Aluminum Encased Wirewound Resistor (RHA)

Material
1.Aluminumencased wirewound resistor consists of such resistance element as coppernickel, nickel chrome or manganese copper.
2. The housing of this wirewoundresistor is aluminum with hard anodic coating and it uses an alumina or ceramiccore.
3. Aluminum encased wirewound resistoradopts silicone resin as its encapsulant,cement as its filling material and stainless steel as its end caps.
4. The standard terminals of this resistor are 5W ~ 50W tinned terminalsand 100W ~ 250 W threaded terminals.

Advantages
1. For aluminumencased wirewound resistor, an aluminum outer case on top of an insulatinglayer is used.
2. It is able to withstand hightemperature and overload.
3. Aluminum encased wirewound resistorcomes with high precision, great stability, fine heat dissipation ability andlong service life.
4. It is moisture resistant,waterproof and corrosion resistant. Furthermore, it can withstand vibration andharsh environment.

Application
Aluminum encased wirewoundresistor is widely used in electronic equipment and electronic complete setswhich require high stability. Its applications also include power supplies, transducers, servers andhigh requirements application under harsh environment.
