186PZ14330LFRMP

Overview

The DB Products 186PZ14330LFRMP is an externally driven piezoelectric transducer designed for surface-mount applications. It features a rectangular footprint measuring 14x14mm with a height of 11mm. The device operates at a resonant frequency of 3.3kHz and delivers a sound pressure level of 80dB when tested at 5V peak-to-peak at a distance of 10cm. It supports a maximum input voltage of 30.0 Vp-p and draws a current of 5mA during operation.

Feature Summary

• Surface-mount piezoelectric transducer construction
• Externally driven acoustic output mechanism
• Rectangular SMD package design

Applications

• Electronic alarm systems
• Audible warning devices
• Buzzer assemblies

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required mounting configurations and acoustic specifications. Confirm that the external driving circuitry can provide the necessary voltage swing without exceeding the 30Vpp limit. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a compact, surface-mount piezo element is required for audible signaling. Ensure the application environment accommodates the 14x14mm footprint and 11mm height constraints. Verify that the driving electronics can handle the 3.3kHz resonant frequency efficiently to achieve the specified 80dB output level.

Part Context

DB Products Limited specializes in acoustic components, including buzzers, piezo elements, and microphones. This part belongs to their range of externally driven piezo transducers, which are distinct from self-exciting or internally driven active buzzers. The manufacturer has been producing such components since 1976.
