Example
Part Numbering System
≤30 nH measured 1/4” from case at 1 MHz
Case EK 43 g typical
Case EA 76 g typical
Case EB 92 g typical
18 AWG copper wire with 60/40 tin-lead electroplate, 20 amps max
The ripple current capability is set by the maximum permissible internal
core temperature, 125 oC.
The ripple currents in the ratings tables are for 85 oC case temperatures.
For air temperatures without a heatsink use the multipliers Ambient
Temperature, No Heatsink.
Temperature rise from the internal hottest spot, the core, to ambient air is
?T = I 2 (ESR)(θcc + θca)
where θcc is the thermal resistance from core to case and θca from case to
ambient. To calculate maximum ripple capability with the MLS attached to
a heatsink use the maximum core temperature and the values for θcc.
As an illustration, suppose you operate an insulated MLS332M060EB1C
in 65 oC air and attach it to a commercial 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 °C is (125 - 65)/4.5 or 13.3 W. For
an ESR of 31 mΩ, 13.3 W equates to a ripple current of 20.7 A, however, the
wire leads are rated for only 20 A.
