HFCN-2100+

Overview

The HFCN-2100+ is a high-pass ceramic filter manufactured by Mini-Circuits. It features a center frequency of 4.1 GHz and a bandwidth of 3.8 GHz. The component operates at a nominal impedance of 50 Ohms. It is housed in a compact 4-SMD, no-lead package with dimensions of 3.20mm x 1.60mm x 0.94mm maximum height. The device utilizes Low-Temperature Co-Fired Ceramic (LTCC) technology for surface mount installation.

Feature Summary

• Utilizes LTCC technology for robust surface mount construction
• Designed as a high-pass filter to block lower frequencies
• Optimized for 50 Ohm system impedance applications

Applications

• RF signal filtering in communication systems
• Microwave circuit integration
• High-frequency interference suppression

Procurement Notes

Verify the specific ordering suffix required for your packaging needs, such as tape-and-reel or cut-tape options. Confirm RoHS3 compliance status if environmental regulations apply to your assembly process. Ensure the selected variant matches the required operating temperature range and physical footprint constraints for your PCB layout design.

Selection Notes

Select this component when a high-pass characteristic centered around 4.1 GHz is required. The 50 Ohm impedance rating ensures compatibility with standard RF transmission lines. Consider the small SMD footprint for space-constrained designs. Verify that the operating frequency range covers the desired signal spectrum above the cutoff point.

Part Context

This part belongs to the HFCN series of LTCC high-pass filters from Mini-Circuits. These components are designed for RF and microwave applications requiring reliable frequency selection. The series offers various cutoff frequencies to suit different band requirements while maintaining consistent electrical performance across the product line.

Replacement Considerations

Check for alternate qualified ceramic substrate materials as noted in recent product change notices. Ensure any substitute maintains the same 4-SMD no-lead package and 50 Ohm impedance characteristics.
