PS1720P02

Overview

The TDK PS1720P02 is a piezoelectric buzzer designed for printed circuit board mounting. It operates with an external drive and features a rated input voltage of 3V (peak-to-peak). The device produces a minimum sound pressure level of 70dB at its resonant frequency of 2kHz. Physically, it has a diameter of 17mm and a height of 8mm. The component utilizes pin terminals for through-hole installation and functions within a temperature range of -10°C to 70°C.

Feature Summary

• Utilizes a single crystal piezoelectric element for low power consumption
• Designed for easy integration into various circuits via pin terminals
• Provides audible indication with high performance characteristics

Applications

• General purpose electronic equipment
• Alarm systems
• Audio indicators

Procurement Notes

Verify the specific datasheet version for the PS1720P02 to confirm electrical tolerances and mechanical dimensions. Ensure compatibility with the target operating temperature range of -10°C to 70°C. Confirm that the external drive circuit can supply the required peak-to-peak voltage without exceeding maximum ratings. Check for RoHS compliance requirements if applicable to the final assembly.

Selection Notes

Select this component when a low-profile, externally driven piezoelectric buzzer is required. The 17mm diameter and 8mm height suit space-constrained PCB layouts. Consider the 3V rating against available supply voltages. The 2kHz frequency provides a distinct audible tone suitable for alerts. Verify that the application does not require an internal oscillator, as this model requires external driving signals.

Part Context

This part belongs to the TDK PS series of piezoelectric buzzers. The series is characterized by the use of single crystal piezoelectric elements, offering high performance and low power consumption. These components are typically used in applications requiring reliable audio signaling with minimal energy usage.

Replacement Considerations

Direct substitutes must match the 17mm diameter, 8mm height, 3V rated voltage, and 2kHz frequency. Verify terminal pitch and package type compatibility. Consult official TDK documentation for approved alternative part numbers within the PS series or equivalent specifications from other manufacturers.
