Coupled Inductor Core and Winding Loss Calculator
1. When ordering, please specify termination and packaging codes:
MSD1260-105KLD
Termination: L = RoHS compliant matte tin over nickel over phos
bronze.
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.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Core material Ferrite
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (500 parts per full reel).
Core and winding loss Go to online calculator
Terminations RoHS compliant matte tin over nickel over phos bronze.
Other terminations available at additional cost.
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.
Weight: 2.8 – 3.2 g
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.
Ambient temperature –40°C to +85°C with Irms current, +85°C to
+125°C with derated current
Storage temperature Component: –40°C to +125°C.
Tape and reel ackaging: –40°C to +80°C
Winding-to-winding and winding-to-core isolation 500 Vrms
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85ꢀ relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Packaging 500/13″ reel; Plastic tape: 24 mm wide, 0.35 mm thick,
16 mm pocket spacing, 6.6 mm pocket depth
PCB washing Tested with pure water or alcohol only. For other
solvents, see Doc787_PCB_Washing.pdf.
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 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. See temperature rise calcu-
lation.
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.
Refer to Doc 639 “Selecting Coupled Inductors for SEPIC Applications.”
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
