TECHNOLOGY
RMW: The resistive element is a wire that is wound on a fiberglass core.
RMF: The resistive element is a metal film resistor consisting of a metal layer deposited over a high-grade ceramic rod.
The terminals are crimped to the resistive body to provide a good mechanical and electrical contact. To ensure a flexible
assembling process, the resistors are offered in various terminals styles, such as long or short, one or two pins. 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, in accordance with IEC 60068-2-45.
