H140XHXS-T

Overview

The H140XHXS-T is a surface mount high-pass filter manufactured by Knowles Dielectric Labs. It operates at a cutoff frequency of 14 GHz with a 50 Ohm impedance. The component features an insertion loss of 1.5 dB and supports board mounting via SMD/SMT termination. It functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides sharp signal attenuation below the 14 GHz cutoff frequency
• Designed for surface mount integration on printed circuit boards
• Operates reliably across extended industrial temperature ranges

Applications

• RF signal conditioning in microwave communication systems
• High-frequency filtering in radar equipment
• Signal integrity management in satellite transponders

Procurement Notes

Verify the specific suffix 'T' against official manufacturer documentation to confirm reel packaging specifications. Ensure compatibility with standard SMD reflow profiles. Confirm RoHS compliance status through current datasheets before procurement planning.

Selection Notes

Select this component when a precise 14 GHz high-pass characteristic is required in a compact form factor. Evaluate the 1.5 dB insertion loss against system link budget requirements. Ensure the PCB layout accommodates the specific SMD footprint dimensions provided in the mechanical drawings.

Part Context

This part belongs to the Knowles Dielectric Labs RF filter portfolio, specifically designed for high-frequency applications. It complements other bandpass and low-pass variants within the same product line, offering specialized high-frequency rejection capabilities for modern wireless infrastructure.

Replacement Considerations

Consult official substitution guides for equivalent high-pass filters from the same manufacturer family. Verify that any alternative part maintains identical 14 GHz cutoff characteristics and 50 Ohm impedance matching.
