LPH8045 Series, 3-Winding
Coupled Inductors/Transformers

  • Three 1 : 1 windings can be wired in a variety of ways:
    As a 1 : 1, 2 : 1 or 1 : 2 transformer;
    as a 1 : 1 transformer with an aux winding;
    as a gate drive transformer;
    as a SEPIC inductor; etc.
  • Low DCR; excellent current handling
  • 200 Vrms, one minute isolation (hipot) between windings
  • RoHS-compliant. 260°C compatible. Silver-palladium-platinum-glass frit terminations

1 When ordering, please specify packaging code: e.g. LPH8045-223MRC
Packaging:

 

C = 7" machine-ready reel
EIA-481 embossed plastic tape 250 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 C instead.
D = 13" machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
2 Inductance is for each winding, measured at 200 kHz, 0.1 Vrms, 0 Adc
3 DCR is for each winding, measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP 8753ES or equivalent.
5 Isat: DC current at which the inductance drops the specified amount from its value without current. Details
6 Irms: Current through one winding that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
7 Ambient temperature range: −40°C to +85°C with Irms current.
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +125°C (Ambient + temperature rise)
10 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
11 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
