748111009

Overview

The Würth Elektronik 748111009 is a WE-LPF series multilayer chip low-pass RF filter designed for signal conditioning applications. It operates within the 902 MHz to 928 MHz frequency range and utilizes an 0805 [2012 Metric] surface-mount package with eight pins. The component functions as a band-pass filter, providing specific attenuation characteristics for radio frequency signals in compact electronic designs.

Feature Summary

• Multilayer chip construction for reliable surface-mount integration
• Designed for signal conditioning in radio frequency circuits
• Compact 0805 footprint suitable for space-constrained layouts

Applications

• RF signal filtering in wireless communication modules
• Signal conditioning for transceivers operating in the 900 MHz ISM band
• Noise suppression in RF front-end circuits

Procurement Notes

Verify the exact impedance profile and S-parameter data against the official Wurth Elektronik datasheet before finalizing the design. Confirm that the 0805 package dimensions align with your PCB fabrication capabilities. Ensure the supplier provides traceable documentation matching the manufacturer's part number to avoid counterfeit components.

Selection Notes

Select this component when a low-pass or band-pass characteristic is required specifically around the 900 MHz range. The 0805 size offers a balance between performance and board space. Consider thermal management requirements during reflow soldering, as multilayer ceramic filters have specific thermal profiles.

Part Context

This component belongs to the WE-LPF series from Würth Elektronik, which specializes in passive RF components. The series includes various filter types tailored for different frequency bands and package sizes, supporting modern telecommunications and IoT device architectures.

Replacement Considerations

Consult the official Wurth Elektronik cross-reference guide for verified substitutes. Do not assume functional equivalence with generic 0805 filters without verifying S-parameter overlap.
