Standoff Capacitors
In standoff capacitors, SemiGen offers controlled dielectric thicknesses of +/- 12 microns, < 0.1 micron mounting surface finishes, and outline (L&W) tolerances of < 25 microns. We assure lot-to-lot repeatability and very attractive pricing. RF engineers requiring jumper mounts, bypass and tuning capacitor flexibility will find our wide selection of standoff capacitors convenient and reliable.

Features:
- Series Resonance: (C < 1pf) > 30 GHz (C = 1to 2 pf) > 22 GHz
- Breakdown Voltage: > 100
Applications:
5 micron dielectric border on the front side has “zero burrs” to facilitate edge mounted laser diodes and arrays and prevent solder/epoxy squeeze out. The back side is fully metallized. Edge-to-edge surface planarity on both sides is guaranteed at < 3 microns.
