Advanced Magnetic Solutions for Modern Electronics

Our Magnetic Manufacturing Capabilities

We design and manufacture custom magnetic components for diverse industries — from EVs to consumer electronics. Our facility integrates high-speed winding, vacuum impregnation, and automatic testing for consistent performance. Every design is tuned for low losses, minimal EMI, and thermal stability. Whether you need prototypes or mass production, SB Labs delivers magnetic precision at scale.
Transformers
Our power and isolation transformers are built for consistent performance and long-term stability. Using ferrite and laminated cores, we optimise every design for minimal losses and high dielectric strength. Each unit undergoes temperature rise and Hi-Pot testing to meet BIS and CE standards. Whether for consumer appliances, industrial controls, or EV platforms, our transformers offer tight winding accuracy, insulation reliability, and EMI suppression. We also provide quick prototyping and custom winding configurations to meet voltage, frequency, and form factor requirements.

Choke Coils
Our choke coils are designed to deliver reliable EMI suppression and current stability across power-conversion systems. Built using high-saturation cores, they maintain performance even under voltage spikes or temperature variation. These coils are compact, rugged, and ideal for SMPS, inverters, and motor drives. Each batch is tested for inductance tolerance, resistance, and core integrity, ensuring consistent performance in high-frequency operations. With RoHS-compliant materials and scalable production, we serve clients across consumer electronics, EV systems, and energy applications.
EV Motor Controller (Magnetic Subassemblies)
For EV motor controllers, our precision magnetic subassemblies ensure smooth current flow, thermal efficiency, and reliability under continuous load. Designed to handle high current and frequency, each subassembly integrates high-grade core materials and precision winding. Our testing includes inductance matching, insulation checks, and vibration resistance to meet automotive-grade standards. From concept design to pilot runs, we support OEMs with end-to-end engineering and manufacturing support.

Inductors
We manufacture surface-mount and through-hole inductors that ensure low ESR and high Q-factor across temperature ranges. These inductors are essential for filtering, energy storage, and DC-DC conversion. Using advanced core materials and automated winding systems, we achieve consistent performance in every batch. Ideal for power supplies, audio systems, and embedded electronics, our inductors are tested for mechanical stability and long operational life. Custom shapes, values, and packaging options are available.
