AMP0503H

Product Introduction

Sunlord AMP0503H is an automotive molded SMD power inductor from the AMP series in metric 0503 (5.6×5.2×2.8mm). Ferrite core with metal-alloy material and a closed magnetic circuit gives high current handling and low loss; AEC-Q200 qualified with a -55°C~+150°C operating range and up to 100 V DC withstand, for ADAS, infotainment, LED lighting and BMS power stages.

Core Advantages

• Molded SMD Power Inductors (AMP, Automotive): compact metric 0503 (5.6×5.2×2.8 mm), Isat up to 30 A — molded closed magnetic circuit, AEC-Q200 qualified — high current handling with low loss.
• Low DCR, high current: DCR 2.6mΩ~153mΩ (typ.); saturation current up to 30.0A — high DC-bias performance in a metric body.
• Compliance: Halogen-free, RoHS compliant.
• Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.

Applications

FAQ

Q: Is the AMP series automotive qualified?

A: Yes — AMP inductors are AEC-Q200 qualified with a -55°C~+150°C operating range including self-heating, halogen-free and RoHS compliant.

Q: What does the molded construction give me over a wire-wound part?

A: The molded metal-alloy body forms a closed magnetic circuit: higher saturation current in a smaller footprint, minimal leakage flux and very low buzz noise.
