AS1A5020

Product Introduction

Sunlord AS1A5020 is the 5020 member of the 2025 AS1A automotive power inductor platform. Closed magnetic circuit, magnetic shielding and AEC-Q200 qualification deliver 0.47–47μH with Isat up to 9A for LED headlights, BMS, OBC, DC-DC and ADAS rails up to +150°C.

Core Advantages

• Isat up to 9A: strong current capability for mid/high-power automotive stages.
• Low DCR from 12mΩ: high efficiency in heavy-load rails.
• 0.47–47μH coverage: wide filter range in one footprint.
• Heat-resistant +150°C: 2025 AS1A platform for high-temperature environments.
• AEC-Q200 qualified: magnetic shielding, halogen-free, RoHS compliant.

Key Specifications

Cross Reference & Replacement

Cross-reference alternatives: TDK (same-size AEC-Q200 shielded wire-wound), Murata (stable global supply) and Fenghua Advanced (short lead-time alternative). AS1A5020 matches their pads and key electricals.
