Compact 1.0µH Power Inductor for Conversion

Engineered for efficiency and reliability in modern power management systems, this compact surface mount Inductor delivers stable performance in a wide range of DC-DC conversion applications. With a minimum inductance of 1.0µH—maintained even in parallel winding configuration—and a low-profile form factor measuring just 3.50mm × 3.15mm × 1.37mm (with a maximum installed height of 2.2mm)—it is ideally suited for space-constrained yet power-intensive designs such as server motherboards, telecom power modules, industrial control boards, and automotive electronics. Despite its small footprint, the component handles significant current loads thanks to its robust dual-coil architecture wound with 2UEW-φ0.10 enameled copper wire in a precise 1P×10TS layout, ensuring balanced magnetic flux and reduced core saturation under dynamic operating conditions.

The magnetic core is constructed from H20C ferrite material, selected for its high saturation flux density and low core losses at low to moderate frequencies. This makes the inductor particularly effective in buck, boost, and buck-boost topologies where consistent inductance under DC bias is essential for stable output regulation. Its self-resonant frequency of 100kHz at 0.1V reflects an optimization for low-frequency power applications rather than high-speed signal filtering—a key distinction from Common Mode Choke devices used in data-line EMI suppression. Instead, this component excels in energy storage, ripple current smoothing, and transient response stabilization within switch-mode power supplies (SMPS).

Encapsulated in a durable SOP (Small Outline Package) housing, the inductor supports automated pick-and-place assembly and standard reflow soldering processes. A controlled thickness tolerance of 2.0±0.20mm ensures uniform standoff height across the PCB, minimizing risks such as tombstoning, poor wetting, or mechanical stress during thermal cycling. Operating reliably across the full industrial temperature range of -40℃ to +85℃, it maintains stable electrical characteristics even in harsh environments—making it a dependable choice among critical passive Electronic Components for long-life applications.

Unlike signal-conditioning Inductors or EMI-focused Common Mode Choke units, this device prioritizes energy handling capacity, thermal resilience, and inductance stability over ultra-high-frequency response. Designers often face challenges like audible coil whine, inductor saturation, or thermal runaway in compact power stages; this inductor mitigates such issues through its high-permeability H20C core and symmetrical dual-winding structure, which enhances current-sharing efficiency and reduces magnetic leakage fields that could interfere with nearby sensitive circuits.

When integrating this inductor into PCB layouts, engineers should ensure adequate copper pour for thermal dissipation, avoid placing analog sensors or high-gain amplifiers in close proximity due to potential magnetic coupling, and maintain symmetrical trace routing for both windings to preserve balance—especially in multiphase or interleaved converter designs. Its surface-mount format eliminates the need for through-hole drilling, streamlining manufacturing and improving mechanical robustness in high-vibration settings such as automotive or industrial machinery.

As part of the broader ecosystem of power Inductors, this component represents a smart compromise between size, current capability, and cost-effectiveness. It is not intended for common-mode noise filtering—that role belongs to dedicated Common Mode Choke solutions—but rather serves as a foundational building block in efficient power delivery networks. For design teams developing compact, high-reliability power systems, this inductor offers a proven, scalable solution within the essential portfolio of high-performance Electronic Components required for next-generation electronics.
