AMWPB7045S

Product Introduction

Sunlord AMWPB7045S is the large-format automotive power inductor of the AEC-Q200 AMWPB series, metric 7045. Ferrite core, precision wire winding and magnetic-glue full shielding form a closed magnetic circuit with excellent DC-bias characteristics, extending the operating range to -55°C to +150°C for LED headlight, BMS, OBC and high-power DC-DC converter stages.

Core Advantages

• Wide -55~+150°C range: 150°C capability fits engine-compartment and high-ambient designs where standard inductors derate.
• Magnetic-glue full shielding: closed magnetic circuit with low leakage flux — clean EMI for ADAS sensors and communication modules.
• Up to 22μH: wide inductance coverage in one footprint simplifies single-platform designs from 1μH to 22μH.
• AEC-Q200 qualified: automotive reliability, halogen-free and RoHS compliant for global programs.
• Mature cross reference: replaces TDK, Vishay and Microgate (麥捷) equivalents pin-to-pin with better lead-time flexibility.

Key Specifications

Cross Reference & Replacement

Cross-reference alternatives: TDK (same-size AEC-Q200 shielded wire-wound, mature Japanese automotive supply), Vishay (equivalent automotive-grade shielded inductors with global coverage) and Microgate (Chinese AEC-Q200 alternative with short lead times). AMWPB7045S is footprint-compatible with all three.

Applications

FAQ

Q: Does AMWPB7045S really work up to +150°C?

A: Yes — the AMWPB 7045 version is specified from -55°C to +150°C including self-temperature rise, ideal for hot engine-compartment zones.

Q: What inductance range does AMWPB7045S cover?

A: 1μH to 22μH at ±20% tolerance across the series, covering the majority of automotive DC-DC output filter values.
