Planar Chip Inductors

SemiGen manufactures Planar Chip Inductors using either polished quartz or alumina substrates that exhibit a very high dimensional uniformity for bias injection and tuning in microwave amplifier, switch, and multiplier applications.

Planar Chip Inductors

Planar Chip Inductors are offered as individual items or can be purchased in assorted quantities through one of our convenient engineering kits. Inductors are usually available within 2 weeks of order. SemiGen offers the following thin film gold Planar Chip (Spiral) Inductors deposited on polished quartz as standard products. In addition to the standard parts listed below, SemiGen can also fabricate a custom Planar Chip Inductor using your design.
