Low Profile Aluminum Encased Heat Sinkable Power Resistors (AL)

(AL) Low profile aluminum encased wirewound power resistors boost up high engery applications. Ultra-thin aluminum housed resistance (AL) series, the external type can be divided into (ASQ) ship-shaped aluminum shell resistance, (ASP) low profile aluminum shell resistance, (Asz) trapezoidal aluminum shell resistance three kinds.

Aluminum alloy shell plate core technology, the structure of ultra-thin heat-resistant aluminum encased wirewound resistor (AL) series. Better heat transfer characteristics than conventional wire-wound power resistors, up to 58 types of mold, and suitable for installation and use in different environments.

Direct's flat core winding technology allows for aluminum chassis mount heat sinkable resistor affording a very low profile, and superior thermal transfer characteristics when compared to conventional power wirewound resistors.

(AL) Low Profile Aluminum Encased Series is durable, vibration-proof, dissipates heat well and low temperature coefficient with resistance varying in direct proportion.

The rugged structure, economic price aluminum housed resistor (AL) is easy to utilize and install, and suitable for a wide range applications. Key applications include industrial machinery resistor, load testing resistor, electric power distribution resistors, instruments, and automated control installations.

The (AL) series is RoHS compliant and lead free. For non-standard technical requirements and custom special applications, please contact us to discuss the details.

Construction :
  1. Insulation is applied through a high-temperature process.
  2. An aluminum encased consists of an alloy metal coil-type resistance element assembled into an aluminum enclosure.
  3. After high-temperature anodization, the enclosure is filled with a special non-flammable cement paste and hardening.
  4. Since this component is embedded in the heat-proof cement, it is not affected by external mechanical force, and dusty environments.
