SF2464E

Overview

The SF2464E is a surface acoustic wave (SAW) bandpass filter manufactured by RFMi, designed for signal conditioning applications. It operates at a center frequency of 400 MHz with a bandwidth ranging from 399.875 MHz to 400.125 MHz. The component features an impedance of 328 Ohms and a voltage rating of 6 V. Key electrical specifications include an insertion loss of 3.5 dB and a bandwidth of 680 kHz. It utilizes SMD/SMT termination types and is housed in an SM3030-6 package. The device supports board mounting and functions within a temperature range of -45 C to +125 C.

Feature Summary

• Surface acoustic wave technology for general-purpose RF filtering
• AEC-Q200 automotive qualification rating
• Compact six-terminal leadless surface mount design

Applications

• General-purpose RF signal conditioning
• Automotive electronics systems requiring AEC-Q200 compliance
• Wireless communication devices operating near 400 MHz

Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm exact insertion loss values, as sources vary between 2.8 dB and 3.5 dB. Ensure the required packaging format matches the available reel quantities. Confirm that the 328 Ohm impedance aligns with your circuit design requirements before ordering.

Selection Notes

Select this component when a narrowband SAW filter centered at 400 MHz is required for automotive or industrial environments. The SM3030-6 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the 328 Ohm impedance match carefully to ensure optimal signal transmission and minimal reflection in the target application circuit.
