Product Description

Product Overview

The UHW series aluminum electrolytic capacitors are miniature-sized, high ripple current, and high reliability components. They offer lower impedance at high-frequency ranges, smaller case sizes, and high ripple current capabilities. These capacitors are compliant with the RoHS directive (2011/65/EU). They are designed for applications requiring high performance and endurance under demanding conditions.
