CSA Series: Edge-to-Edge Capacitors

csa photoThis classic two-electrode design is the simplest and most widely used. The chip size, shape, and electrical properties may be determined from the dielectric material data and the CSA Selection Chart. Compex is the leader in supplying the LC filter market with custom value parallel plate capacitors. We manufacture tight tolerance, custom filter capacitors to the required size, shape, and value for minimization of post-build tuning requirements. Thicknesses of up to 25+ mils are available utilizing temperature-stable low-loss materials and special terminations to improve the all solder process.

  • Capacitance: 0.04 to 10,000 picofarads and beyond
  • square OR RECTANGLE, LENGTH OR WIDTH .005” and up
