SCHF-31+

Overview

SCHF-31+ is a 50Ω lumped LC high pass filter fabricated using surface mount technology. It operates within a frequency range of 31 MHz to 1500 MHz. The component utilizes high Q inductors and capacitors to achieve effective signal filtering characteristics suitable for radio frequency applications.

Feature Summary

• Surface mount construction for automated PCB assembly
• Lumped LC topology for compact form factor
• High Q components for efficient filtering performance

Applications

• RF signal conditioning circuits
• Communication system front ends
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version for precise insertion loss and return loss values at critical frequencies. Confirm package dimensions against your PCB footprint requirements. Ensure compatibility with standard reflow soldering profiles for SMT components. Check for RoHS compliance markings on the packaging documentation.

Selection Notes

Select this component when a sharp cutoff above 31 MHz is required in a 50Ω system. Consider the physical size constraints of the SMD package relative to available board space. Evaluate thermal management needs if operating near maximum power ratings defined in the official specifications.

Part Context

Mini-Circuits manufactures RF and microwave components including filters, amplifiers, and mixers. The SCHF series represents their line of lumped element high pass filters designed for general-purpose RF applications. These components are widely used in communication infrastructure and test equipment.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes such as SCHF-27+. Verify that alternative parts match the 31 MHz cutoff frequency and 50Ω impedance. Ensure package compatibility before replacing existing inventory.
