TO-220 Power Resistor IRC Advanced Film Division T0220 Series * * * * * TO-220 housing Low inductance (<50nH) Available in 20W or 30W Resistance from 0.01 to 51K High stability film resistance elements 0.01 5% 0541 IRC's TO-220 power film resistors satisfy demanding applications for accurate and stable power resistors housed in the convenient TO-220 case. The resistance element is isolated from the mounting tab by an alumina ceramic layer, providing very low thermal resistance and ensuring high insulation resistance between terminals and tab. The non-inductive design makes these products especially useful in high frequency and high speed pulse applications.
