NOTES:
1. To prevent excessive temperature rise, limit ET
OP
to the rated ET
OP
specified. This is not a saturation limit. Temperature rise of inductors
is 40°C MAX at MAX current and rated ET
OP
.
2. A 2:1 nominal inductance swing from no I
DC
to operating I
DC
gives
improved protection against current discontinuities at light loading.
Inductance increases with greater ET
OP
. Reference values occur
at I
DC
and low flux density.
3. LI
2
rating is the ability of the inductor to store energy.
2
4. Design control test voltage is critical. Inductance increases with voltage.
5. RoHS compliant parts are available. Order RoHS compliant parts by adding
the suffix "NL" to the part number (i.e. PE-51506 becomes PE-51506NL).
