IRC AXIAL LEAD PRECISION WIREWOUND RESISTORS HR, VA, SP, son sts expan 7000, 8000 series MIL-R-93 (RB) & MIL-R-39005 (RBR) & COMMERCIAL STYLES Automated, precision windings, protected by silastic undercoat Welded terminations > 0.1 ohm to 12 meg ohms + 0.1 to 1.0 watts Tolerance to +.01% Approved to M, P, & R levels TC's from +2 ppm/C to +6000 ppm/C Meets or exceeds all applicable MIL-R-93 & MIL -R-39005 ratings These ultra precision resistors are designed and selected wire is control stress wound on special produced for critical parameter applications. They designed bobbins. All terminations are welded to are available for established reliability military reduce contact noise and thermal EMF. Extensive and/or commercial applications requiring state of accelerated aging programs both before and after the art precision and stability. calibration assure precise initial accuracy and high resistance stability. Construction features may vary slightly between commercial and military styles, but both are Encapsulation is accomplished by transfer produced under the same rigid quality control molding with special moisture resistant epoxy or system required by the tightest military by unique dry air chamber epoxy shell technique specifications. Both are produced in the same for established reliability parts. A resilient inner production line using the same highly trained coating is used to minimize internal stresses on all operators required to produce the established parts. reliability product. The established reliability military parts are burned Whether military or commercial, all resistors are in 100 hours at 125C ambient as part of group A carefully monitored during assembly, winding, acceptance testing. Documentation and special! coating, and stabilization procedures to assure test are available upon customer request to meet _ high quality standards even when their prescribed your unique requiremenis. parameters are non critical.
