LFCN-900D+

Overview

The LFCN-900D+ is a surface-mount low-pass filter from the Mini-Circuits LFCN series, designed for signal conditioning applications. It operates within a frequency range of 0 Hz to 850 MHz and features a 50 Ohm impedance. The component utilizes an SMD/SMT termination type and is housed in a compact 1206 (3216 metric) package. It exhibits an insertion loss of 1.3 dB and supports board mounting. The device functions reliably across a temperature range of -55°C to +100°C.

Feature Summary

• Surface-mount construction for automated assembly integration
• Low-pass filtering capability up to 850 MHz
• Compact 1206 footprint design

Applications

• RF signal conditioning circuits
• High-frequency communication systems
• Microwave component integration

Procurement Notes

Verify the specific datasheet revision and electrical performance curves directly with Mini-Circuits or authorized distributors before finalizing designs. Confirm that the 1206 package dimensions align with your PCB layout constraints. Ensure thermal management strategies account for the specified operating temperature range of -55°C to +100°C during implementation.

Selection Notes

Select this component when a low-profile, surface-mount solution is required for frequencies up to 850 MHz. The 50 Ohm impedance matches standard RF transmission lines. Consider the 1.3 dB insertion loss and the -55°C to +100°C operational range against system requirements. The 1206 package size offers a balance between performance and board space efficiency for dense layouts.
