Procurement Notes

Verify the specific manufacturing date code and lot number upon receipt to ensure compliance with project requirements. Confirm that the physical dimensions and mounting interface match the design specifications exactly. Check for any recent product change notices regarding packaging or material composition updates from the manufacturer. Ensure storage conditions align with the component's sensitivity to moisture and mechanical stress before assembly.

Selection Notes

Select this component when high power dissipation is required alongside precise impedance control at frequencies up to 4 GHz. The Aluminum Nitride construction makes it suitable for applications where thermal management is critical. Consider the half flange mount style if board space allows for direct chassis or heatsink attachment. Evaluate the +/-2% tolerance against system requirements for signal integrity and power handling capabilities.

Part Context

This part belongs to the high-frequency/RF resistor category produced by TTM Technologies, Inc. It is specifically designed for attenuator applications in wireless and communication infrastructure. The series emphasizes durability and performance in harsh electrical environments, distinguishing it from standard low-power resistors through its substantial power rating and specialized substrate materials.

Replacement Considerations

Direct substitutes must match the 50 Ohm resistance, 100 W power rating, and DC-4 GHz frequency range. Verify that alternative components utilize similar Aluminum Nitride construction for comparable thermal performance. Ensure the mounting style and physical footprint are compatible with existing PCB layouts or chassis mounts without redesigning the mechanical structure.
