UUN1V101MNJ1MS

The UUN1V101MNJ1MS is a chip-type, bi-polarized aluminum electrolytic capacitor from Nichicon’s UUN series, offering a higher capacitance option in an SMD-compatible can package. It is designed for surface mounting on high-density printed circuit boards and is suitable for general-purpose electronic applications.

The part is specified for operation across a wide temperature range (−55°C to +105°C), is compatible with automated carrier-tape mounting, and is RoHS compliant.

Key Features

• Electrical: 100 µF, 35 V — Rated capacitance of 100 µF with a rated voltage of 35 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• Bi-Polarized Construction — Bi-polarized series design; endurance testing includes polarity inversion to validate performance with polarity changes.
• Temperature and Endurance — Operating temperature range from −55°C to +105°C with a rated endurance of 2000 hours at 105°C (voltage applied, polarity inverted every 250 hours).
• Ripple Current Performance — Specified ripple current of 180 mA at 120 Hz and 270 mA at 10 kHz; frequency-dependent ripple characteristics are provided for design sizing.
• Low Leakage — Leakage current specified as not more than 0.03 C·V (µA) after one minute’s application of rated voltage at 20°C.
• Surface-Mount Package — Chip-type radial can SMD package sized L: 1.35 × D: 1.25 cm with a surface-mount land recommendation of 1.28 × 1.28 cm; compatible with automatic mounting via carrier tape.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification — Marked with black print on the case top for part identification.

Typical Applications

• General Purpose Electronics — Suitable for circuits requiring a bi-polarized electrolytic capacitor in a surface-mount format.
• High-Density PCB Assemblies — Designed for surface mounting on high-density printed circuit boards where compact SMD can capacitors are required.
• Automated Assembly Lines — Formatted for carrier-tape feed and automatic mounting machines to support high-volume production.

Unique Advantages

• Wide temperature operating window: −55°C to +105°C rating supports designs exposed to broad environmental extremes.
• Validated endurance under polarity inversion: Endurance specified at 2000 hours with polarity inversion every 250 hours demonstrates suitability for applications where polarity can change.
• Surface-mount, high-capacitance chip format: Provides higher capacitance in a chip-type radial can SMD package, enabling compact board layouts.
• Measured ripple current data: Specified ripple current values at 120 Hz and 10 kHz allow designers to size capacitors for expected AC stress and frequency-dependent heating.
• Low leakage characteristic: Leakage current limit of 0.03 C·V (µA) after one minute gives a defined baseline for low-current designs.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
