UUN1H221MNQ6MS

The UUN1H221MNQ6MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor optimized for surface mounting on high‑density printed circuit boards. Designed within Nichicon’s UUN series, it delivers 220 µF capacitance at a 50 V rating with bi‑polar operation across a wide temperature range.

This part targets general‑purpose electronics requiring higher capacitance in an SMD radial can package, offering RoHS compliance and compatibility with automated carrier‑tape mounting processes.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for predictable energy storage and decoupling performance.
• Bi‑Polar Construction: Bi‑polarized design suitable for AC or polarity‑reversing applications; endurance specified with polarity inversion during high‑temperature testing.
• Wide Temperature Range: Rated for operation from −55 °C to +105 °C, supporting designs that require broad thermal capability.
• Endurance & Reliability: 2000 hours at 105 °C endurance with defined limits for capacitance change, loss tangent, and leakage current after test (polarity inverted every 250 hours), supporting long‑term stability.
• Ripple Current Ratings: Specified ripple performance of 400 mA at 120 Hz and 600 mA at 10 kHz to support filtering and smoothing in power stages.
• Surface‑Mount Radial Can Package: Chip‑type radial, can‑style SMD package designed for high‑density PCBs and automatic mounting from carrier tape; recommended PCB land size L: 1.63 × W: 1.63 cm.
• RoHS Compliant: Meets RoHS directive requirements, enabling use in regulatory‑compliant product builds.

Typical Applications

• General Purpose Power Filtering: Used for bulk decoupling and smoothing in power supply sections where bipolar electrolytic capacitance is required.
• High‑Density PCB Assemblies: Suited to compact board layouts that require SMD radial can capacitors compatible with automated carrier‑tape mounting.
• AC‑Coupled or Bipolar Circuits: Applied where polarity may reverse or AC coupling is present, leveraging the bi‑polarized design and endurance test profile.

Unique Advantages

• Higher Capacitance in Chip‑Type Package: 220 µF capacity in a chip‑type radial can lets designers achieve larger capacitance without resorting to through‑hole parts.
• Wide Thermal Operating Window: −55 °C to +105 °C rating supports products exposed to demanding temperature ranges.
• Validated High‑Temperature Endurance: 2000‑hour endurance at 105 °C with polarity inversion and defined post‑test limits provides measurable reliability for thermal stress conditions.
• SMD Assembly Compatibility: Carrier‑tape and automatic mounting compatibility reduces manual handling and streamlines high‑volume assembly.
• Defined Ripple Handling: Specified ripple currents at 120 Hz and 10 kHz help designers size capacitors for expected AC stress in power and filtering applications.
• Regulatory Compliance: RoHS conformity enables deployment in regulated markets without additional material compliance concerns.
