Which Molded Power Inductor is Right for You?

XGL (New!) – Lowest DCR and widest inductance range

  • Lowest DCR
  • Widest inductance range
  • Highest Irms current rating
  • Lowest power losses over wide frequency range (up to 10 MHz)
  • Soft saturation characteristic to withstand high current spikes
  • No thermal-aging issue and perfect for high temperature applications

XEL – High current & high frequency

  • Low inductance values for high-frequency applications (as low as 0.072 µH)
  • Low AC losses at high frequency range (2 to 10 MHz)
  • Soft saturation characteristic to withstand high current spikes
  • Very low DCR
  • No thermal-aging issue and perfect for high temperature applications

XAL – Widest range of sizes & high current

  • Wide range of sizes and inductance values (up to size 1580)
  • High current handling
  • Soft saturation characteristic to withstand high current spikes
  • No thermal-aging issue and perfect for high temperature applications

XFL – Low DCR & lowest profile

  • Lowest profile (as low as 0.5mm high)
  • Low DCR
  • No thermal-aging issue and perfect for high temperature applications

Coilcraft offers four series of high-performance molded power inductors

All are mechanically rugged and magnetically shielded, but each series offers unique performance benefits.

 
Family Unique Performance
XGL Lowest DCR, highest current ratings and features soft saturation
Widest range of inductance values 
Runs cooler than its counterparts
XAL
XEL

The highest current ratings and features soft saturation
XAL – Widest range of sizes 
XEL – Lower inductance values for the highest switching frequencies

XFL Low loss, traditional saturation
Most suitable for lower power applications

The easiest way to choose is by using our Power Inductor Finder and Inductor Analysis & Comparison tool. They'll show performance under your exact operating conditions (current, ripple, temperature, etc.)

Incredible current rating

The soft saturation characteristic provides the XGL, XEL and XAL higher saturation that the XFL, making them ideal for applications requiring high peak current withstanding capability.

AC and DC losses comparison

The XGL and XEL offer the lowest AC loss, making it the best choice for high switch frequency power converters. The XGL features the lowest DCR and the lowest total power losses for the same operating condition.

  Inductance (µH) DCR typ (mOhms) Isat (A) 30%
XGL4020 1 8.2 8.8
XEL4020 1 13.25 9.0
XAL4020 1 13.25 8.7
XFL4020 1 10.8 5.4

The power loss curves shown above are based on real measurements. Please use our Coilcraft Core and Winding Loss Calculator to analyze and compare the performance of these series in the condition of your applications.

Self heating

Along with the lowest DCR, XGL4020 has increased Irms by 60% compared to XEL/XAL. Giving it the ability to run much cooler under the same operating conditions.

For example, at 80°C ambient for the conditions below, the part temperature of the XGL4020 is 30°C less!

IDC = 8 A, 40% ripple = 3.2 A, Freq = 1 MHz
 

  Inductance (µH) DCR typ (mOhms) Irms (A) Part Temp @80°C
XGL4020 1.0 8.2 12 101°C
XEL4020 1.0 13.25 9.6 128°C
XAL4020 1.0 13.25 9.6 131°C

No thermal-aging

In the graph below, core loss remains constant for the Coilcraft inductor compared with dramatic core loss increases caused by thermal aging for other manufacturer's inductors after only 1500 hours at 155°C.
