Type MLS 125 ºC Stainless Flatpack,Ultra-Long Life, Aluminum
Specifications
Ripple Current Capability is set by the maximum
permissible internal core temperature, 125 ºC.
Air Cooled. The ripple currents in the ratings tables
are for 85 ºC case temperatures. For air temperatures
without a heatsink use the Ambient Temperature, No
Heatsink multipliers.
Heatsink Cooled. Temperature rise from the internal
hottest spot, the core, to ambient air is:
ΔT = I²(ESR)(Ó¨cc + Ó¨ca)
Outline Drawings
where Ó¨cc is the thermal resistance from core to case
and Ó¨ca from case to ambient. To calculate maximum
ripple capability with the MLP attached to a heatsink
use the maximum core temperature and the values for
Ó¨cc.
As an illustration, suppose you operate an
MLS332M060EB1C in 65 ºC air and attach it to a com-
mercial heatsink with a free-air thermal resistance of
2.7 ºC/W. Use a good thermal grease between the MLS
and the heatsink, and the total thermal resistance is 2.7
+ 1.8 or 4.5 ºC/W. The power which would heat the
core to 125 ºC is (125-65)/4.5 or 13.3 W. For an ESR
of 31 mΩ, 13.3 W equates to a ripple current of 20.7A,
however, the wire leads are rated for only 20 A.
