Cap-Rack Capacitor Assemblies

• 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.
• Contact our sales team for High Reliability versions and custom designs, particularly for high voltage applications.
• Cap Arrays require drawings to specify length and width of array and chip size used. Please contact our sales team for details.

Knowles Precision Devices produces a wide range of dipped radial leaded capacitors. These are available in rated voltages of 50V up to 6kV. Although our catalog range extends to 6kV, we are able to offer a capability for specials up to 12kV. Our larger case sizes and high voltage versions are particularly in demand, especially for mil/aero and medical power supply applications. Please contact the Sales Office to discuss any special requirements.

• High working voltage - up to 12kVdc
• Large case sizes
• RoHS compliant versions
• Tin-lead plated wire option to reduce tin whiskers (quote suffix A97 for 8111 to 8141 & A31 for 8151, 8161, 8171).
