This product has been  
DISCONTINUED  
PECOS® stands for Porcelain  
Enamel Coating on Steel. It is  
a plate resistor system utiliz-  
ing thick film ruthenium oxide  
on a porcelain coated steel  
substrate. Copper plated silver  
conductors are employed and  
the resistive element is pro-  
tected by a glass passivation  
layer.  
These resistors offer low  
inductance (50nh @1MHz)  
and very high power densities  
(15W/in2). Being PC-board  
mountable, they are economic  
to install and best suited for  
applications under 200V oper-  
ating.
