1. M Series Power Resistors: This is a range of high power, wirewound resistors from Ohmite that offer excellent performance, stability and wattage ratings. They are available in a wide variety of values and styles, including rods and bars, which can handle from 3 to 1000 watts.
2. FX Series Resistors: This series offers high thermal-convection cooling and low inductance for use in power applications. The FX resistors are available in 25 to 1000 watts, and feature deep side plates that dissipate heat quickly.
3. OZ Series Facial Resistors: This range offers protection from overhangs and crushing loads with its facial construction, with wattages up to 500 watts. The series is available in a wide choice of resistance values, and includes three-terminal models that are solder and plug-in compatible.
4. MT Series Non-Inductive Wirewound Resistors: These resistors feature low inductance values as well as superior and high power ratings. They are available in 10 to 500 watts, with most models being UL and CSA listed.
5. NP Series Finned Aluminium Housed Network Resistors: This series of heat dissipating resistors is designed for high power applications up to 200 watts. They feature a high thermal transfer rate and are available in a wide choice of resistance values.
