Wire resistor Семейство Wirewound Resistors in Aluminium Housing, 25/50 W
A series of highly stable, aluminium encapsulated, wirewound power resistors for chassis mounting. To be mounted directly onto the cooling surface, preferably with heat conductive paste.
Manufacturing method: The resistance element is wound onto a ceramic trunk with good thermic high-temp. qualities The element is cast in the aluminium housing with a special silicone paste which works well at high temperatures. The casting tool used centres the resistance element in the housing with high precision which give high and secure insulation.
Manufactured in accordance with Mil-R-18546 and is CECC approved.
Power class 50 W and 300 W stocked in a number of special editions of low inductive performance NHS series.
NHS series are crosswound. Технические параметры
