NOTES:
1. The rated current as listed is either 85% of 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 15% 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 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 deter-
mined by mounting the component on a PCB with .25” wide, 2 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 core 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, the total copper and core
losses should be taken into account. For approximate value of core
losses, in a given application, use the core loss graph on page 24.
5. Optional Tape & Reel packaging can be ordered by adding a "T"
suffix to the part number (i.e. PA1294.450 becomes PA1294.450T).
Pulse complies to industry standard tape and reel specification EIA481.
6. Meets solderability test per IPC/EIA J-STD-002B using flux type ORL0.
7. To order RoHS compliant part, add the suffix “NL” to the part number
(i.e. PA1294.450 becomes PA1294.450NL and PA1294.450T
becomes PA1294.450NLT).
8. The temperature of the component (ambient plus temperature rise)
must be within the stated operating temperature range.
