SF2214E

Overview

The SF2214E is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 815 MHz with a bandwidth of 20 MHz, covering a range from 805 MHz to 825 MHz. The component features a 50 Ohm impedance and an insertion loss of 2.8 dB. It is rated for 5 V and utilizes an SM-3030-6 surface-mount package. The device supports board mounting and functions within a temperature range of -30°C to +75°C.

Feature Summary

• Surface Acoustic Wave technology for signal conditioning
• AEC-Q200 automotive qualification standard compliance
• Compact SM-3030-6 surface-mount packaging

Applications

• General purpose RF applications
• Automotive electronics systems
• Wireless communication modules

Procurement Notes

Verify the specific datasheet version provided by RFMi or authorized distributors to confirm exact electrical tolerances and RoHS compliance status. Ensure the ordering suffix matches the required tape and reel configuration. Cross-reference the AEC-Q200 certification details if the application demands strict automotive reliability standards before finalizing procurement.

Selection Notes

Select this component when a 815 MHz center frequency with a narrow 20 MHz bandwidth is required for RF filtering. The 50 Ohm impedance ensures compatibility with standard transmission lines. Consider the SM-3030-6 footprint for space-constrained designs. Verify that the 2.8 dB insertion loss meets system sensitivity requirements and that the operating temperature range aligns with environmental conditions.

Part Context

This part belongs to the SF series of SAW filters from RFMi, designed for signal conditioning in RF circuits. It is distinct from other models like the SF2236E, which targets different frequency bands such as 1.6 GHz ranges. The SF series generally offers compact SMD solutions for various wireless standards.
