Product Overview

Aluminum resistor is also called braking resistor, charge resistor, bleeder resistor, or current-limited resistor. It features resistance to shock, high strength power, fast heat dissipation, high stability, and long life.

Construction

An aluminum encased resistor consists 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. Insulation is applied through a high-temperature process.
Embedded in heat-proof cement, it is protected from external mechanical force and dusty environments.

Key Features

Durable, vibration-proof, and excellent heat dissipation.
Low temperature coefficient with resistance varying in direct proportion.
Quick delivery: 5-7 days for standard requirements.
Conforms to RoHS and lead-free standards.
