Bobbin Wound Coils
Bobbin wound coils are manufactured by winding wire onto a rigid, pre-formed spool to ensure consistent shape, structural integrity, and reliable insulation. This construction supports a wide range of core materials and enables termination to pins, offering flexibility for diverse application requirements.
Construction & Capabilities
Able Coil manufactures precision bobbin wound coils engineered to meet your exact specifications. We accommodate both standard and custom bobbin sizes, shapes, and materials to align with your design and performance needs.
For enhanced durability, coils can be encapsulated using epoxy or silicone materials, or protected through thermoplastic injection overmolding. These options provide robust resistance to moisture, corrosion, vibration, and other demanding environmental conditions, ensuring long-term reliability in critical applications.
