DLFCN-290+

Overview

The DLFCN-290+ is a dual low-pass filter manufactured by Mini-Circuits using LTCC technology. It provides a passband from DC to 290 MHz with a 50 Ohm impedance. The component features an insertion loss of 2 dB and operates in balanced input/output configurations. It is housed in a compact 6-SMD, No Lead package suitable for surface mount applications.

Feature Summary

• Dual low-pass filtering capability utilizing LTCC construction
• Supports balanced input and output signal processing
• Designed for interference mitigation near the 290 MHz center frequency

Applications

• Balanced RF signal conditioning circuits
• Interference mitigation systems
• Signal filtering in communication equipment

Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm electrical tolerances and pinout definitions. Ensure compatibility with the target PCB footprint and reflow soldering profiles specified for LTCC components. Confirm that the 50 Ohm impedance matches the system requirements.

Selection Notes

Select this component when a dual-channel low-pass filter is required for balanced architectures. The LTCC technology offers stability across temperature variations. Consider the 290 MHz cutoff frequency relative to the desired signal bandwidth and the need for rejection of higher-frequency interference.

Part Context

This component belongs to Mini-Circuits' signal conditioning portfolio, specifically within their ceramic filter series. It is designed for high-reliability applications requiring precise frequency response characteristics in a small form factor.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Generic equivalents may not match the LTCC construction or balanced port specifications.
