SX Series

The Panasonic EEF-SX Series Specialty Polymer Aluminum Capacitors (SP-Caps) have super low ESR from 4.5mΩ to 9mΩ.  The EEF-SX Series SP-Caps offer lower ESR and higher capacitance at the same case size than conventional products. Other features include a capacitance range from 82µF to 560µF, voltage range from 2VDC to 6.3VDC, and operating temperature range from -40ºC to +105ºC.

Features of The EEF-SX Series

  • Super Low ESR (4.5mΩ to 9mΩ)
  • Capacitance Range 82µF to 560µF
  • Excellent Noise-Absorbing Characteristics
  • High Ripple Current
  • RoHS Directive Compliant
