LFCW-103+

Overview

The Mini-Circuits LFCW-103+ is an LTCC low-pass filter with a passband from DC to 10 GHz. It features a typical insertion loss of 1.5 dB and provides excellent stopband rejection due to minimized component interaction layout. The device operates at a 50 Ohm impedance, supports surface mount mounting, and has dimensions of 1.60mm x 0.80mm.

Feature Summary

• LTCC construction for compact surface mount integration
• Low insertion loss in the DC to 10 GHz passband
• High stopband suppression through optimized internal layout

Applications

• RF front-end filtering
• Microwave communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet revision and electrical performance graphs against your design requirements. Confirm that the JC0603C-1 package footprint matches your PCB layout guidelines. Ensure compatibility with standard surface mount assembly processes for this ceramic component type.

Selection Notes

Select this component when a low-loss, high-frequency low-pass response is required up to 10 GHz. Consider the small form factor for space-constrained designs. Validate thermal and mechanical stability for the intended operating environment using official reliability data.

Part Context

This part belongs to Mini-Circuits' LFCW series of LTCC filters. These components are designed for RF, IF, and microwave applications ranging from DC to high frequencies. The series emphasizes miniaturization and consistent electrical performance across various frequency bands.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any substitute maintains the same 50 Ohm impedance, package dimensions, and frequency cutoff characteristics to ensure circuit integrity.
