HFCN-1910D+

Overview

The HFCN-1910D+ is a ceramic high-pass filter manufactured by Mini-Circuits, designed for RF applications. It operates within a passband of 2000 to 5200 MHz and features a center frequency of 3.6 GHz. The component utilizes low-temperature co-fired ceramic (LTCC) technology and is housed in a compact 4-SMD, no lead surface-mount package. It maintains a standard system impedance of 50 Ohms with a bandwidth of 3.2 GHz. This filter effectively suppresses low-frequency interference while allowing higher frequencies to pass, ensuring signal integrity in wireless communication systems.

Feature Summary

• Utilizes low-temperature co-fired ceramic (LTCC) technology for stable performance
• Provides effective suppression of low-frequency interference and clutter
• Designed for compact surface-mount integration in RF circuits

Applications

• Wireless communication systems
• RF test equipment
• IoT terminals

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may be updated. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Ensure compatibility with standard reflow soldering profiles suitable for LTCC components. Cross-reference the part number suffix to confirm it denotes the standard commercial grade variant without special handling or packaging modifications.

Selection Notes

Select this component when a high-pass response between 2000 and 5200 MHz is required. The 50 Ohm impedance rating makes it suitable for standard RF transmission lines. Consider the small SMD form factor for space-constrained designs. Evaluate the LTCC construction for thermal stability in varying environmental conditions compared to other filter technologies.

Part Context

This component belongs to the HFCN series of high-pass filters from Mini-Circuits. The series leverages LTCC technology to offer compact solutions for RF filtering. These filters are part of a broader portfolio that includes low-pass variants and other passive RF devices, supporting comprehensive signal chain design for commercial and industrial projects.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Generic equivalents may not match the precise LTCC characteristics or impedance matching of the original component.
