RDT-4.000-1206-NS1

Overview

The RDT-4.000-1206-NS1 is an externally driven piezo transducer manufactured by Raltron Electronics. It features a 12.6mm outer diameter and 6mm height, designed for through-hole mounting via PC pins. The device operates at a resonant frequency of 4kHz with a nominal voltage of 3V and current consumption of 3mA. It produces a sound pressure level of 75dB when measured at 3V from a distance of 10cm.

Feature Summary

• Externally driven piezoelectric design
• Through-hole PC pin termination
• Compact cylindrical form factor

Applications

• Audible alarm systems
• Buzzer circuits
• Siren devices

Procurement Notes

Verify the specific datasheet for detailed electrical characteristics and mechanical drawings before integration. Confirm that the through-hole PC pin configuration matches your PCB layout requirements. Ensure the operating environment supports the specified 3V nominal voltage and 4kHz resonant frequency for optimal acoustic performance.

Selection Notes

Select this component for applications requiring a simple, externally driven acoustic output without integrated drivers. The through-hole mounting style suits prototyping or boards designed for standard pin headers. Consider the 75dB SPL rating to ensure adequate audibility for the intended enclosure size and ambient noise levels.

Part Context

This part belongs to the Raltron Electronics RDT series of piezo transducers. These components are categorized under alarms, buzzers, and sirens within audio product lines. The series offers various dimensions and frequencies to accommodate different acoustic and spatial constraints in electronic assemblies.

Replacement Considerations

Consult official substitution lists for compatible alternatives. Verify that any replacement maintains the same 4kHz resonant frequency, 3V operation, and through-hole mounting interface to ensure functional equivalence in existing designs.
