Hi-Rel Components

We offer a line of fixed attenuators in a high-reliability S-level common platform for space, military, and aerospace designs. The standard parts eliminate the need for costly and time-consuming drawings and specifications meeting the specification and testing requirements of MIL-PRF-55342. 

Features & Benefits

Parts may be ordered 100% tested to Group A with the option to add Group B or Group C.  With our smart part numbering system, companies may designate the level of testing they require simply by indicating Group A, B, & C at the appropriate location in the part number.  Purchasing is made easy with standardized lead times and part number identifiers. 

Various terminal types are available including the high-performance planar flip chip, “W3” triple wrap, “W1” single wrap, and wire bondable gold “WB1” styles. Choose “S” for solder fused terminal plating, “F” style for a RoHS compliant finish using Ag plating, and our “G” version for a wire bondable thick film 99.6% gold finish.  Smiths Interconnect is an AS9100, ISO 9001 and ISO 14001 registered company.
