ITG Electronics has released its RL858583 Series Resonant Inductors, a ferrite-based, high-current inductor family designed for resonant power stages used across power electronics, including systems found in electric vehicles (EVs) and other high-efficiency platforms.
In EVs, this includes onboard chargers (OBCs), dc-dc converters, traction inverter auxiliary stages, and wireless charging resonant topologies.
The RL858583 Series provides an inductance range of 6.8 to 22.0 μH with a five percent tolerance. The devices support currents up to 39 A with approximately 30% roll-off in a compact DIP package.
With a rated voltage of 600 Vac and 1000 Vdc and a dielectric strength of up to 4500 Vdc, the inductors are designed for use in high-stress operating environments.
The series features low DCR values from 3.94 to 17.40 mΩ and ACR values from 70 to 200 mΩ, which helps reduce power loss and maintain efficiency across a wide frequency range. Operating temperature spans from minus 55° to plus 130° C, and the parts are RoHS and Halogen-Free compliant.
“Power density and efficiency remain key requirements in modern power conversion systems,” said Martin Kuo, Director of Future at ITG Electronics. “The RL858583 Series combines high current capability, compact dimensions, and configurable inductance options for resonant converters, inverters, and other advanced power applications.”
With a maximum footprint of 21.5 x 21.0 mm and a height of 21.5 mm, the RL858583 Series is suited for space-constrained designs often found in EV power electronics, industrial converters, and other high-density systems. ITG Electronics also offers custom inductance values for applications requiring specific performance characteristics.
