The space-saving attachment die-cast heat sinks for components in TO-3 housings made of AlSi12Cu3 die-cast are available in metallically bright or black coated versions.
The advantage of the attachment variants is the low space requirement, as the dimensions in the footprint of the heatsinks are almost identical to those of the components. The die-cast heat sink thus guarantees efficient cooling in the smallest of spaces.
The die-cast heat sinks enable the coolers to be connected to the TO-3 housing and the unit to be mounted on the board as a unit in one assembly process.
The different performance levels of the die-cast heat sinks are represented by the fin height of the heat sink.
