Notes:
1. Nominal dimensions for one heat sink of this type.
2. Thermal performance values shown are per pair of heat sinks.
3. Natural convection performance at 50°C heat sink rise above
ambient.
4. Black anodize finish [1.875 in. (47.6 mm) diameter spot
face. Device mounting surface area free of finish].
5. Predrilled heat sinks accept 130 and 139 Series clamp
systems.
** -9 indicates heat sinks drilled for 139 clamp.
