Description
General part information
441 Series
The 441K is a high-performance natural convection Heat Sink made of aluminium with black anodized finish for stud-mount rectifiers and diodes. It is designed for vertical mounting within a power supply enclosure or equipment cabinet without forced airflow available. It will dissipate up to 100W efficiently in natural convection with a maximum 55°C heat sink temperature rise above ambient. When applied in a forced convection environment, it will achieve thermal resistance of 0.18°C/W (sink to ambient) at 1000 LFM. It is supplied with no predrilled device mounting hole pattern.
