Overview
The RDTE-4.000-4040-NS1 is a surface-mount magnetic transducer buzzer manufactured by Raltron Electronics. It operates at a nominal frequency of 4 kHz and requires an external drive circuit. The device functions with a supply voltage of 3 VDC and draws a current of 90 mA. It delivers a sound pressure level of 70 dB when measured at a distance of 10 cm under the specified voltage conditions. The component utilizes solder pads for mounting, distinguishing it from through-hole or leaded alternatives in alarm and signaling applications.
Feature Summary
- Externally driven magnetic transducer design requiring external oscillator circuitry
- Surface mount construction utilizing solder pads for PCB integration
- Operates on a standard 3 VDC supply with defined current consumption
Applications
- Electronic alarm systems
- Audible warning devices
- Buzzer assemblies in consumer electronics
Procurement Notes
Verify the specific suffix requirements against the manufacturer's latest datasheet to ensure correct acoustic and electrical specifications. Confirm that the application circuit provides the necessary external drive signal, as this component is an externally driven transducer rather than a self-oscillating unit. Check package compatibility with existing PCB footprints before finalizing procurement decisions.
Selection Notes
Select this component when a compact, surface-mount magnetic buzzer is required for audible signaling. Ensure the design includes an external driver capable of supplying 90 mA at 3 VDC. Consider the 70 dB output level at 10 cm for noise requirements. This part is suitable for space-constrained designs where traditional through-hole buzzers are not feasible.
Part Context
Raltron Electronics produces a range of electromagnetic transducers and buzzers for industrial and consumer markets. The RDTE series represents their surface-mount magnetic buzzer line, designed for automated assembly processes. These components serve as core acoustic elements in various alerting devices, offering reliability in standard operating environments.
Replacement Considerations
Consult official substitution lists for equivalent surface-mount magnetic buzzers with matching 4 kHz frequency and 3 VDC operation. Verify that any alternative maintains the same 90 mA current draw and 70 dB acoustic output to ensure system performance consistency.
