DRA Automotive Inductors Coiltronics / Eaton DRA Automotive Inductors are shielded inductors featuring high power density, high efficiency, and a storage/operating temperature range of -40°C to +165°C. These inductors provide mechanical secure mounting and offer up to 56A with an inductance range from 0.28µH to 1000µH in five sizes. Coiltronics / Eaton DRA Automotive Inductors are ideal for high shock and vibration environments such as automotive under-the-hood / interior / exterior environments, as well as telematics, noise filtering, filter chokes, and converters (DC-DC, buck, boost, forward, resonant).
