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. | ||
