temperature rise calculation based on specified Irms
1. When ordering, please specify
termination and testing code:
st512PJD105MLZ
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.
Temperature rise = Winding power loss × 92.5°C
W
Winding power loss = (+
) × DCR in Watts (W)

Equal current in each winding (0.80 A):
Winding power loss = (0.80 + 0.80 ) × 0.30 = 0.384 W
Temperature rise = 0.384 W × 92.5°C
W
= 35.5°C
22
Unequal current (= 1.1 A,
= 0.45 A)
II
L1
L2
:
Winding power loss = (1.1 + 0.45 ) × 0.30 = 0.424 W
Temperature rise = 0.424 W × 92.5°C
W
= 39.2°C
