufacturers if supply chain issues arise.
