ECEV1VA4R7SR – PANASONIC

Overview

The Panasonic ECEV1VA4R7SR (EEE-1VA4R7SR) is a 4.7 µF, 35V radial aluminum electrolytic capacitor designed for surface-mount applications. Its primary function is energy storage and filtering, critical for stable DC voltage rails. A key design consideration for this component is managing ripple current; while rated for 2000 hours at 85°C, exceeding its specified ripple current limits will significantly degrade its lifespan and increase Equivalent Series Resistance (ESR), impacting circuit performance and potentially leading to premature failure. This AEC-Q200 qualified part offers a balance between capacitance, voltage rating, and operational stability for demanding environments.
