High and Medium Power Thick Film Selector


Resistance Value
Safety Margin
K=100/(100-safety)
K: multiplicator on power & energy
example :
safety= 10  ->  K = 1.11  +11%   margin on power & energy
safety= 30  ->  K = 1.43  +43%   margin on power & energy
safety= 50  ->  K = 2       +100% margin on power & energy
