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.
