32S4120LFPN

Overview

The DB Products 32S4120LFPN is an internally driven piezo buzzer designed for through-hole mounting. It operates within a voltage range of 3 to 16 VDC, with a rated voltage of 12 VDC. The component draws a current of 7 mA and produces a sound pressure level of 80 dB at 12V measured from a distance of 10 cm. It generates a single tone at a frequency of 4 kHz.

Feature Summary

• Internally driven piezo technology eliminates the need for external oscillators
• Single tone output capability for distinct audible alerts
• Through-hole PC pin construction for secure board integration

Applications

• Electronic appliance status indicators
• Security system alarm outputs
• Industrial control panel signaling

Procurement Notes

Verify the specific suffix LFPN against the manufacturer's latest datasheet to confirm lead-free compliance and pin configuration. Ensure the operating voltage remains within the 3-16 VDC range to prevent damage. Cross-reference the 80 dB specification at 10 cm with acoustic requirements for the intended enclosure environment.

Selection Notes

Select this component when an integrated driver is required to simplify circuit design. The 12 VDC rating suits standard logic or power supply rails. Consider the 4 kHz frequency for optimal human hearing sensitivity in noisy environments. Verify mechanical fit for through-hole PCB layouts before finalizing the bill of materials.

Part Context

This part belongs to the DB Products piezo buzzer series, which focuses on combining acoustic performance with electronic simplicity. The manufacturer emphasizes integrating human hearing sensations with electronic components to create reliable signaling devices for various industrial and consumer applications.

Replacement Considerations

The 32SC4120LFPP is listed as a related model in official documentation. Verify if the LFPP variant offers identical electrical characteristics and physical dimensions before substitution.
