Power Inductors for TI
SolarMagic Power Optimizer

  • Developed for Texas Instruments SolarMagic™ Power Optimizer SM3320 series.
  • JA4487-AL is designed for 30 V to 100 V panels.
    JA4488-AL
    is designed for low voltage panels (<50 V).
  • High current, low DCR, shielded power inductors
  • Recessed board placement for a very low profile design
  • RoHS-compliant. Tin-silver over tin over copper over steel terminations

1 Inductance is measured at 200 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B impedance anaylzer or equivalent
2 Peak primary current drawn at minimum input voltage
3 DCR is with all windings connected in parallel, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Irms: Current that causes the specified temperature rise from 20°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
5 Ambient temperature range: −40°C to +85°C with (40°C) Irms current. Derating curves
6 Storage temperature range: Component: −40°C to +125°C
Tray packaging: −40°C to +80°C
9 Maximum part temperature: +125°C (Ambient + temperature rise)
7 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.
