SDR433M920S011

Overview

The SDR433M920S011 is a Surface Mount Device (SMD) SAW resonator from the NextGen Components SDR series. It operates at a center frequency of 433.920 MHz with a frequency tolerance of ±50 kHz. The component features a 6-pad configuration in a 3030 type package, measuring 3.0 mm in length, 3.0 mm in width, and 1.25 mm in height. It is designed as a 1-port device with a maximum insertion loss of 2.0 dB.

Feature Summary

• Surface mount SAW resonator technology
• Six-pad electrode configuration for stability
• Compact 3030 package dimensions

Applications

• RF signal filtering in wireless communication modules
• Frequency reference in IoT devices
• Signal processing in remote control systems

Procurement Notes

Verify the specific suffix 'S011' against manufacturer documentation to confirm the ±50 kHz tolerance and 6-pad specification. Ensure compatibility with surface mount reflow processes given the 3030 package profile. Confirm that the 1-port configuration meets the circuit design requirements for insertion loss and impedance matching.

Selection Notes

Select this component when a 433.92 MHz SAW resonator with tight ±50 kHz tolerance is required. The 6-pad design offers mechanical stability compared to 2-pad alternatives. Consider the 2.0 dB max insertion loss for system sensitivity calculations. Verify operating temperature range suitability for the intended environment.

Part Context

This part belongs to the SDR series of SMD SAW resonators manufactured by NextGen Components. The series includes variants with different tolerances and pad counts, such as the SGR433M920S001 which features a 2-pad configuration. The SDR433M920S011 specifically denotes the 6-pad version with ±50 kHz tolerance.

Replacement Considerations

The SGR433M920S001 is a related variant but uses a 2-pad configuration instead of 6 pads. Cross-reference with other 6-pad 3030 SAW resonators if footprint changes are acceptable. Verify electrical parameters match exactly before substitution.
