Choose Wisely: Which Molded Power Inductor (XEL, XAL, or XFL) is Right for You?

Coilcraft offers three popular styles of high-performance molded power inductors, designated XEL, XAL and XFL Series. They are mechanically rugged and magnetically shielded for use in high density circuits. Each style offers unique performance benefits.

XEL/XAL – High current & high frequency

Wide range of sizes and inductance values (up to size 1580 and 33 µH)
Low inductance values for high-frequency applications (as low as 0.072 µH)
Low AC losses at high frequency range (2 to 10 MHz)
Highest current handling
Soft saturation characteristic to withstand high current spikes
Very low DCR
No thermal aging issue and perfect for high temperature applications

XFL – Lowest losses

Lowest DCR
Lowest profile
Suitable for IoT / Wearables
Offers low inductance values for high frequency applications
No thermal aging issue

The following table demonstrates the differences in these series.

	L nom	DCR typ	Isat (30%)
XEL4020-222	2.2 µH	35.2 mOhms	5.9 A
XAL4020-222	2.2 µH	35.2 mOhms	5.6 A
XFL4020-222	2.2 µH	21.4 mOhms	3.7 A

The following curves, derived from the Coilcraft Core and Winding Loss Calculator, show that the new XEL has lower AC loss compared to the XAL. XFL has the lowest total power loss.

For high switch frequency power converters that are designed to withstand high peak current, XEL is the best choice.
