Procurement Notes

Verify the specific suffix 'N' against official Cinch Connectivity Solutions documentation to confirm exact material and plating specifications, as suffixes define critical physical attributes. Confirm current availability status directly with authorized distributors or the manufacturer, as lead times may vary. Ensure environmental compliance requirements align with the non-RoHS status typically associated with this military-grade series before procurement.

Selection Notes

Select this model when a 4dB attenuation value is required within the DC to 12.4 GHz bandwidth. The 2W power handling capability suits moderate power applications. Verify that the SMA interface matches the system interconnect requirements. Consider the MIL-DTL-M3933 qualification if the application demands strict military reliability standards over commercial alternatives.

Part Context

This part belongs to the M3933/25 series of fixed attenuators produced by Midwest Microwave, a brand under Cinch Connectivity Solutions. The series offers various attenuation values and frequency ranges while maintaining consistent military-grade construction. These components are designed for high-performance RF environments where stability and durability are paramount.

Replacement Considerations
