IRC THE RESISTOR PEOPLE AXIAL LEAD PRECISION WIREWOUND MIL-R-93 (RB) & MIL-R-39005 (RBR) COMMERCIAL STYLES @ 0.1 to 1.0 watts e Tolerance to +.01% @ 0.1 ohm to 12 meg e Meets or exceeds ail applicable MIL-R-39005 & MIL-R-93 ratings e Approved to M, P, & R levels @ TCs to +2ppm/C available Automated, precision windings, protected by silastic undercoat Welded terminations These ultra precision resistors are designed and produced for critical parameter applications. They are avail- able for established reliability military and/or commercial applications requir- ing state of the art precision and stability. Construction features may vary slightly between commercial and military styles, but both are produced under the same rigid quality contro! system required by the tightest military specifications. Both are produced in the same production line using the same highly trained operators required to produce the established reliability product. GENERAL SPECIFICATIONS: Whether military or commercial, all resistors are carefully monitored during assembly, winding, coating, and stabilization procedures to assure high quality standards even when their prescribed parameters are non critical. Premium grade selected wire is con- trol stress wound on special design bobbins. All terminations are welded to reduce contact noise and thermal EMF. Extensive accelerated aging programs both before and after calibra- tion assure precise initial accuracy and high resistance stability. Encapsulation is accomplished by transfer molding with special moisture resistant epoxy or by unique dry air chamber epoxy shell technique for es- tablished reliability parts. A resilient inner coating is used to minimize inter- nal stresses on all parts. The established reliability military parts are burned in 100 hours at 125C am- bient as part of group A acceptance testing. Documentation and special tests are available upon customer re- quest to meet your unique require- ments.
