Figure 7. Heat Sinks with Transverse Fins

Nomenclature for this family of heat sinks is as follows:

MHSxyyy55

where:

x = fin orientation; longitudinal (L) or transverse (T)

yyy = heat sink height (in 100ths of inch)

For example, MHST10055 is a heat sink that is transverse mounted (see Figure 7) for a 4.6 in. x 2.4 in. module

with a heat sink height of 1 in. The “M” prefix represents a heat sink kit with metric hardware.
