UUN2A220MNJ1MS

The UUN2A220MNJ1MS is a Nichicon UUN series aluminum electrolytic, chip-type, bi-polarized capacitor designed for surface mounting on high-density PC boards. It delivers 22 µF at 100 V in a compact radial can SMD package suitable for automated assembly.

Targeted for general-purpose electronic equipment, this capacitor provides bi-polar construction for use in circuits where polarity may reverse, a wide operating temperature range from −55 °C to +105 °C, and a specified 2000-hour endurance at 105 °C for reliability in demanding environments.

Key Features

• Electrical Ratings — 22 µF capacitance at a rated voltage of 100 V with tolerance ±20% (measured at 120 Hz, 20 °C).
• Bi‑Polar Construction — Bi-polarized design enables operation where polarity may invert, as provided by the UUN series specification.
• Temperature & Endurance — Specified operating range −55 °C to +105 °C and endurance of 2000 hours at 105 °C (with polarity inversion every 250 hours during the endurance test).
• Leakage & Dissipation — Leakage current limit specified as not more than 0.03CV (µA) after one minute at 20 °C; tangent of loss angle (tan δ) at 100 V is specified as 0.09 max (120 Hz, 20 °C).
• Ripple Current & Frequency Response — Rated ripple current specified as 100 mA at 120 Hz and 200 mA at 10 kHz for this part; frequency coefficients provided by the series data.
• Package & Mounting — Chip-type radial can in SMD format designed for surface mounting on high-density PC boards and compatible with automatic mounting machines fed with carrier tape. Surface mount land size: 12.8 mm × 12.8 mm.
• Physical Dimensions — Body footprint L: 13.5 mm × D: 12.5 mm; maximum seated height 13.5 mm. Case top marking in black print.
• Environmental — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment — Suitable where standard electrolytic capacitor functions are required in compact surface-mount formats.
• High-density PCB assemblies — Chip-type radial can and carrier-tape compatibility make it suitable for automated placement on densely populated boards.
• Polarity-reversing or AC-coupled circuits — Bi-polarized construction supports applications where polarity may invert during operation.

Unique Advantages

• Wide temperature capability — Operation from −55 °C to +105 °C enables use across broad environmental conditions specified for the series.
• Qualified endurance — 2000 hours at 105 °C (with specified test conditions) provides a defined reliability metric for thermal stress.
• SMD-friendly package — Chip-type radial can designed for carrier-tape fed automated mounting, easing integration into high-volume production.
• Clear electrical limits — Specified leakage current, tan δ, and ripple current values allow designers to size and budget performance precisely.
• RoHS compliance — Meets applicable RoHS directives cited in the product specification.
