Ohmite 40 Series resistors are the most economical conformal
silicone-ceramic coated resistors offered. These all-welded units
are characterized by their low temperature coefficients and resis-
tance to thermal shock, making them ideal for a wide range of
electrical and electronic applications.
and electrical specifications. Durable but economical 40 Series
resistors exceed industry requirements for quality.
