  • Jackcon

Product Features

  • AC high temperature ceramic disc capacitors
  • Dissipation factor of ≤2.5% 
  • Insulation resistance of  10,000 MΩ min at 100Vdc over 1 minute



The Y1 400VAC high temperature ceramic disc capacitor series from Jackcon offers cost effective solution and compact package, while adhering to the majority of internationally recognised safety standards including UL E187963 (see datasheet for the full list). These AC capacitors feature capacitance between 10pF and 4.7nF and dielectric strength of 2600Vac. The available dielectric materials are Y5P or Y5U, dissipation factor of ≤2.5%, with tolerances of either ±10%  (Y5P, Y5U)  or ±20% (Y5U) and TCR  values available either ±10% max (Y5P) or -56% to ±22% (Y5U). The operating temperature of Y1 capacitors is between -40°C and +125°C.
