Procurement Notes

Verify part authenticity through authorized Amphenol distributors. Confirm cryogenic compatibility requirements against specific operational temperatures. Check current supply status as availability may be restricted. Ensure connector gender matches system interface needs.

Selection Notes

Select this model for applications requiring stable attenuation at millikelvin temperatures. Compare power handling capabilities against signal levels. Verify frequency response meets system bandwidth requirements. Consider physical dimensions for space-constrained cryogenic setups.

Part Context

This component belongs to the Amphenol XMA cryogenic attenuator series. These devices are engineered specifically for quantum research and superconducting electronics testing. They provide reliable performance where standard components fail due to thermal contraction or material property changes at low temperatures.

Replacement Considerations

Consider the 2082-6418-20 variant for non-cryogenic applications. Evaluate other XMA models with different attenuation values if signal levels require adjustment. Verify connector type compatibility before substitution.
