Product Overview
The UPW series of miniature-sized, low impedance, high reliability aluminum electrolytic capacitors are designed for switching power supplies. Offering smaller case sizes and lower impedance compared to the UPM series, these capacitors provide high reliability withstanding 2000 to 8000 hours of operation. They are compliant with the RoHS directive (2011/65/EU) and AEC-Q200 standards.
