Application Notes

Wire-wound Resistors Application Notes:

● 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 com-

ponents should be carefully taken into account for use.

● Application and Placement: Wire wound 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.
