UUN1V221MNQ1MS

The UUN1V221MNQ1MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor designed for surface mounting on high‑density PC boards. It delivers 220 µF at a rated voltage of 35 V in a compact SMD radial can package engineered for automated assembly.

Built for general‑purpose electronic equipment, the part provides wide temperature operation from −55°C to +105°C, long endurance (2000 hours at 105°C), and RoHS compliance for modern manufacturing requirements.

Key Features

• Electrical Characteristics – 220 µF / 35 V, ±20%
  Rated capacitance is 220 µF with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Bi‑Polarized Construction
  Designed as a bi‑polarized series for operation where polarity can invert; endurance testing includes polarity inversion every 250 hours.
• Wide Temperature & Endurance
  Operating temperature range is −55°C to +105°C; endurance rating is 2000 hours at 105°C with the rated voltage applied per the series specification.
• Ripple Current Capability
  Specified ripple current is 330 mA at 120 Hz and 495 mA at 10 kHz for this capacitance and package size.
• Package & Mounting
  Chip‑type radial can SMD package (size L: 1.65 × D: 1.6 cm) with recommended surface‑mount land dimensions of 1.63 × 1.63 cm; compatible with carrier‑tape feeding for automated placement.
• Loss & Leakage Characteristics
  Series-level specifications include a maximum tan δ of 0.14 at 35 V (measured at 120 Hz, 20°C) and a leakage current defined as not more than 0.03CV (µA) after one minute at 20°C.
• Environmental Compliance
  Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronic equipment
  Suitable where a bi‑polarized SMD electrolytic capacitor is required for compact assemblies and general power or signal conditioning roles.
• High‑density surface‑mount PCBs
  Chip‑type radial can SMD packaging fits tight board real estate and automated placement workflows.
• Automated assembly lines
  Designed for use with carrier‑tape feeding and automatic mounting machines to support high‑volume production.
• Wide‑temperature environments
  Useful in equipment exposed to broad ambient ranges up to +105°C where long endurance is required.

Unique Advantages

• Compact high capacitance: 220 µF in a chip‑type SMD radial can enables higher bulk capacitance in space‑constrained designs.
• Bi‑polarized flexibility: Construction and series test procedures accommodate polarity inversion scenarios without compromise to specified endurance.
• Engineered for automated assembly: Carrier‑tape compatibility and surface‑mount format streamline pick‑and‑place production.
• Specified ripple handling: Rated ripple currents (330 mA at 120 Hz, 495 mA at 10 kHz) help designers size capacitors for application frequency ranges.
• Long elevated‑temperature life: 2000 hours at 105°C endurance provides predictable performance in sustained high‑temperature operation.
• Regulatory compliance: RoHS conformity supports modern environmental and manufacturing requirements.
