LFTC-1350+

Overview

The LFTC-1350+ is a low-pass filter manufactured by Mini-Circuits, designed for RF and microwave applications. It features a cutoff frequency of 1350 MHz (DC to 1350 MHz) and operates with a nominal impedance of 50 Ohms. The component utilizes LTCC (Low Temperature Co-fired Ceramic) technology, providing robust signal conditioning capabilities. It is housed in a compact 6-SMD, No Lead surface-mount package, suitable for automated assembly processes. This filter effectively attenuates frequencies above the specified cutoff while maintaining signal integrity within the passband.

Feature Summary

• Utilizes LTCC technology for reliable signal filtering
• Surface mount design for automated integration
• Provides effective attenuation above 1350 MHz cutoff

Applications

• RF signal conditioning circuits
• Microwave communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific suffix (+) indicates lead-free compliance as per Mini-Circuits standards. Confirm the package type matches your PCB footprint requirements. Ensure the operating environment aligns with the component's thermal specifications. Check for any specific handling instructions related to the ceramic construction. Validate that the 50 Ohm impedance matches your system design parameters before procurement.

Selection Notes

Select this component when a sharp cutoff at 1350 MHz is required in a compact form factor. Consider the LTCC construction for stability in varying environmental conditions. Evaluate the surface-mount package against available board space constraints. Compare insertion loss and stopband rejection characteristics against other Mini-Circuits filters if stricter performance metrics are needed. Ensure compatibility with standard SMT assembly processes.

Part Context

The LFTC-1350+ belongs to Mini-Circuits' line of LTCC low-pass filters, which are engineered for high-performance RF applications. These components are part of a broader family offering various cutoff frequencies and impedance values. The series is known for its consistency and reliability in demanding electronic environments. Understanding the broader context helps in identifying compatible components within the same product line for system expansion or replacement needs.

Replacement Considerations

Direct substitutes may include other Mini-Circuits LTCC low-pass filters with similar cutoff frequencies. Verify impedance matching and package dimensions before substitution. Cross-reference electrical specifications such as insertion loss and return loss to ensure equivalent performance. Consult Mini-Circuits documentation for approved alternative part numbers.
