SF2038C-1

Overview

The RFMi SF2038C-1 is a Surface Acoustic Wave (SAW) filter designed for signal conditioning applications. It operates at a center frequency of 76.5 MHz with a defined range of 70.5 MHz to 82.5 MHz. The component features a bandwidth of 12.7 MHz and supports impedances of 175 Ohms and 180 Ohms. It has a voltage rating of 30 V and is housed in an 8-SMD package. The device is qualified under AEC-Q200 standards, indicating suitability for automotive environments.

Feature Summary

• Surface Acoustic Wave technology for precise signal filtering
• AEC-Q200 qualification for automotive reliability
• Compact 8-SMD surface mount packaging

Applications

• Automotive intermediate frequency filtering
• Signal conditioning in communication systems
• RF front-end modules requiring 76.5 MHz selectivity

Procurement Notes

Verify the specific datasheet version for exact insertion loss and return loss values, as these can vary by manufacturing lot. Confirm that the 175/180 Ohm impedance matches your circuit design requirements. Ensure the 8-SMD footprint aligns with your PCB layout constraints. Check RoHS compliance status if environmental regulations apply to your assembly process.

Selection Notes

Select this component when a narrow bandpass filter centered at 76.5 MHz is required for automotive or industrial applications. The AEC-Q200 qualification makes it suitable for harsh environments. Consider the 12.7 MHz bandwidth relative to your signal spectrum needs. The SMD package facilitates automated assembly processes.
