AS1A4030

Product Introduction

Sunlord AS1A4030 is the high-Isat 4030 member of the 2025 AS1A automotive power inductor platform. With DCR from 14mΩ and saturation current up to 7.9A, it feeds LED headlights, BMS, OBC, high-power DC-DC and ADAS rails from -55°C to +150°C.

Core Advantages

• High Isat up to 7.9A: strong DC-bias margin for high-power automotive stages.
• Ultra-low DCR from 14mΩ: minimal conduction loss in heavy-load rails.
• 1–68μH coverage: power-stage and filter values in one footprint.
• Heat-resistant +150°C: 2025 AS1A platform for high-temperature zones.
• 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 option). AS1A4030 matches their pads and electricals.

Applications

FAQ

Q: What is the saturation current of AS1A4030?

A: 0.9–7.9A depending on inductance value — with DCR from 14mΩ for heavy-load rails.

Q: Does AS1A4030 work in ADAS modules?

A: Yes — magnetic shielding keeps EMI low around sensors, and the -55~+150°C range covers ADAS environments.
