MINIATURE ALUMINUM ELECTROLYTIC CAPACITORS YXG SERIES

Category: Capacitors, Electronics, Rubycon America Inc

Overview

The Rubycon YXG series datasheet provides information about miniature aluminum electrolytic capacitors designed for high ripple current and long life, specifically suited for applications requiring a wide temperature range and stable performance. They are also in compliance with RoHS standards, indicating they are free from certain hazardous substances.

Specifications

Operating Conditions

These capacitors can operate within a temperature range of -40°C to +105°C, and are designed for rated voltages ranging from 6.3Vdc to 100Vdc. The capacitance tolerance is specified at ±20% at 20°C with a frequency of 120Hz.

Performance

The leakage current is defined by the expression I=0.01CV or 3uA, whichever is greater after a duration of two minutes, where I stands for leakage current, C for capacitance in pF, and V for rated voltage in Vdc. Dissipation factors range depending on the voltage rating and increase with higher capacitances. Upon endurance testing at 105°C with rated voltage and ripple current, the change in capacitance should remain within ±20% of the initial value, while the dissipation factor should not exceed 200% of the specified value for case size #D=6.3, and should not be more than the specified value for #D above 6.3. The leakage current is restricted as per defined maximum values depending on the case size.

Lifetime and Endurance

Life expectancy varies from 3000 to 6000 hours at the upper limit of the operating temperature range based on the rated voltage. The impedance ratio over low temperatures, represented by varying Impedance Ratio (MAX), also fluctuates according to rated voltage and frequency, ensuring stability under low temperature conditions.

Ripple Current Multiplier

The datasheet details a ripple current multiplier against a range of frequencies for different capacitance ranges, which essentially guides the user on how to adjust the ripple current based on operational frequency.

Dimensions and Part Numbering

Physical dimensions are provided for the capacitor sleeve, including length, diameter, and minimum sleeve length. The part number structure is explained as well, which includes series designation, rated voltage, capacitance, case size, tolerance, and optional sleeve coding.
