Qualified to AEC-Q200 Grade 3 (-40 to +85°C) and called the RFC0807BV series, they are 8.8mm in diameter, 7.5mm tall and have radial lead length options between 3.6 and 25mm.
The inductors are “ideal for high-voltage and high-current battery management systems, as well as universal non-isolated off-line ac-dc power supplies for industrial and automotive applications”, according to the company.
The high voltage rating comes from a change in wire insulation compared with the similar RFC0807B family.
19 inductance values are available, from 39μH at 25°C (240mΩ max, 1Arms for 20°C rise, 11MHz self-resonant) to 1.2mH (4.1Ω, 250mArms, 1.7MHz). See below for the complete list.
Potential non-automotive applications include, said Coilcraft: grid infrastructure, smart meters, power monitors, residential circuit breakers, building automation, and home appliances.
