SMD Aluminium Electrolytic Capacitors with Ultra-Low ESR
High temperature lead-free reflow
The FP Series of +105°C SMD aluminium electrolytic capacitors
from Panasonic delivers Equivalent Series Resistance (ESR) values that rival polymerised organic
semiconductor alternatives.
The ESR value of an FP-Series G-case size is only 60m Ω and an FP-Series F-case size is a maximum of 80m Ω over the capacitor lifetime (2000h at +105°C). This represents a reduction of nearly 50% in comparison with the Panasonic FK-series. These very low ESR values enable a ripple current of 1190mA at 100kHz/+105°C.
Currently Panasonic offers FP Series devices in voltage ranges from 6.3V to 35V and capacitance values ranging from 4.7°F to 1800°F. Further CV values are under development.
A supplementary advantage of the FP-series is the components' ability to withstand higher soldering temperatures for lead-free reflow soldering. Devices up to 6.3mm in diameter can survive peak temperatures of +260°C.

For applications that require high resistance to vibration and shock, diameter 8mm and 10mm parts within the FP-series can also be supplied in an anti-vibration version, with special supportive terminals and a higher bottom plate socket. This design enables capacitors to withstand up to 30G acceleration.
The FP-series complies with all relevant automotive standards and is suitable for automotive, telecommunication and industrial applications.
