- Single-function power inductor optimized for output filter and energy storage stages in switching regulators
Applications
The IHLP5050FDER1R0M01 is designed for high-current, high-efficiency DC/DC buck converter output filters in server power supplies, GPU and CPU voltage regulator modules, and industrial point-of-load converters switching at 1MHz to 5MHz. Its ultra-low 2mΩ DCR allows currents of 10A or more with minimal I²R losses, making it a key component in multi-phase power designs for processors and FPGAs. The precision-moulded composite-core construction also suits automotive and telecom power modules where size, efficiency, and thermal performance are critical.

Frequently Asked Questions
How does the 2mΩ DCR of IHLP5050FDER1R0M01 contribute to efficiency in a high-current CPU VRM design?
At 2mΩ DC resistance, the IHLP5050FDER1R0M01 dissipates only 0.2W at 10A continuous output current (P = I² × R = 100 × 0.002), compared to 2W for a similar inductor with 20mΩ DCR. In a multi-phase CPU voltage regulator module with four phases each carrying 10A, the 2mΩ DCR saves 7.2W of total inductor loss versus a 20mΩ alternative, directly improving power supply efficiency by several percentage points.
Why is a composite core used in IHLP5050FDER1R0M01 instead of a ferrite core for high-current power inductors?
The composite core in the IHLP5050FDER1R0M01 provides a soft saturation characteristic, meaning inductance decreases gradually as DC bias current increases rather than dropping sharply as ferrite cores do. This makes composite-core inductors more predictable under peak transient currents in CPU VRMs and server POL converters, where load steps can cause momentary current spikes exceeding the nominal 10A to 20A range without the inductor saturating catastrophically.
At what switching frequency range is the 1µH IHLP5050FDER1R0M01 best suited for a DC/DC buck converter?
The 1µH inductance of IHLP5050FDER1R0M01 is optimized for switching frequencies between 1MHz and 5MHz in synchronous buck converter designs, where the small inductance value allows fast transient response and compact filter designs. At 2MHz with a 12V input and 1V output for a CPU core rail, the inductor ripple current is approximately (12-1)/12 × 1/(1µH × 2MHz) ≈ 0.46A peak-to-peak, providing good ripple attenuation with minimal output capacitance.
How does the precision-moulded 5050 package of IHLP5050FDER1R0M01 affect PCB layout in server and industrial power modules?
The precision-moulded 5050 case (approximately 12.5mm × 12.5mm footprint) provides a self-shielded, low-profile structure that minimizes electromagnetic emissions from high-current switching waveforms, reducing interference with adjacent analog and digital circuitry on the PCB. Its rectangular shape simplifies placement in grid-based multi-phase VRM layouts and allows standard SMT reflow assembly with thermal vias beneath the inductor footprint for improved 85°C or higher ambient temperature operation.
