Component Specifications

Definition
A capacitor array is an integrated electronic component consisting of multiple discrete capacitors arranged in a single package, designed to provide parallel capacitance values for applications such as signal filtering, power supply decoupling, and noise suppression in electronic systems. It optimizes board space and improves signal integrity by reducing parasitic inductance and resistance compared to individual capacitors.
Working Principle
Capacitor arrays operate by storing electrical energy in an electric field between conductive plates separated by a dielectric material. In signal filtering applications, they attenuate unwanted frequency components by providing low impedance paths for high-frequency noise to ground while allowing desired signals to pass, based on their capacitance values and configuration (e.g., in RC or LC filter circuits).
Materials
Materials include ceramic dielectrics (e.g., X7R, C0G), tantalum, or aluminum electrolytes; conductive electrodes of silver, nickel, or copper; and epoxy or ceramic packaging.
Technical Parameters
  • Tolerance ±5% to ±20%
  • Package Type SMD (e.g., 0402, 0603, 0805)
  • Voltage Rating 6.3 V to 100 V
  • Capacitance Range 1 pF to 100 μF
  • Number of Capacitors 2 to 10 per array
  • Temperature Coefficient -55°C to +125°C
Standards
ISO 9001, IEC 60384, MIL-PRF-55681
