Overview
The TDK PS1740P02CE is a piezoelectric buzzer designed for through-hole mounting. It operates at a rated voltage of 3 V and produces a continuous tone at a frequency of 4 kHz. The device delivers a sound pressure level of 60 dBA. Its physical dimensions are 17 mm in diameter and 4.6 mm in height, utilizing solder pin terminals for board integration.
Feature Summary
- Externally driven piezoelectric transducer without an internal oscillator circuit
- Through-hole installation with solder pin terminals
- Continuous tone generation capability
Applications
- Public information-processing equipment
- Military equipment
- General audio indicators and alerts
Procurement Notes
Verify the specific suffix 'CE' against the manufacturer's current datasheet to confirm terminal configuration and environmental compliance status. Ensure the design accommodates the 17 mm diameter and 4.6 mm height constraints for the target PCB layout. Confirm that the external drive circuit can supply the necessary current for the 3 V rated input to achieve the specified acoustic output levels.
Selection Notes
Select this component when a low-profile, externally driven piezoelectric indicator is required for through-hole assembly. It is suitable for applications needing a fixed 4 kHz tone at 3 V operation. Consider the 60 dBA output level relative to the enclosure acoustics. This part lacks an internal oscillator, requiring an external signal source for activation.
Part Context
This component belongs to the TDK PS series of piezoelectric buzzers. The series offers various sizes and frequencies for board-mount audio indication. The PS1740P02CE specifically represents the 17 mm diameter variant within this lineup, providing a standardized form factor for general-purpose alerting systems.
Replacement Considerations
Consult the TDK Piezoelectric Buzzer Selection Guide for direct substitutes with matching 17 mm diameter, 4 kHz frequency, and 3 V rating. Verify that any alternative maintains the externally driven (no oscillator) characteristic and through-hole pin terminal style.
