Specialising in static high-frequency power magnetics with work in fields as diverse as ruggedised products for bulldozers to high-accuracy current transformers for avionics systems. Quantities run from 2 to 2000 pieces. Samples are 1-2 weeks for stocked raw-material product. Typical devices are in the 100mW to 1500W power range. If you have a need that seems like a fit, a detailed verbal description is often enough to determine if it is within our capabilities.
