100W to 500W Wire-wound Resistor
[High Power Type Metal Clad Wire-wound Resistor] Cement Sealed Type
A non-combustible heat-resistant cement-sealed wire-wound resistor with excellent short-time overload characteristics.
The outer shape is thinner than the RH series, and various characteristics are improved compared to the IRH series.
It is possible to respond to a significantly shorter delivery time than the conventional IRH series.
Features
