CSA SERIES: Edge-to-Edge Chip Capacitors
This classic two-electrode design is the simplest and most widely used. The chip size, shape and electrical properties may be determined and specified from the dielectric material data and the CSA Selection Chart. Case sizes are listed for guidance only. All parts are manufactured directly to customer requirements. All sizes and tolerances can be modified to provide the optimum part for your circuit. Filter applications are readily supported. Thicknesses up to 25 mils and extremely tight tolerances to ±.005pF are available.

CSA Part Number Assembly Example shown specifies COMPEX Series CSA dielectric type C-200, .010" x .010" x .010" max. x .005", gold, 100pF, ± 20% tolerance.

CSA Chip Dimensions
To determine rectangular chip dimensions, calculate the chip area by using the square equivalent. For example, if a 30 mil square chip (900 mil area) yields the desired capacitance and one dimension must not exceed 20 mils, then rectangular chip size would be 20 mil x 45 mil (900 ÷ 20 = 45).

CSM SERIES: Margin Capacitors
Margin caps have the topside electrode withdrawn from the edges in order to increase the distance between electrodes and dramatically decrease the possibilities of shorting when epoxy die-mounting. This style is also widely used for optical recognition-based assembly.

CSM Part Number Assembly Example shown: COMPEX Series CSM dielectric type C-90, .010 x .010 x .006, gold, 2.7pF, ±20% tolerance.
