- 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. Code Resistance Tolerance B ±0.1% C ±0.25% D ±0.5% F ±1% G ±2% H ±3% J ±5% Version 2010 KNP-R Power Wirewound ResistorsTOKEN Back to 1st Page - Power Precision Wirewound Resistors (KNP-R)
