LFCN-2500D+

Overview

The LFCN-2500D+ is a low-pass filter manufactured by Mini-Circuits, utilizing LTCC technology. It features a cutoff frequency of 2500 MHz and operates within a DC to 30,500 MHz range. The component has a 50Ω impedance rating and is housed in a compact 4-SMD, No Lead package with dimensions of 3.20mm x 1.60mm.

Feature Summary

• Utilizes LTCC construction for signal filtering
• Provides 50Ω impedance matching
• Designed for surface mount integration

Applications

• RF signal conditioning
• Microwave circuit design
• Signal integrity management

Procurement Notes

Verify the specific datasheet version when sourcing, as specifications may vary between revisions. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Ensure the supplier provides official documentation from Mini-Circuits to validate the LTCC material properties and electrical performance against your design constraints.

Selection Notes

Select this component when a sharp cutoff at 2500 MHz is required in a minimal footprint. The LTCC technology offers stability for high-frequency applications. Consider the 50Ω impedance for standard RF systems. Evaluate the SMD package compatibility with automated assembly processes before finalizing the design.

Part Context

This part belongs to the LFCN series of ceramic low-pass filters from Mini-Circuits. The series is characterized by its use of LTCC materials and surface-mount packaging. These components are designed for RF and microwave applications requiring precise frequency filtering within a small physical profile.

Replacement Considerations

Check for direct substitutes like the LFCN-2600 if a slightly higher cutoff frequency is acceptable. Verify pinout and dimensional compatibility before swapping. Consult Mini-Circuits for updated equivalent parts if the LFCN-2500D+ is discontinued.
