High-Density Shielded Power Inductors Optimize Miniaturized Power Conversion Circuits
Release time：
2026-06-24
Ruiyuan Electronics launches its brand-new Shielded SMD Power Inductors series, tailored to meet the rising demand for miniaturization, low loss and stable current output in modern power conversion equipment. This series integrates advanced shielding magnetic structure and optimized winding design, delivering outstanding electrical performance and ultra-low electromagnetic interference for compact electronic power systems.
Adopting high-permeability low-loss alloy magnetic core, the power inductors effectively cut core loss and suppress temperature rise under continuous heavy load. A full magnetic shielding enclosure restrains magnetic leakage, eliminating cross-interference between adjacent components on dense PCB layouts. Multiple standard inductance specifications cover 0.47μH–47μH, with three mainstream tolerance grades (K=±10%, M=±20%, N=+30%) available to match diverse precision voltage regulation schemes. Standard SMD surface-mount form factor supports carrier tape packaging, perfectly compatible with automated high-speed SMT production lines, shortening assembly cycles and lowering overall manufacturing costs.
This series of shielded power inductors serves as core passive components for DC-DC voltage regulators, battery energy management modules, switching power supplies and signal filtering circuits. The reinforced sealed core structure maintains consistent inductance output under wide temperature range (-40℃~125℃), adapting to rigorous working conditions of automotive electronics, industrial control equipment, AI computing servers, communication base stations and portable consumer devices. The low DCR winding design minimizes power consumption during energy conversion, directly boosting the overall efficiency of power supply systems.
Ruiyuan Electronics supports full personalized customization for this power inductor series. Engineers can adjust target inductance value, tolerance range, physical outline size and packaging format according to unique project design indexes. Combining compact shielding structure, low thermal loss, stable large-current operation and customizable parameters, these power inductors become a reliable core component choice for circuit designers pursuing high efficiency, small size and long service life.
