L117XH4W-T

Overview

The L117XH4W-T is a wirebond lowpass filter manufactured by Knowles Dielectric Labs, designed for signal conditioning applications. It features a cutoff frequency of 11.7 GHz and operates with a characteristic impedance of 50 Ohms. The component utilizes SMD/SMT termination styles for board mounting and offers an insertion loss of 0.8 dB. It functions within a temperature range from -55°C to +125°C. The device is supplied in reel packaging, facilitating automated assembly processes for high-frequency RF systems requiring precise spectral filtering.

Feature Summary

• Wirebond construction for reliable high-frequency performance
• Low insertion loss characteristics for minimal signal degradation
• Wide operating temperature range suitable for harsh environments

Applications

• RF signal conditioning circuits
• High-frequency communication systems
• Spectral filtering in microwave applications

Procurement Notes

Verify availability status as supply may be restricted or limited depending on the region. Confirm that the specific suffix indicates the tape and reel packaging format. Ensure compatibility with existing board layouts regarding the 10-SMD no-lead footprint. Check for any specific handling requirements due to the wirebond technology used in the component's construction.

Selection Notes

Select this component when a sharp cutoff near 11.7 GHz is required with low signal attenuation. Consider the 50 Ohm impedance match for standard RF transmission lines. Evaluate the thermal stability provided by the wide operating temperature range against environmental conditions. Compare the physical dimensions and mounting style against available space constraints on the printed circuit board.

Part Context

This part belongs to the Lowpass Filters series from Knowles Dielectric Labs, focusing on signal conditioning solutions. It is distinct from general-purpose filters by its specific optimization for high-frequency wirebond applications. The product line emphasizes reliability and precision in RF environments, catering to specialized electronic design needs rather than generic consumer electronics.

Replacement Considerations

Consult official substitution lists for compatible alternatives. Verify electrical parameters such as cutoff frequency and impedance before swapping components. Ensure mechanical fit and pinout compatibility if replacing with similar models from other manufacturers.
