LFTC-850+

Overview

The LFTC-850+ is a low-pass RF filter manufactured by Mini-Circuits, designed for surface-mount applications. It operates within a frequency range of DC to 850 MHz and features a characteristic impedance of 50 Ohms. The device utilizes LTCC technology housed in the FR933 case style. Key electrical specifications include a cutoff frequency at 1.078 GHz, a maximum insertion loss of 3 dB, and a VSWR of 1.2:1. It provides 20 dB rejection at 1500 MHz and supports a power handling capacity of 16 W. The component is rated for an operating temperature range from -55°C to +100°C.

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure compliance with RoHS standards and correct pin configuration. Confirm that the FR933 package dimensions align with your PCB layout requirements. Cross-reference the datasheet revision date to ensure access to the most current electrical performance graphs and thermal specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-pass filter with a sharp cutoff near 850 MHz is required for 50-Ohm systems. Consider the LTCC construction for reliability in harsh environments. Evaluate the 16 W power rating against system peak power levels. Ensure the SMD footprint matches available board space. Compare insertion loss and VSWR metrics against alternative filters to optimize signal integrity for the specific application bandwidth.

Part Context

Mini-Circuits specializes in radio frequency, intermediate frequency, and microwave signal processing components. The LFTC series represents their line of ceramic low-pass filters.
