Product Overview

Our radial leaded wire wound inductor is a high-performance passive component engineered for professional signal filtering applications, serving industrial electronics manufacturers, circuit design enterprises and electronic component distributors with reliable electromagnetic interference (EMI) suppression and signal optimization solutions. This wire wound inductor for radial lead features a precision-wound copper coil structure combined with a high-quality ferrite core, delivering stable inductance performance, low DC resistance and excellent anti-saturation characteristics. It is RoHS compliant and designed for through-hole mounting, perfectly adapting to the high-density circuit design requirements of industrial-grade electronic equipment, and becoming a core component for improving the signal-to-noise ratio of electronic systems and ensuring stable circuit operation. The radial lead signal filtering inductor covers an inductance range of 1.0uH to 10000uH, meeting the diversified filtering needs of different frequency bands and current levels in industrial applications.

Product Core Design & Performance

Core Structural Design

The product adopts a closed magnetic circuit wire wound structure with a high-purity iron silicon aluminum core, which reduces magnetic leakage loss to less than 0.5% and effectively shield external electromagnetic interference, ensuring no mutual interference with surrounding sensitive components in the circuit. The radial lead is pre-tinned and has a standard pitch design, which is compatible with automatic insertion and welding processes, improving the production efficiency of enterprise customers. The inductor shell uses UL94 V-0 non-flammable insulation material, which enhances the safety and heat resistance of the component.

Key Performance Advantages

Low loss & high efficiency: The high-density winding technology makes the winding filling coefficient reach more than 80%, reducing copper loss by 20%~30% compared with traditional inductors, and the iron loss is significantly reduced under high-frequency working conditions;

Stable inductance performance: The inductance tolerance is controlled within ±5%~±10%, and the long-term drift is less than ±2%, ensuring stable signal filtering effect under different temperature and current conditions;

Strong anti-saturation capacity: It can bear high DC current, and the rated current density is up to 8.0A/mm², which is not easy to saturate under heavy load and maintains stable inductance value;

Excellent heat dissipation: The annular structural design increases the heat dissipation area by about 40%, the working temperature range is -55℃ to 125℃, and the performance is stable without parameter drift in high-temperature industrial environments.
