LFCN-800D+

Overview

The LFCN-800D+ is a low-pass ceramic filter manufactured by Mini-Circuits, designed for surface-mount applications. It features a cutoff frequency of 990MHz and operates at a system impedance of 50 Ohms. The component utilizes LTCC technology within a compact 4-SMD, no lead package measuring 3.20mm x 1.60mm x 0.94mm. Key electrical specifications include an insertion loss of 1.3dB. The device is RoHS compliant and classified under EAR99.

Feature Summary

• LTCC construction for high reliability in surface-mount environments
• Low insertion loss characteristics for signal integrity
• Compact footprint suitable for space-constrained PCB layouts

Applications

• RF front-end filtering in communication systems
• Harmonic suppression in transmitter stages
• Signal conditioning in microwave circuits

Procurement Notes

Verify the specific suffix designation to ensure compatibility with required termination styles and packaging formats. Confirm that the 50 Ohm impedance matches the target circuit design. Check for updated environmental compliance certifications such as RoHS3 status before finalizing procurement orders to meet regulatory requirements.

Selection Notes

Select this component when a sharp cutoff near 800MHz is required with minimal signal attenuation in the passband. The small SMD package makes it ideal for modern miniaturized electronics. Ensure the operating temperature range meets the -55 C minimum specification for the intended environment.

Part Context

This part belongs to the LFCN series of LTCC low-pass filters from Mini-Circuits. These components are engineered for RF and IF applications up to microwave frequencies. The series offers various cutoff frequencies while maintaining consistent physical dimensions and performance standards across the product line.

Replacement Considerations

Consult official Mini-Circuits documentation for qualified alternate substrate materials or equivalent parts within the LFCN family. Verify pinout and electrical parameters against potential substitutes to ensure functional equivalence.
