Encapsulation enhances the durability of electromagnetic coil windings while adding a level of protection against water, dust, and other contaminants. Encapsulated coils also hold up much better to impacts, vibration, and general rough handling. Because of these numerous performance advantages, custom coil encapsulation is required in many of today’s electronics manufacturing applications. Why Choose Encapsulated […] Read More

Inductor coils are common components that are installed in the majority of today’s electronics devices. Choke inductor coils (sometimes called radiofrequency chokes) are specific types of inductors engineered for signal filtering properties – primarily, passing DC current while filtering out AC current interference. In simple terms, all choke coils are inductors, but not all inductors […] Read More

Self-supported coils, or air-core coils, are special wire winding configurations that forgo the use of a bobbin or core material. Sometimes referred to as freestanding coils, self-supported coils are exactly what they sound like: wire windings that do not require an internal structural support.  The air-core design offers some unique physical and electromechanical properties. In […] Read More

Bobbin wound coils are some of the most common electromagnetic coil components used across a wide range of industries and applications. The bobbin wound configuration features a rigid central core material (generally plastic, glass, special laminated alloys, or phenolic materials) to structurally support the wound coil. The result is a strong, reliable coil winding which […] Read More
