V-FK Series – Low ESR Aluminium Electrolytic Capacitors (SMD Type)


The FK series of +105°C SMD aluminium electrolytic capacitors from Panasonic delivers Excellent Low impedance = ESR Values with wide range line up.

Most Popular and High runner Low ESR SMD Electrolytic series in Panasonic is FK Series. The Impedance value of an FK-Series G-case size is 80mΩ and an FK-Series F-case size is a maximum of 160mΩ over the capacitor lifetime (2000h at +105°C). This represents a reduction of nearly 40-60% in comparison with the Panasonic FC-series. These very low ESR values enable a ripple current of 850mA at 100kHz/+105°C.
