Application Notes of Wire wounds (KNP-R)

 When being used in AC circuits, some wirewound structures give inductance ingredients or parasitic

capacity, so they may cause unusual phenomena such as oscillations etc. Quorum deviations of other

components should be carefully taken into account for use.

 Application and Placement: Wirewound resistors use different gauges of wire as resistance elements.

Sometimes the gauge is extremely thin (finer than a strand of human hair) and very susceptible to breakage

in environments containing salts, ash, dust and corrosives. Avoid utilization in such environments.

 Do not install in dusty areas because the accumulation will cause shorts and poor conductance.
