SMT POWER INDUCTORS
Wirewound - PD0120NL Series
Notes from Tables
1. The rated current as listed is either the saturation current or the
heating current depending on which value is lower.
2. The saturation current is the current which causes the
inductance to drop by 10% at the stated ambient temperatures
(-40°C, 25°C and 125°C). This current is determined by placing
the component in the specified ambient environment and apply-
ing a short duration pulse current (to eliminate self-heating
effects) to the component.
3. The heating current is the DC current which causes the
temperature of the part to increase by approximately 45°C. This
current is determined by mounting the component on a PCB
with .25" wide, 3 oz. equivalent copper traces, and applying the
current to the device for 30 minutes with no forced air cooling.
4. In high volt*time applications, additional heating in the
component can occur due to losses in the inductor which may
neccessitate 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 losses and core losses should be taken
into account.
5. Optional Tape & Reel packaging can be ordered by adding a
"T" suffix to the part number (i.e. PD0120.102 becomes
PD0120.102T). Pulse complies to industry standard tape and
reel specification EIA481.

6. 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.
7. The temperature of the component (ambient plus temperature
rise) must be within the stated operating temperature range.
