Power Type Aluminum Housing Fixed Resistors, also known as trapezoidal resistors, braking resistors, discharge resistors, current-limiting resistors, aging resistors, or load resistors, are high-performance components specifically designed for high-power energy absorption and electrical control systems. The products feature a high-strength aluminum alloy housing with heat dissipation grooves on the surface. The internal structure is encapsulated with high-temperature insulating and flame-retardant material. The resistance wire is tightly bonded to the metal housing, providing excellent thermal conductivity and impact resistance. A wide power range (60W to 10000W) is available for individual resistors, ensuring long-term stable operation, making them ideal matching components for power electronic systems.

High Power and High Stability: Capable of withstanding high current surges and prolonged continuous load operation, boasting high power density.

High-Efficiency Heat Dissipation Design: The aluminum alloy casing features heat dissipation grooves, ensuring high heat conduction efficiency and uniform temperature distribution.

Excellent Structural Reliability: The internal potting structure provides moisture resistance, shock resistance, and flame retardancy, ensuring stable operation over extended periods.

Long Lifespan and Low Maintenance: Utilizing high-quality resistance wire and high-temperature materials, its lifespan is more than 1.5 times that of traditional resistors.

Beautiful Appearance: The anodized aluminum casing offers an attractive appearance and excellent corrosion resistance, suitable for various industrial installation environments.
