Stable Shielded 220 SMD Power Inductor for Efficient DC-DC Power Converter
High-Efficiency Energy Node: 22µH (220) SMD Shielded Power Inductor
Product Introduction & Strategic Selling Points

The "220" Series SMD Power Inductor, representing a precisely calibrated 22 microhenry inductance value, is a high-performance energy storage and filtering component engineered for modern switching mode power supplies (SMPS) and DC-DC converters. This shielded inductor addresses the challenges of higher power densities and smaller footprints with its robust, magnetically shielded architecture.

Constructed using high-permeability Manganese-Zinc (Mn-Zn) or Nickel-Zinc (Ni-Zn) ferrite core and high-purity copper windings, this inductor handles significant continuous currents with minimal thermal dissipation. The shielded design features internal coil encasement within a secondary ferrite ring, making it ideal for high-density PCB layouts near sensitive components.

Strategic Selling Points
  • Total Magnetic Shielding Architecture: Closed-loop magnetic circuit eliminates radiated EMI for denser component placement
  • Massive Saturation Current Capacity: Maintains 22µH inductance value during significant current surges
  • Ultra-Low DC Resistance (DCR): Optimized winding geometry minimizes resistive losses for higher conversion efficiency
  • Soft Saturation Characteristic: Gradual saturation curve provides safety margin during over-current events
  • Superior Thermal Stability: Rated for wide-ranging industrial environments with high-temperature insulation
  • Precision Automated SMT Design: Flat rectangular top surface for automated vacuum pick-and-place systems
  • Exceptional Signal Integrity: Optimized for switching frequencies from 100kHz to 1.5MHz

Engineering Insight & Parameter Significance

Saturation Current (Isat) is the most vital metric for power system designers. Our audio-grade and industrial-grade cores provide significant safety margin, preventing inductance value drops during current surges.

Low DCR (DC Resistance) is achieved through proprietary winding tension control and high-cross-section copper wire, ensuring minimal energy waste as heat.

Self-Resonant Frequency (SRF) is meticulously controlled to remain well above switching frequencies, maintaining pure inductive behavior for effective high-frequency noise filtering.

Working Temperature Range of -40°C to +125°C provides extreme environmental resilience for automotive and outdoor telecommunications applications.


Product Features & Advanced Manufacturing Advantages
Ferrite-on-Ferrite Shielding Geometry

Unlike traditional open-frame inductors, the "220" series uses a complete ferrite enclosure to contain magnetic flux within the component's housing. This prevents interference injection into surrounding analog signal paths and enables denser PCB layouts.

High-Precision Automated Winding Process

Multi-spindle CNC winding machines monitor wire tension and winding speed in real-time, preventing wire overlapping and insulation abrasion. High-purity oxygen-free copper (OFC) provides lowest possible DC resistance and superior thermal conductivity.

Resin Impregnation and Bonding

Varnish cycle pulls air pockets from internal structure and replaces them with high-grade dielectric resin, making units resistant to corrosive industrial gases and eliminating audible "whining" or "buzzing" sounds.

Automated Optical and Mechanical Verification

High-resolution cameras verify terminal integrity and marking clarity, followed by full electrical sweep of every unit under load. This reduces Total Cost of Ownership (TCO) by eliminating incoming inspection failures and field returns.


Strategic Product Applications across Global Industries
Consumer Electronics and Smart Appliances

Primary choice for power stage of high-definition televisions, gaming consoles, and smart home hubs. Low-profile shielded design fits into cramped product enclosures while keeping EMI emissions within legal limits.

Industrial Automation and Data Center Power

Provides stable energy storage for high-wattage server power units and industrial DC-DC converters. Robust isolation and magnetic shielding ensure clean power in harsh electromagnetic environments.

Medical Device and Laboratory Equipment
