RoMaks Limited offers a broad range of inductors and magnetic cores for use in power electronics, signal filtering, EMI suppression, and energy storage. With in-stock availability, custom manufacturing capabilities, and expert technical support, we are your go-to partner for magnetic solutions tailored to high-performance electronic systems.

Our components are designed to meet the increasing demands of today's compact, energy-efficient, and high-frequency circuits. Whether you need standard wire-wound inductors, surface-mount coils, or custom ferrite cores — RoMaks provides both standard and bespoke solutions optimized for your applications.

🌀 Our product offering includes:

• Inductors:

  • Wire-wound inductors (SMD and through-hole)

  • Power inductors (shielded, unshielded)

  • Choke coils (common mode, differential)

  • Toroidal inductors

  • Air core and ferrite core inductors

• Magnetic Cores:

  • Ferrite cores (toroid, E, U, RM, PQ, EE, EC, and more)

  • Nanocrystalline and amorphous alloy cores

  • EMI suppression beads and sleeves

  • Custom-shaped magnetic cores for transformers, filters, and converters

All components are manufactured under strict quality standards and conform to RoHS, REACH, and ISO 9001certifications.

🛠️ Custom Development Capabilities:

RoMaks provides engineering and production services for companies requiring custom inductance values, magnetic characteristics, or mechanical dimensions.

• Tailor-made inductors and cores based on electrical requirements, winding specs, and application use cases.

• Custom coil winding with precise turn counts, multi-layer design, and shielding.

• Press mold development for custom ferrite or alloy cores.

• Material options: soft ferrite, iron powder, nanocrystalline, and more.

We support low-MOQ prototyping as well as high-volume production with full documentation and sample testing available upon request.

🚚 Logistics & Stock:

• Large selection of standard inductors and ferrite cores in stock.

• Fast delivery from our Hong Kong warehouse and trusted partner locations.

• Flexible order quantities for both development and mass production stages.

• OEM/ODM branding options available for large orders.

⚙️ Applications:

Our inductors and cores are widely used in:

• Power supplies (SMPS, DC-DC converters)

• Electric vehicle systems

• Industrial motor control

• Signal processing and EMI suppression

• Consumer electronics and IoT

• Telecom and RF modules

We work closely with design engineers, procurement teams, and manufacturers to ensure you receive the exact inductive components your system demands — quickly, reliably, and cost-effectively.
