1. When ordering, please specify

termination and packaging codes:

MSD1583-105KED

Termination: E = RoHS compliant matte tin over nickel over phos bronze.

Special order:

Q = RoHS tin-silver-copper (95.5/4/0.5)

or

P = non-RoHS tin-lead (63/37).

Packaging: D = 13

″ machine-ready reel. EIA-481 embossed plastic

tape (300 parts per full reel).

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.

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.

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.

5. 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.

6. Equal current when applied to each winding simultaneously that

causes a 40°C temperature rise from 25°C ambient. This information is

for reference only and does not represent absolute maximum ratings.

To predict temperature rise go to online calculator.

7. Maximum current when applied to one winding that causes a 40°C

temperature rise from 25°C ambient. This information is for reference

only and does not represent absolute maximum ratings. o predict

8. Electrical specifications at 25°C.
