Coils of Wire— Custom-Built to Your Spec
Coils are essential components in many electronic and electromechanical systems — used for filtering, tuning, power conversion, sensing, and signal coupling. But one size rarely fits all.
We design and manufacture custom coils tailored to your exact application requirements. Whether you need a specific inductance value, wire gauge, core material, or physical form factor — we build it.
What We Can Customize
Parameter Options Inductance Any value within your required tolerance Wire Gauge 12 AWG to 50 AWG — or custom Core Material Ferrite / Iron Powder / Litz / Air Core / Custom Winding Style Single layer / Multi-layer / Toroidal / Bobbin / Custom shape Termination Lead wires / Pins / SMD pads / Custom connectors Coil Form Any custom shape or size — round, rectangular, or custom geometry Coating / Encapsulation Epoxy / Parylene / Varnish / Silicone / Custom Operating Temperature Up to 200°C (depending on materials) Mounting Type Through-hole / Surface mount / Chassis mount / Custom
Common Applications for Custom Coils of wire
Power supply filtering
RF tuning and matching
