LFCN-2250D+

Overview

The LFCN-2250D+ is an LTCC low-pass filter designed for RF applications. It operates from DC to 2250 MHz with a 50Ω impedance. The device features a low insertion loss of 0.7 dB and supports DC pass-through capability, providing greater than 100 MOhm isolation to ground. It utilizes the FV1206 surface-mount package style and is rated for an operating temperature range of -55°C to +100°C.

Feature Summary

• Supports DC pass-through input and output
• Provides high isolation to ground exceeding 100 MOhm
• Utilizes LTCC technology for compact surface-mount integration

Applications

• RF signal filtering in communication systems
• Harmonic suppression in transmitter stages
• Signal conditioning in microwave circuits

Procurement Notes

Verify the specific part number suffix against official Mini-Circuits documentation to confirm functional characteristics. Ensure the procurement specification matches the required DC pass-through capability and impedance parameters. Confirm that the component meets the specified temperature ratings for the intended application environment before finalizing orders.

Selection Notes

Select this component when a low-pass filter with DC continuity is required. The D suffix indicates DC pass functionality compared to standard versions. Consider the FV1206 package dimensions for PCB layout constraints. Verify that the 2250 MHz cutoff frequency aligns with the system's spectral requirements.

Part Context

This component belongs to the LFCN series of ceramic filters manufactured by Mini-Circuits. The series includes various low-pass filter models optimized for RF and IF applications. The LFCN-2250D+ specifically addresses needs for broadband filtering with DC connectivity in compact form factors.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Standard LFCN-2250+ lacks DC pass capability; verify if DC continuity is mandatory for the circuit design before considering non-D suffix variants.
