SDF433M92S4001

Overview

The SDF433M92S4001 is a Surface Acoustic Wave (SAW) filter manufactured by NextGen Components. It operates at a center frequency of 433.92 MHz with a maximum insertion loss of 1.8 dB and a bandwidth of 4 MHz. The component utilizes a 6-pad SMD package in the 3030 type configuration, measuring 3.0 mm in length, 3.0 mm in width, and 1.25 mm in height.

Feature Summary

• Utilizes Surface Acoustic Wave technology for RF filtering applications
• Designed for wireless communication systems requiring precise frequency selection
• Compact surface-mount construction suitable for automated assembly

Applications

• Wireless RF signal processing
• ISM band communication devices
• Remote control systems operating at 433 MHz

Procurement Notes

Verify the specific datasheet version when ordering, as documentation indicates variations such as SIR433M920S041 with different insertion loss specifications. Confirm the exact center frequency requirement of 433.92 MHz versus 433.29 MHz to ensure compatibility with your system design before finalizing procurement.

Selection Notes

Select this component for designs requiring a 3x3 mm footprint with a low profile of 1.25 mm. Ensure the application can accommodate the specified 4 MHz bandwidth and 1.8 dB insertion loss characteristics. Verify that the 6-pad SMD termination style matches the PCB land pattern requirements.
