Overview
The TDK PS1740P02E is a piezoelectric buzzer designed for through-hole PCB mounting. It operates at a rated voltage of 3 VAC with a maximum supply voltage of 30 VAC. The device produces a continuous tone at a frequency of 4 kHz, achieving a sound pressure level of 75 dBA. Physical dimensions include a 17 mm diameter and a height of 7.5 mm. It utilizes solder pin termination and functions within an operating temperature range of -10°C to 70°C.
Feature Summary
- Piezoelectric construction for external drive applications
- Through-hole solder pin termination for PCB integration
- Continuous tone generation capability
Applications
- General electronic equipment audio alerts
- Industrial control panel indicators
- Consumer appliance status signaling
Procurement Notes
Verify the specific suffix E against the official TDK datasheet to confirm RoHS compliance and material composition details. Ensure the external driver circuit supports the 3 VAC rating and 4 kHz frequency requirements. Confirm that the through-hole footprint matches the 17 mm diameter and 7.5 mm height specifications during PCB layout design.
Selection Notes
Select this component when a passive piezoelectric element requiring external oscillation is necessary. The 3 VAC rating suits low-voltage logic systems. Consider the 75 dBA output for environments requiring moderate audibility. Verify that the operating temperature range of -10°C to 70°C aligns with the target application's environmental conditions.
Part Context
This part belongs to the TDK PS series of piezoelectric buzzers. The series offers various diameters and frequencies for different acoustic needs. The PS1740P02E specifically targets compact designs requiring a 17 mm form factor. It serves as a standard audio indicator component in general-purpose electronics manufacturing.
Replacement Considerations
Consult the TDK PS series selection guide for alternative models with matching 17 mm diameter and 4 kHz frequency. Verify mechanical compatibility before substituting with other manufacturers' parts.
