SF2170D

Overview

The SF2170D is a Surface Acoustic Wave (SAW) bandpass filter designed for signal conditioning applications. It operates within a frequency range of 155 MHz to 175 MHz, with a center frequency of 165 MHz and a bandwidth of 22 MHz. The component features a 50 Ohm impedance and supports a rated voltage of 30 V. It exhibits an insertion loss of 9 dB and is housed in a compact 6-SMD, No Lead package with a maximum height of 1.70 mm. This device meets AEC-Q200 automotive reliability standards.

Feature Summary

• Surface Acoustic Wave technology for precise signal filtering
• Automotive-grade reliability compliant with AEC-Q200 standards
• Compact surface-mount design suitable for space-constrained layouts

Applications

• General purpose RF signal conditioning
• Automotive electronics systems requiring AEC-Q200 compliance
• Wireless communication interfaces operating in the 155-175 MHz range

Procurement Notes

Verify that the specific order includes the correct suffix if variant differentiation exists in official documentation. Confirm the package type matches the 6-SMD No Lead specification. Ensure the application environment aligns with the 30 V rated voltage limit. Cross-reference the AEC-Q200 rating if automotive qualification is mandatory for the end product.

Selection Notes

Select this component when a narrow bandpass characteristic centered at 165 MHz is required. The 22 MHz bandwidth defines the passband tolerance. Consider the 9 dB insertion loss impact on system gain. The 50 Ohm impedance must match the source and load networks. Verify thermal and mechanical constraints against the 1.70 mm maximum height.
