SF2349D

Overview

The SF2349D is a surface acoustic wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 912.1 MHz with a bandwidth of 10.2 MHz, covering a range from 907 MHz to 917.2 MHz. The device features a 5 V voltage rating and an insertion loss of 2.95 dB. It utilizes a 6-SMD, no-lead package with dimensions of 3.80mm x 3.80mm x 1.70mm. Designed for board mounting, it supports an operating temperature range from -45°C to +85°C.

Feature Summary

• Surface acoustic wave technology for precise signal conditioning
• General-purpose RF filtering capability
• Compact SMD package design

Applications

• Wireless communication systems
• Internet-connected OEM devices
• RF signal processing modules

Procurement Notes

Verify the manufacturer designation as RFMi, which is an Akoustis brand. Confirm the specific package type is 6-SMD, no-lead, and matches the required footprint dimensions of 3.80mm x 3.80mm. Ensure the operating temperature range meets the application requirements of -45°C to +85°C. Cross-reference the center frequency of 912.1 MHz against system specifications.

Selection Notes

Select this component when a SAW filter with a 912.1 MHz center frequency is required. The 10.2 MHz bandwidth suits applications needing moderate selectivity. The 5 V rating and low insertion loss are suitable for general-purpose RF stages. Consider the SMD package size for PCB layout constraints.
