PS1920P02

Overview

The PS1920P02 is a piezoelectric buzzer from the PS series manufactured by TDK Corporation. It features pin terminals and operates at a rated input voltage of 5V peak-to-peak. The device generates a minimum sound pressure level of 70dB at a frequency of 2kHz. Its physical dimensions are 19.00mm nominal outer diameter and 11.00mm nominal height. The component supports fluid soldering methods and functions within an operating temperature range of -10°C to 70°C.

Feature Summary

• Generates audible alerts using piezoelectric technology
• Designed for through-hole mounting via pin terminals
• Operates on standard 5V peak-to-peak input signals

Applications

• General purpose electronic equipment indicators
• Appliance status signaling
• Control panel audio feedback

Procurement Notes

Verify that the specific order matches the PS1920P02 designation, as suffixes may indicate variations in terminal configuration or acoustic performance. Confirm compliance with RoHS and REACH requirements relevant to the target market. Ensure the procurement documentation references the official TDK datasheet for accurate thermal and mechanical handling specifications during assembly.

Selection Notes

Select this component when a compact, low-voltage audible indicator is required for general-grade applications. The 19mm diameter offers a balance between acoustic output and board space constraints. Consider the 2kHz frequency response for optimal human hearing sensitivity in noisy environments. Verify that the 5V peak-to-peak drive capability aligns with the host circuit's output stage.

Part Context

This part belongs to the PS series of piezoelectric buzzers produced by TDK Corporation. The series provides various sizes and acoustic outputs for different enclosure constraints. The PS1920P02 specifically addresses needs for moderate sound pressure levels in consumer and industrial devices where reliability and simple driving circuits are prioritized over complex tone generation.

Replacement Considerations

Consult the official TDK catalog for direct replacements within the PS series. Verify dimensional compatibility, particularly the 19mm outer diameter and 11mm height. Ensure the replacement maintains the 5V peak-to-peak rating and 2kHz frequency characteristic to preserve acoustic performance.
