COILCRAFT ST466PJD

5030 COUPLED INDUCTORS
Coupled Inductors for Critical Applications
The ST466PJD coupled miniature shielded inductors are
only 3 mm high and 5 mm square. They are ideal for use
in a variety of circuits including flyback, multi-output buck
and SEPIC.
These inductors provide high inductance, high efficiency
and excellent current handling in a rugged, low cost part.
They can also be used as two single inductors connected
in series or parallel or as a common mode choke.

1. When ordering, please specify termination and testing code:
Temperature rise calculation based on specified Irms
ST466PJD105MLZ
Termination:L=RoHS compliant silver-palladium-platinum-glass frit.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Testing:Z =COTS
H=Screening per Coilcraft CPSA-10001
2. Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms,
0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads
are connected in parallel, inductance is the same value. When leads are
connected in series, inductance is four times the value.
3. DCR is for each winding. When leads are connected in parallel, DCR
is half the value. When leads are connected in series, DCR is twice the
value.
4. SRF measured using an Agilent/HP 4191A or equivalent. When leads
are connected in parallel, SRF is the same value.
5. Leakage Inductance is for L1 and is measured with L2 shorted.
6. DC current, at which the inductance drops the specified amount from its
value without current. It is the sum of the current flowing in both windings.
7. Equal current when applied to each winding simultaneously that causes
a 40°C temperature rise from 25°C ambient. See temperature rise
calculation.
8. Maximum current when applied to one winding that causes a 40°C
temperature rise from 25°C ambient. See temperature rise calculation.
9. Electrical specifications at 25°C.
Winding power loss = (IL12 + IL22 ) × DCR in Watts (W)
90°C
Temperature rise = Winding power loss ×
W
Examples for ST466PJB472ML:
Equal current in each winding (1.4 A):
Winding power loss = (1.4 2 + 1.4 2) × 0.111 = 0.435 W
Temperature rise = 0.435 W × 90°C = 39.2°C
W
Unequal current (IL1 = 1.8 A, IL2 = 0.8 A):
Winding power loss = (1.8 2 + 0.8 2) × 0.111 = 0.431 W
90°C = 38.8°C
Temperature rise = 0.431 W ×
W
