ULP-120+

Overview

The ULP-120+ is a lumped LC low-pass filter designed for surface-mount technology (SMT) applications. It provides a frequency range from DC to 120 MHz with a 50 Ohm impedance. The component utilizes miniature high-Q capacitors to ensure good matching within the passband and high rejection in the stopband. It is housed in a compact top hat package, specifically case style QA2224, measuring 0.25 inches by 0.25 inches. This design supports efficient integration into RF circuits requiring signal filtering.

Feature Summary

• Utilizes miniature high-Q capacitors for superior performance
• Provides high rejection characteristics outside the passband
• Ensures good impedance matching within the operating frequency range

Applications

• RF signal conditioning circuits
• Harmonic suppression in communication systems
• Noise filtering in electronic equipment

Procurement Notes

Verify the specific datasheet version and electrical graphs directly from Mini-Circuits or authorized distributors before finalizing designs. Confirm that the SMT package dimensions align with your PCB layout requirements. Ensure that the thermal and mechanical specifications meet your operational environment standards. Cross-reference part numbers to avoid confusion with similar series components.

Selection Notes

Select this component when a compact, surface-mount solution is required for frequencies up to 120 MHz. Consider its small form factor for space-constrained designs. Evaluate its insertion loss and stopband attenuation against your specific system requirements. Ensure compatibility with standard SMT assembly processes and reflow soldering profiles.
