Big Power Aluminium Case Wirewound Resistors


Aluminum case wirewound resistors, also named aluminum housed wirewound resistors, features a wire coil wound around a ceramic or fiberglass core, which is then housed in an aluminum casing. This casing provides mechanical protection and acts as a heat sink to dissipate heat generated during operation.

Aluminum case wirewound resistors are a type of resistor that consists of a wire coil wound around a ceramic or fiberglass core, which is then encased in an aluminum housing. These resistors are commonly used in applications where high power handling and stability are required.

The aluminum case provides mechanical protection to the resistor and also acts as a heat sink, dissipating heat generated during operation. This helps in maintaining the temperature within acceptable limits and prevents the resistor from overheating.

Wirewound resistors are known for their high precision and accuracy. The wire coil used in these resistors has a low temperature coefficient of resistance, meaning its resistance remains relatively stable across a wide temperature range. This makes them suitable for applications where temperature changes can affect the performance of the circuit.

Aluminum case wirewound resistors are available in a wide range of resistance values and power ratings to meet different application requirements. They are commonly used in power electronics, industrial control systems, motor drives, power supplies, and various other applications that require high-power handling and stability.

Understanding Wire Wound Resistors: A Comprehensive Guide

图片
Wire wound resistors   are electronic components that play a crucial role in controlling the flow of electric current in a circuit. They are widely used in various applications, ranging from consumer electronics to industrial equipment. In this comprehensive guide, we will delve into the fundamentals of wire wound resistors, including their construction, working principle, advantages, and common applications. 1. Construction Wire wound resistors are made by winding a resistive wire around a non-conductive core. The resistive wire is typically made of materials such as nichrome or a nickel-chromium alloy. The wire is wound in a precise pattern to achieve the desired resistance value. The entire winding is then protected by a coating or encapsulated in a ceramic or vitreous enamel casing for insulation and durability. 2. Working Principle The working principle of wire wound resistors is based on the relationship between the length, cross-sectional area, and resistivity of the wire. When
