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.
The technical profile of the 22µH (220) shielded inductor reflects its efficiency and power-handling capacity with foundational performance data for industrial applications.

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.
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.
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.
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.
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.
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.
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.
High isolation and low noise floor ensure delicate analog physiological sensors measuring microvolt signals are not distorted by power supply switching. Silent operation and mission-critical reliability for medical safety and accuracy.
Provides stable power for solar micro-inverters, battery management systems (BMS), and wireless mesh network gateways. Moisture-proof encapsulation and high thermal mass for long-term stability in unconditioned environments.
