DCR of 0.18 mΩ
Every part is listed at 0.18 mΩ ±10% DCR, against 0.32–0.47 mΩ for the other WHPBU series. Pick this series when copper loss, rather than inductance range or body size, limits the design.

WHPBU-100710N Power Bead Inductors
WHPBU-100710N is the lowest loss option in the range at about 0.18 milliohm, with 70 amps heating current and inductance from 100 to 470 nanohenries. The taller body buys that headroom, so confirm the height budget before choosing it.

Series overview
Choosing a WHPBU-100710N power bead inductor
WHPBU-100710N power bead inductors are low DCR inductors for high-current phases in multiphase VRMs, one per phase at the output of each power stage. They are also searched as high current power bead inductors or VRM inductors. Values run from 100 nH (WHPBU-100710N-R10L0) to 470 nH (WHPBU-100710N-R47M0), with 0.18 mΩ ±10% DCR and 70 A heating current on every part. For other trade-offs, see the WHPBU-131308N and WHPBU-100705N power beads.
Heating against saturation
Heating current is 70 A for every value. WHPBU-100710N-R10L0 and WHPBU-100710N-R12L0 hold 100 A and 80 A at 100 °C, above that figure, so temperature rise sets their continuous limit.
Tolerance by suffix
L-suffix parts such as WHPBU-100710N-R22L0 are ±15%; M-suffix parts such as WHPBU-100710N-R33M0 and WHPBU-100710N-R47M0 are ±20%. A wider tolerance widens the ripple spread between phases, so include it in worst-case checks.
High values, low saturation
At the high end, WHPBU-100710N-R47M0 is listed at 20 A at 25 °C and 15 A at 100 °C. Values above 220 nH suit fewer, slower phases whose peaks stay well below those figures.

Applications
Applications for WHPBU-100710N power bead inductors
This series fits phases where copper loss dominates the thermal budget.
High-current server VRMs
A server VRM for CPU and memory rails pushes heavy continuous current per phase, which suits the 70 A heating current and 0.18 mΩ DCR. WHPBU-100710N-R10L0 and WHPBU-100710N-R12L0 fit a fast multiphase VRM.
Accelerator cards with large load steps
Accelerator cards draw large, fast load steps. WHPBU-100710N-R10L0, listed at 117 A at 25 °C and 100 A at 100 °C, leaves wide saturation margin above its 70 A heating current.
Network processors and switch ASICs
Core rails on network processors and switch ASICs run hot inside the chassis. A low DCR inductor keeps heating down, and mid values such as WHPBU-100710N-R22L0 balance ripple against saturation margin.

FAQ
Questions on WHPBU-100710N power bead inductors
Supply, which values saturation limits first, and a comparison with WHPBU-131308N.
Why is WHPBU-100710N the lowest loss option?
Its DC resistance is about 0.18 milliohm, roughly half the 0.325 milliohm of the shorter 100705N in the same footprint family. Because copper loss rises with the square of current, halving DC resistance halves the heat at the same phase current, which is significant at tens of amps.
What current can each phase carry?
Heating current is 70 amps, the highest in the range, which caps the continuous RMS at the rated temperature rise. Saturation at 100 degrees spans roughly 15 to 100 amps depending on the inductance value you choose, so read the specific part number rather than the series range.
What is the trade against the shorter body?
Height. The additional winding space that delivers the lower resistance and higher current comes from a taller package. If your design has a height restriction over the power stage, confirm the clearance before selecting this series rather than after the layout is fixed.
Does the wide inductance range help?
It gives flexibility. Spanning 100 to 470 nanohenries means one series can cover designs with different phase counts and switching frequencies. Lower values suit more phases or higher frequency, higher values reduce ripple where the frequency is lower. Derive the value from your ripple budget.
How do I request samples or a quote?
With a complete part number, send the part number, quantity, delivery region and the date you need it. If you are still selecting, send the phase count, per-phase RMS and peak current, switching frequency and the height available over the power stage.
Who manufactures WHPBU-100710N power bead inductors?
VOOHU does, in its own magnetics factory in Mianyang, China. The factory also builds the other WHPBU power bead series and the WHYT molded power inductors, which helps when one board needs both kinds of inductor.
Which WHPBU-100710N values are limited by saturation before heating?
From WHPBU-100710N-R18L0 upward. WHPBU-100710N-R18L0 is listed at 65 A at 100 °C, below the 70 A heating current. The gap grows through WHPBU-100710N-R22L0 at 50 A to WHPBU-100710N-R47M0 at 15 A, so keep transient peaks under the hot figure.
How does WHPBU-100710N compare with WHPBU-131308N?
The WHPBU-131308N page lists 45 A heating current at 0.32 mΩ DCR and hot saturation up to 105 A on WHPBU-131308N-R11K0. WHPBU-100710N offers 70 A heating at 0.18 mΩ for steady high current, while WHPBU-131308N reaches 500 nH.
