GT The GT Series of ferrite wound inductors for Glass Tube transponder exhibits both high technology and winding skills. Among the many different sizes available, Predan can offer coils with around a thousand turns of 25m diameter selfbonding wire. Both low cost and high production capacity are its most important features. The values and sizes shown in this data sheet are the most commonly ordered by our customers but we can customise your coil. Production of these delicate components is carefully controlled by SPC Quality programs, reinforcing the reliability of the component.
