Mounting Capacitors feature low temperature coefficients.

Press Release Summary:

Available in 20 x 40 mils to 127 x 145 mils standard chip sizes with six capacitances ranging from 45 pF to 1000 pF, Mounting Capacitors have 50 VDC to 200 VDC withstanding voltage. Accommodating any FET and MMIC device, units feature gold contacts on both sides. Suitable for applications requiring DC protection, RF bypassing, oscillators and filters, capacitors are developed using MNOS approach and precision photolithography.

Original Press Release:

45 pF to 1000 pF Mounting Capacitors with Very High Q and Class K Qualified for Space

SemiGen, Inc. (, an ISO and ITAR registered RF/Microwave assembly, automated PCB manufacturing, and RF Supply Center, now offers a series of mounting capacitors that can be screen to class K quality requirements for space.

SemiGen’s ideal low loss very high Q mounting capacitors feature low temperature coefficients. With six different capacitances offered from 45 pF to 1000 pF, these capacitors are developed using an MNOS approach and precision photolithography to provide a dependable device. SemiGen’s mounting capacitors are manufactured on dies as thin as 3 mils to limit inductance. These mounting capacitors have a withstanding voltage of at least 50 VDC up to 200 VDC, long-term stability, and gold contacts on the front and back with thermal and mechanical properties that allow the device to be mounted with optimum matching.

Mounting capacitors are ideally suited for applications that require DC protection, RF bypassing, or fixed tuning of amplifiers, oscillators, switches, filters, and multipliers. Standard chip sizes range from 20x40 mils to 127x145 mils, custom designs and thicknesses are available through SemiGen. Design guidelines are virtually limitless and SemiGen can design to accommodate any FET and MMIC device.
