The Cap-Rack (US Patent 6,058,004) is an assembly of individual chip capacitors, bonded with high temperature epoxy.  A Cap-Rack can be made up of a pair, to as many as eight same size chips - 0603,0805,1005,1206,1210,1808,1812,1825,2221 and 2225 - into one single component providing extended freedom for PCB space utilization.  Footprint dimensions can also vary to further optimize board space usage.  The patented design allows the chip to behave as individual components, not as a single large ceramic mass, and therefore reduces harmful thermal stress during assembly.  Typical applications are in Multi-line designs, Mobile phones, Automotive, Computers, Network Devices and Medical products.
Electrical advantages include reduction in "cross talk", to insignificant levels, by elimination of capacitance coupling between adjacent capacitors; the ability to combine resistors and inductors within the Cap-Rack, as well as mixing and matching capacitance values and dielectrics.
Mechanical advantages include reduced board area; easier to handle; reduced placement cost; reduces components stress and decreased cycle time.  Cap-Rack can also be used with traditional pick and place equipment.
Consult the sales office for High Reliability versions and custom designs, particularly for high voltage applications.

  • P & AW dimensions are dependent on the chips utilized in the array.
  • Cap Arrays require drawings to specify length and width of array and chip size used. Please contact the sales office.
