ULP-83+

Overview

The ULP-83+ is a lumped LC low-pass filter manufactured by Mini-Circuits, designed for radio frequency applications. It provides a passband from DC to 83 MHz with a nominal system impedance of 50 ohms. The component utilizes surface mount technology (SMT) and is housed in a compact top hat package measuring approximately 0.25 inches by 0.25 inches. Typical insertion loss within the passband ranges from 1.0 dB at DC to approximately 7.41 dB at higher frequencies near the cutoff point.

Feature Summary

• Lumped LC architecture for effective signal conditioning
• Surface mount construction for automated assembly
• Shielded top hat enclosure design

Applications

• RF signal path filtering
• Harmonic suppression
• Signal conditioning in communication systems

Procurement Notes

Verify the specific datasheet revision and performance graphs directly from Mini-Circuits or authorized distributors before finalizing designs. Confirm that the SMT termination style matches your PCB footprint requirements. Ensure compliance with RoHS and REACH standards if required by your manufacturing specifications.

Selection Notes

Select this component when a sharp cutoff below 100 MHz is required in a small form factor. The 50-ohm impedance rating ensures compatibility with standard RF transmission lines. Consider the physical dimensions of the top hat package to ensure adequate clearance on the circuit board layout.

Part Context

This part belongs to the ULP series of lumped element filters from Mini-Circuits. These components are engineered for cost-effective integration into RF circuits where discrete LC filtering is preferred over distributed line structures. The series offers various cutoff frequencies to suit different bandwidth needs.

Replacement Considerations

Consult official substitution guides for equivalent models with similar cutoff frequencies and impedance ratings. Verify mechanical compatibility and electrical performance curves before swapping components.
