SF2180D

Overview

The RFMi SF2180D is a low-loss surface acoustic wave (SAW) filter designed for precise signal conditioning in the 700 MHz frequency range. It operates within a bandwidth of 3.5 MHz, centered at 700 MHz, with a specified frequency range of 698.25 MHz to 701.75 MHz. The component features a 50 Ohm impedance and supports a rated voltage of 30 V. Packaged in a compact 3.8×3.8×1.4mm SMD ceramic housing with eight terminals, it meets AEC-Q200 automotive reliability standards and complies with RoHS environmental directives.

Feature Summary

• Low insertion loss performance for efficient signal transmission
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact surface-mount ceramic package suitable for space-constrained designs

Applications

• Wireless communication systems requiring 700 MHz band filtering
• Automotive electronic modules demanding high reliability
• OEM devices integrating internet-connected wireless functionality

Procurement Notes

Verify that the specific order includes the correct suffix indicating tape and reel packaging if automated assembly is required. Confirm compliance with current RoHS directives and ensure storage conditions respect moisture sensitivity level 1. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during procurement.

Selection Notes

Select this component when a narrow 3.5 MHz bandwidth is required around 700 MHz with minimal signal attenuation. The 50 Ohm impedance matches standard RF system architectures. Consider the small footprint for dense PCB layouts and the automotive qualification for harsh environment applications where long-term stability is critical.
