CHECK these Important Points when you consider RESISTORS: (1) Accuracy: Resistance value within 10% #It tolerance, the accepted commercial limits: Oda# Ohiohms are guaranteed to be within this range: (2) Permanency : Resistance value unchanged by age. The resistance of Ohiohms remaing un" changed over an unusually long period of time; whether in use or in stock: (3) Absence of Noise: Quiet regardless of positior ALL SIZES IN STOCK in circuit: Many static noises are due to FROM 500 OHMS TO faulty resistors.
