Driven by the explosion of AI computing power, the rapid upgrading of automotive electronics, and widespread 5G adoption, the electronics industry is undergoing a profound power management revolution. As the core energy-storage and filtering component in DC-DC conversion circuits, the power inductor directly determines system efficiency, stability, and electromagnetic compatibility. Its performance defines the upper boundary of the entire power supply chain.

Why 4.7μH? — The 'Golden Inductance' of Power Design

4.7μH is one of the most iconic inductance nodes in power design. Within DC-DC converters operating at switching frequencies of 1 MHz to 3 MHz, a 4.7μH inductor achieves an ideal balance among output ripple, transient response, and conversion efficiency — earning the reputation of the 'golden inductance'. This product series is compatible with multiple topologies including Buck (step-down), Boost (step-up), and SEPIC, enabling one component to serve multiple circuit configurations. This simplifies BOM management and reduces procurement complexity for engineers.

Core Specifications at a Glance

Typical Application Scenarios

AI Servers & Data Centers

A single AI server consumes 8 to 10× more power inductors than a conventional server, while simultaneously demanding high current capacity, low loss, and high-temperature tolerance. This 4.7μH power inductor series is optimized for GPU VRM, Point-of-Load (PoL) power converters, and multi-phase supply architectures. It effectively handles the high transient di/dt challenges arising from frequent GPU load transitions in AI training and inference scenarios. For full details, visit our Application Solutions page.

New Energy Automotive Electronics

On-board DC-DC converters, BCM (Body Control Modules), LED lighting, and infotainment systems all impose automotive-grade requirements on inductors. Select models in this series meet AEC-Q200 Grade 0 automotive certification, with an operating temperature range of -55°C to +150°C, providing reliable protection in demanding automotive environments.
