SRN Automotive Semi-Shielded Power Inductors Bourns SRN Automotive Semi-Shielded Power Inductors are AEC-Q200 qualified and designed for automotive applications. These wire-wound inductors provide effective magnetic shielding with lower radiation than non-shielded inductors and offer reduced cost to comparably-sized conventional ferrite shield inductors. The SRN components feature a 470nH to 470µH inductance range with a 5.5mΩ to 10.5Ω maximum DC resistance range while operating from -55°C to +125°C.
