The GL Series was developed specifically to deliver repeatable

and reliable Ultra Broad Band performance up through 40 +

GHz. The GL Series of inductors provide Ultra-Low Insertion

loss, excellent return loss and extreme part to part performance

repeatability. The pyramid shape of the GL Series provides for

maximum inductance in the space available. The GL Series was

developed using a powdered iron core and gold plated

terminations that allow for easy use in hand solder applications.

The combination of Flat Frequency Response with the Ultra-Low

Insertion loss makes this an ideal component for optical data

systems, transimpedance amplifers and test equipment.
