Frequently Asked Questions
What inductance value and DCR does the XAL1010-102MED offer for power converter designs?
The XAL1010-102MED provides a 1 µH nominal inductance with an exceptionally low DC resistance of 1.1 mΩ (0.0011 Ω). This combination enables high-efficiency output filtering in synchronous buck converters operating at switching frequencies from 300 kHz to over 1 MHz with output currents above 30 A.
Which high-current switching applications are best suited to the XAL1010-102MED inductor?
The XAL1010-102MED excels in multi-phase CPU and GPU voltage regulator modules (VRMs), FPGA core supply inductors, and point-of-load DC-DC converters delivering 30 A to 60 A from a 12 V bus to a sub-1 V load rail. Its ultra-low 1.1 mΩ DCR directly reduces I²R conduction losses and improves power conversion efficiency above 95% at peak load.
How does the composite core material of the XAL1010-102MED reduce losses compared to ferrite cores?
The composite core in the XAL1010-102MED exhibits lower core loss density (Pv) at switching frequencies above 500 kHz compared to conventional MnZn ferrite, because composite materials maintain their permeability more linearly under DC bias conditions. This reduces saturation-related inductance droop at high peak currents, keeping the inductance above 0.9 µH even at 80% of rated current, which stabilizes converter loop dynamics.
What PCB footprint does the XAL1010-102MED occupy and how does it compare to smaller case alternatives?
The XAL1010-102MED uses a 4439 case measuring approximately 10.2 × 10.2 mm, which is larger than 3030 or 4040 case alternatives but enables its ultra-low 1.1 mΩ DCR and high saturation current rating. Designs with tight area budgets may use the XAL4040 series in a 4040 case at the cost of higher DCR (typically above 3 mΩ) and lower peak current handling.
