ML612PNDSeries(1278)

Specifications subject to change without notice.

Please check our website for latest information.

1. When ordering, please specify

testing code:

ML612PND105KLZ

Testing: Z = COTS

H = Screening per Coilcraft CP-SA-10001

N = Screening per Coilcraft CP-SA-10004

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. Typical 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. See temperature

rise calculation.

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

temperature rise from 25°C ambient. See temperature rise calculation.

8. 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.
