SF2172C

Overview

The Murata Electronics SF2172C is a Surface Acoustic Wave (SAW) filter designed for RF applications. It operates at a center frequency of 280 MHz with a bandwidth of 19.8 MHz. The component exhibits an insertion loss of 8.8 dB and is housed in an 8-SMD surface-mount package.

Feature Summary

• Utilizes SAW technology for RF signal filtering
• Optimized for general-purpose RF applications
• Surface mount configuration for PCB integration

Applications

• General purpose RF signal processing
• RF front-end filtering systems

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Murata Electronics or authorized distributors before procurement. Confirm that the 8-SMD package dimensions and pinout match the target PCB layout requirements to ensure mechanical compatibility.

Selection Notes

Select this component when a 280 MHz center frequency and 19.8 MHz bandwidth are required for RF filtering. Consider the 8.8 dB insertion loss impact on system gain. Ensure the design accommodates the 8-SMD footprint and surface-mount assembly processes.

Part Context

This part belongs to Murata's EMIFIL family of passive components, specifically within the SAW filter category. It is distinct from Murata's ceramic or feed-through capacitors and common mode chokes, serving primarily as a frequency-selective element in radio frequency circuits rather than for EMI suppression or power line filtering.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
