What are the key features of XFL4015-471MEB?
- 0.47 µH inductance with ultra-low 8.36 mΩ DC resistance for minimal conduction losses in high-current power stages
- Compact 1616 (4.0 × 4.0 × 1.5 mm) shielded composite-core design reduces EMI and board space simultaneously
- General-purpose power inductor construction supports high-frequency DC-DC converter switching up to multi-megahertz
- Rectangular shielded form factor simplifies automated pick-and-place assembly and reduces stray field coupling to adjacent circuits
What is XFL4015-471MEB used for?
The XFL4015-471MEB is optimized for the output filter inductors of synchronous buck and boost DC-DC converters in smartphones, tablets, SSD storage controllers, and network equipment where board space and efficiency are critical constraints. Its 8.36 mΩ DCR keeps I²R losses low at high output currents, extending battery life in portable devices. The shielded composite core also makes it suitable for noise-sensitive analog and RF power supply rails where stray inductance field emission must be minimized.

Frequently Asked Questions
How does the 8.36 mΩ DCR of the XFL4015-471MEB benefit high-current buck converter designs?
The ultra-low 8.36 mΩ DC resistance of the XFL4015-471MEB minimizes conduction losses (I²R heating) even at high output currents, directly improving converter efficiency. For a 5 A output current, the resistive power loss is only 0.21 W, keeping the inductor cool and allowing the converter to achieve efficiency targets above 90% in compact portable and computing power supply designs.
What switching frequency range is the XFL4015-471MEB suitable for in a synchronous buck converter?
The XFL4015-471MEB with its 0.47 µH inductance is well-suited for synchronous buck converters switching at 1 MHz to 5 MHz, where the inductance value produces acceptable ripple current levels for typical output current ratings. At 2 MHz with a 5 V input and 1.8 V output, the 0.47 µH inductance yields a ripple current of approximately 1.7 A peak-to-peak at a 5 A load, providing a good balance of transient response and ripple.
For a space-constrained SSD or mobile CPU power rail, how does the XFL4015-471MEB's footprint compare to discrete ferrite inductors?
The XFL4015-471MEB in its 1616 case code occupies a 4.0 × 4.0 mm PCB footprint with only 1.5 mm height, making it one of the more compact high-current power inductors available. Compared to larger 5 × 5 mm or 6 × 6 mm ferrite-core alternatives, it saves up to 36% to 56% of board area, which is significant in thin mobile devices or multi-phase SSD controller power stages where every square millimeter of PCB is valuable.
Does the shielded composite core in the XFL4015-471MEB help with EMI compliance in high-frequency power designs?
Yes, the shielded composite core construction of the XFL4015-471MEB significantly reduces stray magnetic field emission compared to unshielded drum-core inductors. This lower EMI radiation helps designs meet CISPR 22 or FCC Part 15 Class B limits in switching frequencies above 1 MHz, reducing the external filtering and shielding cost required to pass electromagnetic compatibility testing in commercial electronics products.
