Frequently Asked Questions
What inductance value and DC resistance does the IHLP4040DZER470M11 offer for DC-DC converter design?
The IHLP4040DZER470M11 provides 47 µH nominal inductance with a DC resistance of only 0.145 Ω, enabling efficient energy storage and minimal conduction loss in buck, boost, and SEPIC DC-DC converters operating in embedded computing and industrial power management applications.
How does the composite core material of IHLP4040DZER470M11 benefit high-current power inductor applications?
The composite core material of the IHLP4040DZER470M11 provides high saturation current handling compared to ferrite cores, maintaining 47 µH inductance at elevated current levels and reducing core loss in switching power supplies and point-of-load regulators with demanding current profiles.
What SMD package size does IHLP4040DZER470M11 use, and how does it fit into compact power supply PCB layouts?
The IHLP4040DZER470M11 uses a 4040 case-size precision moulded SMD package, which occupies a 4.0 mm x 4.0 mm footprint on the PCB, enabling dense power inductor placement in space-constrained DC-DC converter modules, server power supplies, and portable industrial equipment.
When would a designer select IHLP4040DZER470M11 over a ferrite-core inductor for the same 47 µH application?
A designer would choose IHLP4040DZER470M11 over a ferrite-core inductor when the circuit requires higher saturation current without abrupt inductance drop, lower 0.145 Ω DC resistance for reduced heat, and a compact 4040 SMD form factor in high-efficiency DC-DC regulators operating under dynamic load conditions.
