AMWPH4018S

Product Introduction

Sunlord AMWPH4018S is the metric 4018 (4.0×4.0×1.8mm) member of the AEC-Q200 AMWPH automotive power inductor family. Ferrite plus precision winding with magnetic-glue full shielding achieves high power density with low DCR and strong DC-bias performance, sized for BMS, smart cockpit and ADAS mid-power rails from -55°C to +125°C.

Core Advantages

• High power density: 4018 platform balances 4×4mm footprint with 1.8mm height and up to 5.5A saturation current.
• Low DCR: from 30mΩ typical — less conduction loss in always-on automotive rails.
• Wide 1–100μH range: covers buck, boost and SEPIC filter values in one P/N family.
• Magnetic-glue full shielding: closed magnetic circuit keeps EMI low for ADAS and sensor supply units.
• AEC-Q200 + RoHS: automotive-grade reliability, halogen-free materials for global compliance.

Key Specifications

Cross Reference & Replacement

Cross-reference alternatives: Cyntec (global wire-wound benchmark, same pads), ROHM (100% footprint-compatible AEC-Q200 shielded inductors) and TAI-TECH (Taiwan supply chain option with competitive cost). AMWPH4018S matches their core electricals and shielding.

Applications

FAQ

Q: Is AMWPH4018S pin-compatible with ROHM 4018 inductors?

A: Yes — metric 4018 footprint with 100% pad compatibility, matching DCR/Isat and shielding characteristics.

Q: What current can AMWPH4018S handle?

A: Saturation current 0.5–5.5A depending on inductance value; RMS current 0.5–3A.
