Nichicon’s UBT Series Aluminum Electrolytic Capacitors are designed for high-temperature applications, specifically for use at temperatures up to +125°C. These capacitors exhibit exceptional reliability and durability with a lifespan that can range from 2000 to 10000 hours at the maximum rated temperature, making them well-suited for heavy-duty services in the automotive electronics industry.
Compliance and Environmental Considerations
The UBT Series is compliant with the RoHS directive (2011/65/EU), thereby meeting the required standards for restriction of hazardous substances in electrical and electronic equipment.
Features and Specifications
Category Temperature Range: These capacitors can operate in a broad temperature range from -40°C to +125°C for rated voltages between 10 to 250V, and from 25°C to +125°C for 350 to 450V.
Rated Voltage Range: The series offers capacitors with rated voltages spanning from 10 to 450V.
Capacitance Range: They are available in a range of capacitances from 4.7 to 4700µF.
Capacitance Tolerance: Capacitance tolerance is set at ±20% at 120Hz and 20°C.
Performance Characteristics
Leakage Current: The leakage current is controlled with different thresholds based on CV (capacitance x voltage) value, not exceeding 0.03CV or 4µA, which is the greater for CV ≤ 1000; and not exceeding 0.04CV+100µA for CV > 1000.
Stability at Low Temperature: Capacitance change remains within 30% or 20% of the initial value after 2000 to 10000 hours, depending on the rated voltage. Similarly, the dissipation factor stays within 200% or 300% of the initial specified value after 2000 to 5000 hours for 160 to 450V.
Endurance and Shelf Life
The capacitors, after 1000 hours of storage at 125°C without load and subsequent voltage treatment, maintain performance in line with the endurance characteristics detailed in the specification.
Physical Configuration
The capacitors are encased in a blue sleeve, marked with white lettering for easy identification. While the standard type possesses a Radial Lead Type configuration using a PET sleeve, an alternative polyolefin sleeve product can also be provided upon request. The datasheet outlines a type numbering system for identifying the voltage, capacitance, and series name, which includes features like capacitance tolerance, rated capacitance, and rated voltage denotations.
Additional Information
Details pertaining to the end seal configuration, formed or taped product specifications, minimum order quantities, and dimension tables can be found in subsequent pages of the datasheet, particularly referenced to pages 20, 21, 22, and beyond.
