*NOTE:
The “NL” suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not necessarily RoHS compliant, but are electrically and mechanically equivalent to NL
versions. If a part number does not have the “NL” suffix, but an RoHS compliant version is required, please contact Pulse for availability.

Notes from Tables
1. The temperature of the component (ambient plus temperature rise) must be within the stated
operating temperature range.
2. The rated current is the current that will cause the temperature
of the part to increase by 40°C with 3.6 volt *
µsec
across the
component and 100LFM of forced air cooling.
3. To determine the inductance of a component at a different operating current, use the graph
below for the appropriate material type.
4. In high volt-µsec applications additional heating may occur due to core losses in the inductor
which may necessitate derating the
current in order to limit the temperature rise of the component. In order to determine the
approximate total losses (or temperature rise) of the component in particular applications, the
following formulas can be used.
Estimated Temperature Rise:
Trise
= AirFlowFactor * K5 * (Coreloss(W) + Copperloss(W))
.833
(C)
Where
AirFlowFactor = 1 (no air flow), 0.53 (100LFM), 0.39 (200LFM), 0.35 (300LFM), 0.30 (400LFM)
CopperLoss
= Irms
2
* DCR_Typical (mΩ) / 1000
DCR_Typical (mW) = .85 * DCR_Max(from table)
CoreLoss
