HFCN-740D+

Overview

The HFCN-740D+ is an LTCC high-pass ceramic filter manufactured by Mini-Circuits. It operates with a center frequency of 1.79 GHz and provides a bandwidth of 2.02 GHz. The device supports a system impedance of 50 Ohms and utilizes a 4-SMD, no-lead surface-mount package. Its physical dimensions are 3.20 mm in length, 1.60 mm in width, and a maximum height of 0.94 mm. The component features DC blocking capabilities at both input and output ports with a typical breakdown voltage of 1 kV.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for stable performance across temperature variations.
• Provides excellent power handling capability rated at 7W.
• Incorporates DC blocking functionality at both input and output terminals.

Applications

• EMI/RFI suppression circuits
• Power line filtering applications
• High-frequency signal path conditioning

Procurement Notes

Verify the specific suffix 'D+' against official Mini-Circuits documentation to confirm the exact variant specifications. Ensure the procurement channel sources genuine components from authorized distributors to guarantee authenticity and compliance with RoHS3 standards. Cross-reference the part number with the manufacturer's current datasheet to validate availability and technical parameters before finalizing orders.

Selection Notes

Select this component when a compact, temperature-stable high-pass filter is required for frequencies above 1.79 GHz. The LTCC construction offers a small form factor suitable for space-constrained designs. Consider the 7W power handling rating for applications involving higher signal levels. Verify that the 50 Ohm impedance matches the system requirements and that the SMD package aligns with the PCB layout constraints.

Part Context

This component belongs to the HFCN series of LTCC high-pass filters produced by Mini-Circuits. These filters are designed for RF and microwave applications requiring low insertion loss and high isolation. The series leverages mature LTCC technology to deliver reliable performance in wireless communication systems, test equipment, and industrial measurement devices where size and stability are critical.
