Panasonic is excited to announce the new FKS Series of Aluminum Electrolytic Capacitors. The FKS Series is a revolutionary product with its impressive small size and powerful performance. In addition, the FKS Series features Panasonics’ advanced foil technology which helps minimizes overall PCB design space. These capacitors deliver the same performance of legacy products, but in a smaller case size. They’re also a Surface Mount product, along with our Aluminum Electrolytic and Film Capacitors types.

Our new FKS Series increases its capacitance performance three times compare to our most popular FK Series in the same case size. FKS comes in a 4x5.8mm can size with the usage of 62% of the space. Along with their higher performance, these capacitors will help replace previously manufactured parts. For example, FKS Capacitors achieves 33µF in comparison to FK devices’ 10µF.

One of the impressive specifications of the FKS Series is the AEC-Q200 qualification and its ability to provide a Capacitor with more stringent quality standards in the industry. Panasonic is able to produce a vibration-proof variant for all FKS parts with specifications in a size of 8mm diameter and larger. A vibration-proof variant can endure shocks up to 30G compare to standard parts that can only endure 10G maximum. The FKS Series datasheet lists all new product information.

Below is the list of FKS Series features, benefits, applications, and industries:


  • Smaller case size
  • Vibration-proof option available
  • AEC-Q200 Qualified
  • RoHS/REACH Compliant


  • One case size smaller than conventional types
  • Can withstand shocks up to 30G
  • Ensures high-quality performance
  • Environmentally friendly


  • DC-to-DC converter
  • Inverter & rectifier circuits


  • Automotive
  • Power suppliers
