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.
