Introducing a new technology that brings toroidal inductors one step closer to ideal. Acme's TIGHTpak™ toroids are designed to allow more turns per single layer of windings, allowing the engineer to work with components that exhibit behavior closer to ideal than previously possible.
Ideal inductors are purely inductive with no capacitance. Operation becomes much more complex in inductors with multiple layers of windings because of the effects of parasitic capacitance. EMI concerns, reduced circuit predictability, and a lower SRF (Self Resonant Frequency) all contribute to more complex and usually unattractive circuit behavior. Keeping a toroid's geometry to a single layer minimizes complexity and maximizes design efficiency. Other benefits include reducing the inductor size, lowering the temperature rise by using a larger diameter wire, and increasing inductance.
