SDR433M920S001

Overview

The SDR433M920S001 is a surface-mount SAW resonator from the SDR series, manufactured by NextGen Components. It features a 3030 type package with six pads and dimensions of L3.0mm x W3.0mm x H1.25mm. The device operates at a center frequency of 433.920MHz with a frequency tolerance of ±75KHz. Key electrical specifications include a maximum insertion loss of 2.2 dB and an impedance of 50 Ohms. The component is designed for high reliability in compact electronic applications.

Feature Summary

• Utilizes Surface Acoustic Wave (SAW) technology for precise frequency control
• Features a compact 3030 surface-mount package with six connection pads
• Provides low insertion loss performance for efficient signal transmission

Applications

• Wireless communication modules operating at 433 MHz ISM band
• Remote keyless entry systems
• Industrial telemetry equipment

Procurement Notes

Verify the specific datasheet version when ordering, as frequency tolerance specifications may vary between ±50KHz and ±75KHz depending on the revision date. Confirm that the six-pad 3030 footprint matches the target PCB design. Ensure compatibility with standard reflow soldering profiles for surface-mount assembly processes to maintain device integrity.

Selection Notes

Select this component for applications requiring a 433.920MHz reference with tight frequency stability. The six-pad configuration offers improved thermal dissipation compared to two-pad variants. Consider the 3030 package size constraints against available board space. Verify that the 50 Ohm impedance aligns with the system's RF matching network requirements.

Part Context

This part belongs to the SDR series of SMD SAW resonators produced by NextGen Components. It is distinct from similar models like SER433M920S001 or SGR433M920S001, which may differ in pad count or physical height. The SDR series specifically utilizes a 3030 footprint with six pads, differentiating it from other family members that might use smaller packages or fewer connections.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with generic 433.920MHz SAW resonators requires careful verification of the six-pad 3030 footprint and specific electrical parameters such as insertion loss and frequency tolerance.
