SF2416D

Overview

The SF2416D is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi, designed for general-purpose radio frequency applications. It operates at a central frequency of 490 MHz with a bandwidth of 20 MHz, covering a range from 480 MHz to 500 MHz. The component features an insertion loss of 2.4 dB and supports a rated voltage of 3 V. Packaged in a surface-mount technology (SMT) SM3838-8 case measuring 3.8 mm by 3.8 mm with a maximum height of 1.40 mm, it provides signal conditioning for 50 Ohm systems.

Feature Summary

• Utilizes Surface Acoustic Wave (SAW) technology for precise signal filtering
• Optimized for low insertion loss to maintain signal integrity
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• General purpose RF signal conditioning
• Wireless communication device front-ends
• Radio frequency interference suppression

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Ensure the ordering suffix matches the required packaging configuration. Confirm that the SM3838-8 package dimensions align with your board layout constraints. Cross-reference the electrical specifications against your system requirements to ensure compatibility with the 490 MHz center frequency and 20 MHz bandwidth.

Selection Notes

Select this component when a SAW filter is required for the 480-500 MHz range with minimal insertion loss. The 3.8x3.8 mm footprint offers a compact solution for SMT assembly processes. Consider the 3 V rated voltage and 50 Ohm impedance matching when integrating into existing RF circuits. Evaluate the thermal and mechanical stability provided by the surface-mount construction for long-term reliability in portable devices.
