Edge-wound inductor delivers stable inductance, saturation


Vishay Custom Magnetics IHDM-1008BC-30 IHDM edge-wound, through-hole inductor, with rated current up to 150A for industrial and military applications, features a powdered iron alloy core technology. Device provides stable inductance and saturation over a demanding operating temperature range from -40 °C to +180 °C with low power losses and excellent heat dissipation. The edge-wound coil of the device provides low DCR down to 0.25mΩ, which minimizes losses and improves rated current performance for increased efficiency. Compared to competing ferrite-based solutions, device delivers 30% higher rated current and 30% higher saturation current levels at +125°C. Device’s soft saturation provides a predictable inductance decrease with increasing current, independent of temperature.
