RCC Fixed Carbon Composition Resistors Solid carbon resistors designed for high energy dissipation. These small leaded resistors are non inductive and combine high pulse characteristics with excellent stability Power Dissipation 0.25 watts or 0.5 watts Value Range 1R to 22M Tolerance Options 5%, 10%, 20% Maximum Voltage 500 and 700 Vdc Dielectric Strength Peak pulse voltage is 6kv on 0.25 watt size and 10kv on 0.5 watt RoHS Compliant Characteristics Tolerance Combintation of rated resistance and TCR Rated Limiting Rated Isolation Category & preferred Type dissipation element resistance voltage temperature TCR % number Rated resistance at 70C W voltage V range V range range series at -55C at +125C +6.5 / 0 +1 / -5 1R - 1K J (5%) E24 series RCC025 0.25 250 1R - 5M6 +10/ 0 0 / -6 1K1 - 10K 100 K (10%) +13 / 0 0 / -7.5 11K - 100K -55 +125 E12 series +15 / 0 0 / -10 110K - 1M M (20%) RCC050 0.5 350 1R - 22M 500 +20 / 0 0 / -15 1M1 - 22M E6 series Rated Voltage = (Rated dissipation )x(Rated Resistance) (d.c or r.m.s Voltage) Limiting Element Voltage can only be applied to resistors when the resistance is equal to or higher than the critical resistance value. Critical resistance value is the resistance value at which the rated voltage is equal to the limiting element voltage.

Generally, any moisture absorbed during storage will be baked out during the soldering operation. If stored correctly, the resistance shift during soldering will be minimal at less than 3% ARCOL UK Limited, The information contained herein does not form part of a Threemilestone Ind.
