SF16-0908M4UU01

Overview

The SF16-0908M4UU01 is a Surface Acoustic Wave (SAW) filter manufactured by KYOCERA AVX, designed for general-purpose RF signal conditioning applications. It operates at a center frequency of 908.42 MHz with a bandwidth of 19 MHz and an insertion loss of 2.3 dB. The component utilizes a 4-terminal SMD package suitable for board mounting. It belongs to the SF16 series and exhibits moisture sensitivity. The device is rated for operation within a temperature range of -30°C to +85°C and maintains a system impedance of 50 Ohms.

Feature Summary

• Provides precise RF signal filtering using surface acoustic wave technology
• Optimized for compact surface-mount integration in electronic assemblies
• Designed for stable performance across specified industrial temperature ranges

Applications

• General-purpose RF signal conditioning circuits
• Wireless communication modules operating near 900 MHz bands
• Industrial control systems requiring signal isolation

Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited distribution channels. Confirm that the 4SMD package dimensions align with existing PCB footprints. Ensure environmental compliance requirements match project specifications. Validate that the operating temperature range meets the final assembly conditions. Check for updated datasheets regarding handling precautions due to moisture sensitivity classification.

Selection Notes

Select this component when a narrow-band SAW filter is required for frequencies around 908 MHz. Consider the 19 MHz bandwidth relative to adjacent channel interference requirements. Evaluate the 2.3 dB insertion loss impact on overall link budget. Compare physical size constraints against alternative packages in the SF16 series. Assess thermal management needs given the specified operating temperature limits.
