Axial Lead Precision Wirewound Resistors RB / RBR, VA / HR, SP / 7000 Series * * * * * * 0.1 to 1.0 watts Tolerance to .01% 0.1 ohm to 12 meg ohms Approved to M, P, & R levels TCR'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 a unique dry air chamber epoxy shell technique for established reliability parts. A resilient inner coating is used to minimize internal stresses on all parts. All resistors (military and commercial) are carefully monitored during assembly, winding, coating, and stabilization procedures to assure high quality standards. Premium grade selected wire is control- stress wound on special designed bobbins. Established reliability military parts are then burned in for 100 hours at 125C ambient as part MIL-R-93, or equivalent, of group A acceptance testing. Documentation and special tests are available upon customer request to meet your unique requirements. TCR and Temperature Data Style All Styles Resistance Range () Absolute TCR (ppm/C) 0.1 - 0.9 90 1.0 - 9.9 30 10 - 99.9 15 100 - 12M 10 Operating Temperature Range (C) -65 to +145 Special Screening / Acceptance Test: Special tests can be performed on a 100% or sample basis, to meet individual customer requirements. Some of the available non-destructive tests include: * Short Time Overload * Thermal Shock * Mechanical Shock * Vibration * Temperature Coefficient of Resistance * Radiographic Inspection Each of these tests is designed to detect a spectrum of potential resistor defects. Consult the factory for recommendations and a quotation on special screening or acceptance tests to meet your needs.
