Aluminum Encased Wirewound Resistor

Aluminum Encased Wirewound Resistor

1.Aluminum encased wirewound resistor consists of such resistance element as copper nickel, nickel chrome or manganese copper.
2. The housing of this wirewound resistor is aluminum with hard anodic coating and it uses an alumina or ceramic core.
3. Aluminum encased wirewound resistor adopts 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 terminals and 100W ~ 250 W threaded terminals.

Advantages of Aluminum Encased Wirewound Resistor
1. For aluminum encased wirewound resistor, an aluminum outer case on top of an insulating layer is used.
2. It is able to withstand high temperature and overload.
3. Aluminum encased wirewound resistor comes with high precision, great stability, fine heat dissipation ability and long service life.
4. It is moisture resistant, waterproof and corrosion resistant. Furthermore, it can withstand vibration and harsh environment.

Aluminum encased wirewound resistor is widely used in electronic equipment and electronic complete sets which require high stability. Its applications also include power supplies, transducers, servers and high requirements application under harsh environment.
