Techno/Economic Comparison Between Silicon/Cement Coated Wire Wound Resistors And Ceramic Encased Resistors


Traditionally Wire Wound Resistors meant coated resistors of either silicon or vitreous enameled on a Ceramic body which was wound with resistance wire which was welded or soldered to the terminals and these types of resistors were termed as profession …


Comparison Between Silicone Coated & Vitreous Enamelled Wire Wound Resistors


The traditional method of encapsulating resistors through the vitreous enamelled route which was in vogue till about 30 years ago has now been largely replaced with Fire Retardant Silicon/Cement coating. It has now been observed in the market that apar …
