IRC PRECISION WIREWOUND PRINTED CIRCUIT BOARD Terminations & RADIAL LEAD RESISTOR Wire terminations made at top of resistor -Protects joints from solder bath PC, HR, 4000 series Sanaa sink providing additional termination : protection Insulated stress relieved windings MIL-R-93 (RB) & MIL-R-39005 (RBR) Custom designs & COMMERCIAL STYLES available Optional lead materials Different lead spacing furnished on request + 0.100 to 0.600 watts - Tolerance to 0.01% (25C) - Non-inductive windings available - TC'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 To promote additional resistance stability and uncommon number of production and design accurate initial calibrations all resistors are refinements to assure excellent resistance subjected to an extensive accelerated aging stability, close resistance tolerances, low TCR program. Weldable and/or solderable leads (a capabilities and high structural strength. To assure choice of lead material is available) are firmly their high quality standards, premium grade anchored and bonded inside the bobbin for selected wire is reverse pi wound with minimum maximum structural strength. All resistor markings stress on high temperature epoxy bobbins, are impervious to printed circuit board cleaning permeated with a resilient inner cushion coat, and solvents and lead spacing is sufficiently well isolated from the external protective shell controlled for automatic insertion on standard grid by a special dry air chamber. 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 non-destructive test include: -Short Time Overload -Temperature Coefficient of Resistance -Thermal Shock -Radiographic Inspection Each of these tests is designed to detect a spectrum of potential resistor defects. Consult the factory for recomendations and a quotation on special screening or acceptance tests to meet your needs. 4060/PC8 0.250 4061 7 - : 0.250 RBR81 0.100 0.200 ratings may be applied at 125C provided 175C max. operation temperature is permissible. **Available as High Reliability styles with complete documentation.
