ARC3 High Voltage Precision Resistors Designed for applications such as voltage dividers, medical and measuring equipment, electrostatic and current limiting devices where high stability, low TCR and high ohmic values are required. Non Inductive, Thick Film High Voltage to 96 kVdc Low TCR Tolerance as low as 0.1% RoHS Compliant Characteristics Operating temperature: -55C to +225C Tolerance (Code): 0.1% (B), 0.25% (C), 0.5% (D), 1% (F), 2% (G), 5% (J), 10% (K) Temperature Coefficient (Code): 15ppm/C (A), 25ppm/C (E), 50ppm/C (F), 100ppm/C (S), 200ppm/C (L) TCR stated is measure at +25C and +85C. For TCR outside this range, please contact ARCOL Insulation resistance: > 10,000Mohm 500 Volts 25C, 75% relative humidity Dielectric strength: > 1000 Volt 25C, 75% relative humidity Thermal shock: R/R 0.25% max Overload: R/R 0.25% max 1.5 x Pnom, 5 sec (do not exceed 1.5 x V max) Moisture resistance: R/R 0.25% max Load life: R/R 0.5% max 1000 hours at rated load Conformal silicone coating as standard for operation in air. For oil and potted applications, ARCOL would suggest polymide coating. Please contact ARCOL for further details.
