This leaflet provides a quick reference for a range of heatsinks designed for TO-220 and TO-218 packages. Each entry lists the thermal resistance (°C/W), overall dimensions (height, width, depth) and the corresponding order code.
The document also notes special features such as black anodised finish, fin‑to‑fin assembly options, and top‑surface machining for solid‑state relays and power modules.

The 170‑761 heatsink has a thermal resistance of 5.7 °C/W.
It measures 25.9 mm high, 104.8 mm wide and 150 mm deep.
All heatsinks are black anodised unless a different finish is specified.
Yes, two sections may be assembled fin‑to‑fin for a highly efficient forced‑cooled assembly.
