1. The rated current as listed is either the saturation current or the heating current
depending on which value is lower.
2. The nominal DCR tolerance is by design. The nominal DCR is measured from point ⓐ
to point ⓑ, as shown below on the mechanical drawing. The standard part PA1320.
XXXNL has a DCR tolerance of +/-8%. A tighter DCR tolerance (+/-5%) part is available
by changing the NL sux to ANL (i.e. PA1320.121NL becomes PA1320.121ANL).
3. The saturation current is the typical current which causes the inductance to drop by
20% at the stated ambient temperatures (25°C and 100°C). This current is determined
by placing the component in the specified ambient environment and applying a short
duration pulse current (to eliminate self-heating eects) to the component.
4. The heating current is the DC current which causes the part temperature to increase
by approximately 40C. This current is determined by soldering the component on a
typical application PCB, and then applying the current to the device for 30 minutes
with 25LFM of forced air cooling.
5. 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. To determine the approximate total losses (or
temperature rise) for a given application, the coreloss and temperature rise curves can
be used.
6. Optional Tape & Reel packaging can be ordered by adding a “T” sux to the part
number (i.e. PA1320.121NL becomes PA1320.121NLT). Pulse complies to industry standard
tape and reel specification EIA481.
7. The temperature of the component (ambient plus temperature rise) must be within
the stated operating temperature range.
