The document provides typical thermal resistance values (°K/W) for the ABL Heatsinks 100 Series across a range of lengths (50 mm to 300 mm). Values are listed for three surface finishes: Black, Black Anodised, and Natural Finish.
Performance tables show that longer heat sinks generally have lower thermal resistance, and that surface finish influences the heat transfer efficiency. The data can be used to select the appropriate heat sink size and finish for a given cooling requirement.
| Thermal resistance (Black finish) at 100 mm length | 1.35 °K/W |
|---|---|
| Thermal resistance (Natural Finish) at 200 mm length | 0.70 °K/W |
The typical thermal resistance is 1.35 °C·W⁻¹.
