HFCV-145+

Overview

The HFCV-145+ is a surface-mount high-pass ceramic filter manufactured by Mini-Circuits. It utilizes LTCC technology with a seven-section design to achieve a low-frequency cutoff of 140 MHz and a high-frequency limit of 1150 MHz. The component operates at a standard impedance of 50 Ohms and features a typical stop-band rejection of 23 dB. Packaged in a compact 1210 (3225 Metric) footprint, it supports RoHS and REACH compliance for modern electronic assembly requirements.

Feature Summary

• LTCC-based seven-section architecture for extended low-frequency cutoff performance
• Surface-mount construction suitable for automated PCB assembly
• RoHS and REACH compliant material composition

Applications

• RF signal conditioning circuits requiring high-pass filtering
• Wireless communication systems operating within the specified frequency range
• Microwave component integration in RF front-end modules

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may issue Product Change Notices affecting materials or specifications. Confirm that the required package variant matches the 1210 footprint dimensions. Ensure compatibility with the target impedance and frequency parameters before finalizing procurement decisions.

Selection Notes

Select this component when a sharp high-pass response is needed starting from 140 MHz. The LTCC construction offers stability compared to discrete LC solutions. Verify that the 50 Ohm system impedance aligns with the rest of the circuit design to minimize reflection losses.

Part Context

This part belongs to Mini-Circuits' line of LTCC high-pass filters designed for RF and microwave applications. These components are engineered to replace bulkier discrete filter networks while providing reliable signal integrity in compact form factors.

Replacement Considerations

Consult official Mini-Circuits documentation for confirmed substitute part numbers. Do not assume functional equivalence with other high-pass filters without verifying cutoff frequencies and impedance matching.
