Product details
Overview
MPL-AL5030-4R7 from Monolithic Power Systems is a low-resistance molded power inductor with 4.7 µH nominal inductance, 33 mΩ typical DCR, 5.3 A rated current (ΔT = 40 K), and 8 A saturation current at both 25°C and 100°C. It operates from –40°C to +155°C and is optimized for high-current, high-frequency DC-DC converters in FPGA and POL applications.
For engineers reviewing the MPL-AL5030-4R7 datasheet, MPL-AL5030-4R7 pinout (though non-pin device), MPL-AL5030-4R7 application in high-current SMPS, or MPL-AL5030-4R7 equivalent for low-DCR molded inductors, this page delivers verified electrical specs, thermal behavior context, package dimensions, and real-world selection guidance.
Technical Context
This molded inductor uses composite powder core technology enabling soft saturation behavior and stable inductance over temperature. Its 5.5 mm × 5.3 mm × 2.9 mm footprint supports high-density PCB layouts while maintaining low AC losses up to 22 MHz self-resonant frequency.
Designed for continuous operation under high ripple current, it delivers consistent performance across –40°C to +155°C ambient, with thermal rise dependent on PCB copper area (35 µm, 30×50 mm single-layer reference) and layout proximity-critical for battery-powered and embedded computing power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Inductance | 4.7 µH ±20% @ 100 kHz, 100 mA - ensures stable energy storage in 500 kHz–2 MHz buck converters |
| DC Resistance | 33 mΩ typ / 36.5 mΩ max - minimizes conduction loss and thermal rise in high-current paths |
| Rated Current | 5.3 A typ (ΔT = 40 K) - defines maximum continuous DC current before thermal derating on standard PCB |
| Saturation Current | 8 A typ @ 25°C & 100°C (L drop ≤30%) - supports peak transient loads without abrupt inductance collapse |
| Self-Resonant Frequency | 22 MHz typ - enables use in high-frequency switching topologies without parasitic impedance dominance |
| Operating Temperature | –40°C to +155°C (including self-heating) - suitable for under-hood automotive modules and industrial edge controllers |
Pinout & Package
Package: Molded SMD, 5.5 mm × 5.3 mm × 2.9 mm (L×W×H); land pattern per MPS Rev. 1.1 drawing; no electrical pins - two-terminal device with top-marked dot indicating start of winding.

FAQ
What is the recommended PCB land pattern for MPL-AL5030-4R7?
The official land pattern is specified in the MPS Rev. 1.1 datasheet: 4.7 mm × 2.0 mm pads with 2.0 mm center-to-center spacing and 0.3 mm solder mask opening. Use thermal vias under pads for enhanced heat dissipation in high-current designs.
Does MPL-AL5030-4R7 support AEC-Q200 qualification?
No-MPL-AL5030-4R7 is not AEC-Q200 qualified. It meets industrial-grade reliability standards and operates up to +155°C, but automotive applications require formal AEC-Q200 testing and documentation not provided for this part.
How does temperature affect saturation current in practice?
Saturation current remains stable at 8 A from 25°C to 100°C ambient due to the composite core's low thermal coefficient. However, self-heating above 100°C may reduce effective ISAT; derating curves in the datasheet show <5% loss at 130°C case temperature.
Can MPL-AL5030-4R7 be used in reverse polarity configurations?
Yes-its symmetric construction allows either terminal to serve as input or output. However, the dot-marked terminal should be used as the switch-node connection in buck converters to minimize EMI loop area and improve noise immunity.
Is lead-free reflow compatible with this inductor?
Yes-MPL-AL5030-4R7 supports standard lead-free reflow profiles (JEDEC J-STD-020, peak 260°C). The molded epoxy withstands multiple reflow cycles without delamination or parameter shift when prebaked per MPS guidelines.
What is the typical core loss at 1 MHz and 2 A RMS?
Per MPS typical performance curves, core loss is ~85 mW at 1 MHz and 2 A RMS. Total loss (core + copper) is ~220 mW, resulting in <15 K temperature rise on the 30×50 mm reference PCB-well within the 40 K ΔT limit.
Does the "4R7" marking indicate inductance value?
Yes-"4R7" is the industry-standard EIA code meaning 4.7 µH (R = decimal point). The dot adjacent to "4R7" marks the start of winding, confirming polarity orientation for layout-critical applications.
