0805CS Automotive Wirewound Ceramic Inductors Coilcraft 0805CS Automotive Wirewound Ceramic Inductors provide exceptionally high Q compared to non-wirewound inductors, especially at high frequencies. The unshielded components feature a ceramic construction for the highest possible self-resonance (as high as 12.2GHz). The Coilcraft 0805CS Wirewound Ceramic Inductors are AEC-Q200 Grade 1 (-40°C to +125°C) qualified.
