Construction
SBR: The resistive element is a wire that is wound on a high grade porcelain rod. The terminals have fully welded construction to provide a good mechanical and electrical contact. To ensure a flexible assembling process, the resistors are offered in radial terminals styles. The resistor body and lead ends are housed within a rectangular ceramic case which is non-flammable will not melt even at high overloads and is resistant to most commonly used cleaning solvents.
Electrical Characteristics
DERATING
The power that the resistor can dissipate depends on the operating temperature
