AXIAL LEAD PRECISION WIREWOUND RESISTORS ISO-9001 Registered HR, VA, SP, 7000, 8000 SERIES Non-stress encapsulation 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 terminations are welded to reduce contact noise and produced for critical parameter applications. They are thermal EMF. Extensive accelerated aging programs available for established reliability military and/or both before and after calibration assure precise initial commercial applications requiring state of the art accuracy and high resistance stability. precision and stability. Encapsulation is accomplished by transfer molding Construction features may vary slightly between with special moisture resistant epoxy or by unique commercial and military styles, but both are produced dry air chamber epoxy shell technique for established under the same rigid quality control system required reliability parts. A resilient inner coating is used to by the tightest military specifications. Both are minimize internal stresses on all parts. produced in the same production line using the same highly trained operators required to produce the The established reliability military parts are burned in established reliability product. 100 hours at 125C ambient as part of group A acceptance testing. Documentation and special test Whether military or commercial, all resistors are are available upon customer request to meet your carefully monitored during assembly, winding, coating, unique requirements. and stabilization procedures to assure high quality standards even when their prescribed parameters are non critical. Premium grade selected wire is control stress wound on special designed bobbins.
