1. Temperature rise is 55°C in typical buck or boost circuits operating
at 300kHz with the rated Idc current and reference ET applied to the
inductor.
2. Total loss in the inductor is 1.8W for 55°C temperature rise above
ambient.
3. In high volt-time applications, additional heating in the component
can 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) for a given application, both copper and core
losses should be taken into account.
Estimated Temperature Rise:

4. Optional Tape & Reel packaging can be ordered by adding a "T"
suffix to the part number (i.e. P0595NL becomes P0595NLT). Pulse
complies to industry standard tape and reel specification EIA481.
5. 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.
6. The temperature of the component (ambient plus temperature rise)
must be within the stated operating temperature range.
