Procurement Notes
Verify the specific datasheet revision (e.g., REV. OR) and ECO number (ECO-006054) against official Mini-Circuits documentation before procurement. Ensure the 2.92 mm termination style matches your system interface requirements. Confirm that the UK3042 package dimensions fit your PCB layout constraints. Cross-reference the electrical specifications at 25°C to ensure compliance with your design parameters.
Selection Notes
Select this component when reflectionless performance is critical to maintain signal integrity in the stopband. The wide temperature range makes it suitable for harsh environments. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the physical size of the UK3042 package during board layout planning.
Part Context
This part belongs to the ZXLF series of reflectionless low pass filters from Mini-Circuits. These components are engineered to provide superior stopband rejection compared to traditional designs. The series is widely used in high-performance RF and microwave circuits where minimizing reflected energy is essential for system stability.
Replacement Considerations
Consult Mini-Circuits official substitution guides for verified alternatives. Ensure any replacement maintains the 50 Ohm impedance and compatible termination style.
