150W Four-terminal Ultra-long Creepage Distance Structure with French Blue Baseplate, Non-inductive Molded Power Resistor

Special Design

• The specially - designed molded - package structure gives this product an extra - long creepage distance, meeting the standards of VDE0160 and UL94 - V0.

Technical Features

• When the center temperature of the base plate is ≤85°C, the rated power of a single - resistor structure is 150W.

• Four packaging structures, with a maximum of three resistors packaged.

• Four terminals, with options of insert - type terminals or direct - welding forms.
