摘要:
The present electrical resistor package has a naked electrical resistor element which is designed to provide quantitative resistance to electrical current flow, said element is initially encapsulated in a flexible coating, such as silicone wax, which absorbs stresses and is secondarily encapsulated around said flexible coating, in a cushion type moisture barrier coating, such as silicone rubber, to keep moisture away from said element and finally is encapsulated around said moisture barrier coating by a hard protective coating, such as epoxy, to protect the nak ed element from physical and environmental damage.
