| Axial Lead Precision Wirewound Resistors RB/RBR Series * * * * * * 0.1 to 1.0 watts Tolerance to .01% 0.1 ohm to 12 meg ohms 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 The RB/RBR ultra precision resistors are designed and produced for critical parameter applications. They are available for established reliability military and/or commercial applications requiring 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 control 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. All terminations are welded to reduce contact noise and thermal EMF. Extensive accelerated aging programs both before and after calibration 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 established reliability parts. A resilient inner coating is used to minimize internal stresses on all parts. Both military and 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 controlstress wound on special designed bobbins. The established reliability military parts are burned in 100 hours at 125C ambient as part of group A acceptance testing. Documentation and special test are available upon customer request to meet your unique requirements.
