Product Description

Product Overview

The UUD series aluminum electrolytic capacitors are designed for surface mounting on high-density PC boards, offering low impedance and suitability for automatic mounting machines fed with carrier tape. These capacitors are compliant with the RoHS directive (2011/65/EU, (EU)2015/863) and AEC-Q200 standards. They are engineered for applications requiring reliable performance up to +105C.

Technical Specifications

Item	Specification
Category Temperature Range	-55 to +105C
Rated Voltage Range	6.3 to 50V
Rated Capacitance Range	1 to 1500F
Capacitance Tolerance	20% at 120Hz, 20C
Leakage Current	After 2 minutes' application of rated voltage at 20C, leakage current is not more than 0.01 CV or 3 (A), whichever is greater.
Endurance	The specifications listed shall be met when the capacitors are restored to 20C after the rated voltage is applied for 5000 hours (2000 hours for D = 4, 5 and 6.3) at 105C.
Shelf Life	After storing the capacitors under no load at 105C for 1000 hours and then performing voltage treatment based on JIS C 5101-4 clause 4.1 at 20C, they shall meet the specified values for the endurance characteristics.
Resistance to soldering heat	The capacitors are kept on a hot plate for 30 seconds, which is maintained at 250C. They shall meet the characteristic requirements when removed and restored to 20C.
