5. Leakage Inductance is for L1 and is measured with L2 shorted.
1. When ordering, please specify termination and packaging codes:
MSD1260-105KLD
Termination: L = RoHS compliant matte tin over nickel over phos
bronze.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (500 parts per full reel).
6. DC current, at which the inductance drops 30ꢀ (typ) 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.This information is for refer-
ence only and does not represent absolute maximum ratings.To predict
temperature rise go to online calculator.
8. Maximum current when applied to one winding that causes a 40°C tem-
perature rise from 25°C ambient.This information is for reference only
and does not represent absolute maximum ratings.To predict tempera-
ture rise go to online calculator.
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter D instead.
9. Electrical specifications at 25°C.
Refer to Doc 639 “Selecting Coupled Inductors for SEPIC Applications.”
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
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.
Coupled Inductor Core and Winding Loss Calculator
This web-based utility allows you to enter frequency, peak-to-peak
(ripple) current, and Irms current to predict temperature rise and overall
losses, including core loss. Go to online calculator.
4. SRF measured using an Agilent/HP 4191A or equivalent.When leads
are connected in parallel, SRF is the same value.
