Notes:
6. To order RoHS compliant part, add the suffix “NL” to the part number (i.e. PA0277 becomes
1. The rated current as listed is either the saturation current or the heating current
PA0277NL and PA0277T becomes PA0277NLT).
depending on which value is lower.
2. The saturation current is the current which causes the inductance to drop by 10%
Estimated Temperature Rise:
at the stated ambient temperatures (-40°C, 25°C, 125°C). This current is determined by
.833
placing the component in the specified ambient environment and applying a short
Coreloss (mW) + Copper Loss (mW)
Trise
=
(°C)
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

Coreloss
= K1 * (Fsw (kHz))
* (K2 * dl)

(mW)
increase by approximately 30°C. This current is determined by mounting the component
Copper Loss
= Irms * DCR (mΩ) (mW)
on a PCB with .25” wide, 3 oz. equivalent copper traces, and applying the current to the

device for 30 minutes.

Irms

(Arms)
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
Fsw(kHz)
= switching frequency (kHz)
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
dI
= delta I across the component (A)
taken into account.
5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number,
The temperature of the component (ambient temperature + temperature rise) should
(i.e. PA0277T).
be within the listed operating temperature range.
