SBR433M920S021

Overview

The SBR433M920S021 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components. It operates at a nominal frequency of 433.92 MHz with a frequency tolerance of ±50 kHz. The device features a 50 Ohm impedance and a maximum insertion loss of 2.0 dB. It is designed for surface mount applications, utilizing a 6-pad configuration within the SBR series. The physical dimensions are specified as L3.8mm x W3.8mm x H1.50mm, corresponding to the 3838 package type. The component supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise frequency generation
• Compact surface mount design with six electrical pads
• Optimized for low insertion loss performance
• Operates reliably across extended industrial temperature ranges

Applications

• ISM band wireless communication modules
• Remote keyless entry systems
• Industrial telemetry transmitters
• Short-range radio control devices

Procurement Notes

Verify the specific ordering suffix against official NextGen Components documentation to ensure correct frequency tolerance and packaging specifications. Confirm that the required frequency stability aligns with system requirements, as standard variants may differ. Check for active product status confirmation prior to procurement to avoid obsolescence risks. Ensure compatibility with automated pick-and-place equipment given the small surface mount footprint.

Selection Notes

Select this component when a stable 433.92 MHz reference is required for ISM band applications. Consider the ±50 kHz tolerance relative to channel spacing requirements in the target design. Evaluate the thermal management capabilities of the PCB layout to maintain operation within the -40°C to +85°C range. Compare insertion loss specifications against transmitter power budgets to ensure signal integrity.

Part Context

This part belongs to the SBR series of SAW resonators from NextGen Components. It is distinct from crystal oscillators or filters, serving specifically as a passive resonant element. The 3838 package size allows for high-density mounting on printed circuit boards. It complements other components in the SBR family which offer different frequencies and pad configurations.

Replacement Considerations

Direct substitutes must match the 433.92 MHz frequency, 50 Ohm impedance, and 3838 package dimensions. Verify pinout compatibility for the six-pad configuration. Cross-reference with other manufacturers' SAW resonators offering identical frequency tolerances and insertion loss characteristics.
