RDTE-4.000-3030-NS1

Overview

The RDTE-4.000-3030-NS1 is an externally driven magnetic transducer manufactured by Raltron Electronics. It operates at a nominal voltage of 3 V with a current draw of 120 mA. The device produces an acoustic output of 72 dB measured at 3 V and 10 cm surface distance. Its resonant frequency is 4 kHz. The component utilizes a surface mount package with dimensions of 0.12 inches by 0.12 inches.

Feature Summary

• Externally driven magnetic transducer design
• Surface mount solder pad termination
• Side port location for acoustic output

Applications

• Electronic alarm systems
• Audible notification devices
• Consumer electronics audio signaling

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and variant selection. Confirm that the external drive circuitry matches the 3 V nominal voltage and 120 mA current requirements. Ensure PCB layout accommodates the 0.12 inch by 0.12 inch footprint and side port orientation for proper acoustic performance.

Selection Notes

Select this component when a compact, low-voltage audible indicator is required. The 4 kHz resonant frequency provides distinct audibility. Compare against other RDTE series variants if different sound pressure levels or physical dimensions are needed. Ensure the application supports external driving rather than integrated oscillator circuits.

Part Context

This part belongs to the RDTE series of magnetic transducers from Raltron Electronics. The series includes various sizes and electrical specifications. The RDTE-4.000-3030-NS1 represents a specific size and performance tier within this family, distinguished by its 3V operation and 72 dB output level.

Replacement Considerations

Direct substitutes include RDTE-4.000-5050-NS1 and RDTE-4.000-4040-NS1. Verify dimensional compatibility and acoustic output differences before substitution.
