SF1183E

Overview

The SF1183E is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed for signal conditioning applications. It operates at a center frequency of 881.5 MHz with a bandwidth ranging from 869 MHz to 894 MHz. The component features a 50 Ohm impedance and a voltage rating of 5 V. Key electrical specifications include an insertion loss of 3.0 dB. It is housed in an SM3030 surface-mount package (6-SMD, no lead). The device supports board mounting and functions within a temperature range of -45°C to +125°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF signal filtering
• Optimized for operation within the 869 MHz to 894 MHz frequency band
• Designed for high-temperature stability up to +125°C
• Compact surface-mount construction suitable for space-constrained PCB layouts

Applications

• RF signal conditioning in wireless communication modules
• Filtering stages in transceivers operating near 881.5 MHz
• Signal integrity enhancement in IoT devices requiring SAW filtering

Procurement Notes

Verify the manufacturer designation as Akoustis-RFMi or RFMi depending on the specific supply chain source. Confirm the package type is SM3030 (6-SMD) and matches the required footprint. Ensure the datasheet version aligns with the requested insertion loss and bandwidth parameters. Check for AEC-Q200 compliance if automotive qualification is required. Validate RoHS status through official documentation before integration.

Selection Notes

Select this component when a narrow-band SAW filter is needed for frequencies around 881.5 MHz. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the SM3030 package size for assembly constraints. The wide operating temperature range makes it suitable for industrial environments. Verify that the 3.0 dB insertion loss meets system power budget requirements.

Part Context

The SF1183E belongs to the SF series of SAW filters produced by RFMi. These components are engineered for general-purpose RF applications requiring reliable frequency selection. The product line emphasizes compact form factors and stable performance across varying thermal conditions. This specific model targets markets needing precise filtering in the sub-GHz spectrum.

Replacement Considerations
