Procurement Notes

Verify that the specific suffix 'S' corresponds to the screened variant as documented in official datasheets, ensuring compliance with required military standards. Confirm the SMA connector gender configuration matches system requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability of the component.

Selection Notes

Select this model when a precise 12 dB attenuation is required at frequencies up to 18 GHz. Ensure the 2W power rating aligns with the system's signal levels. Consider the extended temperature range if the application involves harsh environmental conditions. Verify impedance matching to maintain signal integrity within the 50 Ohm network.

Part Context

This component belongs to the M3933/25 series of connectorized attenuators produced by Cinch Connectivity Solutions. These devices are designed for high-reliability applications requiring strict adherence to military performance standards.
