Through-Hole SMD High Current Power Inductor low DCR high saturation current

Overview
The Through-Hole SMD High-Current Power Inductor from Inductor Supplies bridges the gap between robust through-hole reliability and modern power performance. Designed for applications demanding high current handling, ultra-low DC resistance (DCR), and secure mechanical mounting, this inductor delivers unmatched efficiency and durability in power conversion systems. Ideal for automotive, industrial, and high-reliability environments, it combines the ruggedness of through-hole construction with the precision of advanced magnetic design.

Features

• High Current Capacity: Supports continuous currents up to 50 A and saturation currents up to 65 A, engineered for high-power DC-DC converters, motor drives, and industrial equipment.

• Ultra-Low DCR: Advanced winding techniques minimize DC resistance (as low as 0.0015Ω), reducing conduction losses and maximizing energy efficiency.

• Through-Hole Reliability: Robust through-hole terminals ensure secure PCB mounting, ideal for applications exposed to vibration, shock, or thermal cycling.

• High Saturation Current: Optimized core materials prevent magnetic saturation under extreme loads, maintaining stable inductance and performance.

• Wide Temperature Range: Operates reliably from -55°C to +165°C, with high-temperature-resistant coatings for automotive and industrial use.

• Hybrid Design: Compact form factor compatible with automated assembly processes, blending the strength of through-hole with SMD-like space efficiency.
