Overview of UUN2A101MNQ1MS – 100 µF, 100 V Bi‑Polar Aluminum Electrolytic Chip Capacitor

The UUN2A101MNQ1MS from Nichicon is a chip‑type, bi‑polar aluminum electrolytic capacitor designed for surface mounting on high‑density PC boards. It delivers 100 µF capacitance at 100 V rated voltage with a bi‑polarized construction suited to circuits that may experience polarity reversals.

Targeted for general‑purpose electronic designs, this SMD can supports use in equipment that requires wide operating temperature range and long endurance, and it is applicable to automated assembly using carrier‑tape fed pick‑and‑place machines. The part is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

  • Capacitance & Voltage — 100 µF nominal capacitance with a 100 V rated voltage and tolerance of ±20% (‑20%~+20%).
  • Bi‑Polarized Construction — Bi‑polarized series design enables operation with polarity inversion and AC or bipolar signal conditions.
  • Surface‑Mount Chip Package — Chip type, radial can SMD package sized L: 2.15 cm × D: 1.8 cm with recommended land size L: 1.83 cm × W: 1.83 cm for high‑density PCBs.
  • Wide Temperature Range — Rated for operation from ‑55 °C to +105 °C.
  • Endurance — Demonstrated endurance of 2000 hours at 105 °C with polarity inversion testing; post‑test limits include capacitance change within ±20% and leakage at or below initial specified values.
  • Ripple Current Performance — Ripple current ratings include 310 mA at 120 Hz and 465 mA at 10 kHz; frequency coefficients for ripple current are provided in the series datasheet.
  • Electrical Loss & Leakage — Tangent of loss angle (tan δ) for the 100 V rating is specified at 0.09 (measured at 120 Hz, 20 °C). Leakage current specification (series) after 1 minute at 20 °C is not more than 0.03CV (µA).
  • Assembly Ready — Applicable to automatic mounting machines fed with carrier tape to support standard SMT production flows.

Typical Applications

  • General‑Purpose Power Filtering — Bulk decoupling and smoothing in power supply circuits on high‑density surface‑mount PCBs where 100 V rated capability is required.
  • Bipolar / AC‑Coupled Circuits — AC coupling, signal conditioning, or circuits that experience polarity reversal, leveraging the bi‑polarized construction.
  • Industrial and Consumer Electronics — Energy storage and ripple suppression in modules that require wide temperature operation (‑55 °C to +105 °C) and reliable endurance.

Unique Advantages

  • Bi‑polar capability: Allows use in applications with polarity inversion or AC conditions without requiring additional protection components.
  • High voltage rating: 100 V nominal rating addresses designs that need higher DC or peak voltage headroom.
  • Robust thermal endurance: 2000 hours at 105 °C demonstrates long‑term stability under elevated temperature stress.
  • SMD chip format for dense boards: Compact radial can SMD package and defined land pattern simplify placement on high‑density PCBs.
  • Measured electrical performance: Specified tan δ and leakage current limits provide verifiable loss and leakage behavior for engineering validation.
  • RoHS compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.
