RB / RBR, HR / 4000, PC Series Radial Lead Precision Wirewound Resistors * * * * * * 0.1 to 0.6 watts Tolerance to .01% 0.1 ohm to 3 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 Miniature printed circuit resistors incorporate an uncommon number of production and design refinements to assure excellent resistance stability, close resistance tolerances, low TCR capabilities and high structural strength. To assure their high quality standards, premium grade selected wire is reverse pi wound with miniumum stress on high temperature epoxy bobbins, permeated with a resilient inner cushion coat, and isolated from the external protection shell by a special dry air chamber. To promote additional resistance stability and accurate initial calibrations all resistors are subjected to an extensive accelerated aging program. Weldable and/or solderable leads (a choice of lead material is available) are firmly anchored and bonded inside the bobbin for maximum structural strength. All resistor markings are impervious to printed circuit board cleaning solvents and lead spacing is sufficiently well controlled for automatic insertion on standard grid boards. Special Screening / Acceptance Test: Special tests can be performed on a 100% or sample basis, to meet individual customer requirements. Some of the available nondestructive tests include: * Vibration * Temperature Coefficient of Resistance * Radiographic Inspection * Short Time Overload * Thermal Shock * Mechanical Shock 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.
