The RH/NH series is a chassis-mount resistor that comes in six sizes, from 5 Watts to 250 Watts when mounted to the specified heat-sink. The molded construction provides complete environmental protection and along with dielectric withstanding voltage as high as 4500 VAC these resistors meet a broad range of applications. The all welded wirewound construction allows the RH/NH to perform in high voltage, high power and high pulse requirements. As optional construction, the RH product is available in the NH non-inductive version. The RH/NH series can also be customized to meet specific application needs, including special terminal and housing modifications, special testing, or many other custom options. The RH/NH series are available in either Pb-Bearing, or Pb-Free (compliant to RoHS directive 2002/95/EC) construction. The RH/NH series is also qualified to military specification Mil-Prf-18546 (type RE), also high-reliability versions are available that are qualified to Mil-Prf-39009 (type RER)
