POWER RESISTORS

Low Profile Aluminum Encased Power Resistors

AL

Following market demands for components ~
To deliver power applications in often very confined spaces.


Design engineers can now benefit from Tokenchina's new technologies capable of low profile aluminum encased power AL resistors.


Built to perform in rugged environments, AL resistors are constructed of an alloy metal coil-type resistance element assembled into an aluminum enclosure. Following high-temperature anodization, the enclosure is filled with a special non-flammable cement paste and after hardening, insulation is applied through a high-temperature process.


Token China's flat core winding technology allows for wirewound heat sinkable resistors affording a very low profile, and superior thermal transfer characteristics when compared to conventional aluminum housed wirewound resistors. Supporting a flexible range of applications, the aluminum low profile AL resistor is easy to utilize and install.
