Frequently Asked Questions
What capacitance and voltage rating does the EEU-FR1E222S offer for power supply filter designs?
The Panasonic EEU-FR1E222S provides 2200 µF capacitance at a 25V DC working voltage with 20% tolerance. This large capacitance value makes it highly effective for smoothing output ripple in switched-mode power supplies and bulk energy storage in motor drive circuits operating up to 25V.
How does the 105°C temperature rating of the EEU-FR1E222S extend service life in industrial applications?
A 105°C rated aluminum electrolytic capacitor typically has a rated lifetime of 2000 hours or more at full temperature, compared to 1000 hours for 85°C types. In industrial equipment where ambient temperatures may reach 70–85°C, the EEU-FR1E222S maintains stable 2200 µF capacitance over a significantly longer service period before electrolyte degradation occurs.
Which motor drive or audio power supply circuits benefit most from a 2200 µF 25V radial capacitor?
The EEU-FR1E222S is well-matched to 24V DC motor drive bus filtering, class-AB audio amplifier rail decoupling at up to 25V, and output bulk storage in 12V to 24V SMPS designs. The 2200 µF value provides sufficient energy reserve to sustain load transients up to several amperes without dropping the bus voltage by more than a few hundred millivolts.
