High Frequency MHz Metal Inductor Manufacturer
Quick AnswerA MHz metal inductor uses a metal-composite (metal alloy) core molded into a compact SMD package to deliver stable inductance at switching frequencies from 1 to 100 MHz. The YTMF series covers 0.047–6.8 µH, saturation current 8–120 A and DCR down to 0.22 mΩ, making it the standard choice for AI GPU VRM, NVIDIA H100/B200 power delivery, chip-backside and AI accelerator modules where low profile, low DCR and high self-resonant frequency matter.

Applications
Engineering Resources
As AI accelerators and GPU VRM switch faster to shrink power delivery, the inductor in the converter must keep working at 1 MHz and above. A MHz metal inductor meets this with a metal-composite core and a molded, shielded construction. This guide explains how these inductors differ from ferrite and powder-core parts, the YTMF series specifications, and how to specify them for high-frequency power delivery.
1. What Is a MHz Metal Inductor?
A MHz metal inductor is a surface-mount power inductor built from a soft-magnetic metal alloy powder that is molded directly around the winding into a shielded body. Because there is no air gap and no ceramic material, the core has a flat permeability response well beyond 10 MHz, high saturation flux density and very low radiated EMI. The result is an inductor that keeps its inductance stable while the converter runs at 1–100 MHz switching frequencies.
2. Why MHz Switching Needs a Metal-Composite Core
- Flat permeability to high frequency: metal alloy cores do not roll off like ferrite above ~1 MHz
- Low DCR for high current: molded construction and large flat-wire windings cut copper resistance
- Shielded body: the molded metal shell contains the magnetic field, reducing EMI to surrounding circuits
- High saturation current: soft saturation keeps inductance usable at 8–120 A without abrupt collapse
- Low profile: 1.0–2.5 mm heights fit chip-backside and module placement

Frequently Asked Questions
What is a MHz metal inductor?
A MHz metal inductor is an SMD power inductor with a molded metal-composite core that keeps stable inductance at switching frequencies from 1 to 100 MHz, combining low DCR, high saturation current and a shielded body.
How is a MHz metal inductor different from ferrite?
Ferrite permeability rolls off above roughly 1 MHz and ferrite saturates at lower flux density, while metal-composite cores keep a flat permeability response well beyond 10 MHz with higher saturation current and lower EMI.
What is the YTMF series inductance range?
The YTMF series covers 0.047–6.8 µH with saturation current from 8 to 120 A and DCR down to 0.22 mΩ across four package sizes (YTMF-2012, 2520, 3225, 4030).
Which applications use MHz metal inductors?
AI GPU VRM, NVIDIA H100 and B200 power delivery, chip-backside power, servers and AI accelerator modules where the converter runs at 1–100 MHz.
