XAL7050 Series High Current
Shielded Power Inductors

  • High inductance – up to 47 µH, for lower values
    see our XAL7030 series
  • High current handling – up to 7.1 A
  • Low DCR – 25 mOhms
  • Soft saturation, ideal for VRM/VRD applications
  • AEC-Q200 Grade 1 (−40°C to +125°C)
  • XAL or XFL: Which is best for your application?
  • RoHS-compliant, halogen free. 260°C compatible. Tin-silver (96.5/3.5) over copper terminations
  • COTS Plus tin-silver-copper and tin-lead terminations available

1 When ordering, please specify termination and packaging codes: e.g. XAL7050-473MEC
  Termination: E = Halogen free component. RoHS compliant tin-silver over copper terminations.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
= non-RoHS tin-lead (63/37).
Packaging: C = 7" machine-ready reel
EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13" machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel)
2 Inductance tested at 1 MHz, 0.1 Vrms, 0 Adc.
3 DCR measured on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP 4395A or equivalent.
5 Isat: DC current at 25°C that causes an inductance drop of 30% (typ) from its value without current.
Temperature derating curves.
6 Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
Irms testing was performed on 0.75 inch wide × 0.25 inch thick copper traces in still air. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, and proximity to other components. Therefore temperature rise should be verified in application conditions.
7 Operating Voltage: 0 – 55 V  More info.
8 Ambient temperature range: −40°C to +125°C with (40°C rise) Irms Derating curves
9 Storage temperature range: Component: −55°C to +165°C
Tape and reel packaging: −55°C to +80°C
10 Maximum part temperature: +165°C (Ambient + temperature rise)
11 Resistance to soldering heat: Max three reflows at +260°C ±5°C for 40 seconds, allowing parts to cool to room temperature between.
12 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.
