WHITE PAPER
325F 325F-CAPACITOR General The 325F product belongs to Nesscap’s Mid-Size product range and has been newly introduced to the market. Nesscap’s Mid-Size product range has a proven track record of performing very well in extreme and harsh environments. With Nesscap’s proprietary electrode material and the special designed 2x2 connecting pins the 325F capacitor offers an ultra-low internal resistance (ESR). This allows a narrow banded dispersion of capacitance (C) and ESR which is evident from its homogeneous aging behavior. With its excellent performing DC life time and high cycle life of several hundred thousand cycles, this product offers multiple options for use in various voltage sensitive applications.
Features Highly efficient rugged component Coulombic efficiency is greater than 99% Mechanically robust Technology in use many years under extreme conditions and all weather operations Solderable pins for mechanically robustness against shock & vibrations (& lower contact resistance) Ultra-Low equivalent series resistance Specific electrode technology and 2x2 contact methods enables lowest resistance Wide Temperature Range Very good temperature performance down to -40°C and up to +85°C Monitoring of SOC & SOH Condition Energy stored in a capacitor is a function only of capacitance and voltage Open-circuit voltage measurement defines state of charge Possible state of health calculation due to slow change in capacitance and equivalent series resistance over time Long Operational Life Offers >500k cycles (nominal voltage down to half voltage) Millions of this type of product is in the field in cycling- and DC-applications Extends Battery Life
Applications Renewable Energies Burst power to adjust wind turbine blades (Pitch control) Reduce sharp demand peaks and adjust panels in solar arrays Back-Up Power Short term bridge power to ensure continuous operation of critical systems Emergency backup power in various critical applications Burst Power Peak power assist for high power functions in various industries Quick Charge and Release Enables efficient Start/Stop function in automotive Regenerative braking & energy recovery Cold Starting For starting small and large engines Improving fuel economy and emission performance for a variety of vehicles
