UUN1H221MNJ6MS

The UUN1H221MNJ6MS is a chip‑type, bi‑polarized aluminum electrolytic capacitor from Nichicon’s UUN series, offering 220 µF capacitance at a 50 V rating in a surface‑mount radial can package. It is designed for surface mounting on high‑density PCBs and is compatible with automated placement via carrier tape.

Engineered for general‑purpose use, this capacitor supports broad operating temperatures (−55 °C to +105 °C) and includes endurance and ripple current characteristics suitable for designs that require higher capacitance in an SMD form factor.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 50 V, with a tolerance of ±20% (−20% to +20%).
• Bi‑Polarized Construction — Designed as a bi‑polarized series; endurance testing includes repeated polarity inversion to validate operation under polarity changes.
• Temperature Range — Rated for operation from −55 °C to +105 °C, supporting designs that require extended temperature capability.
• Endurance Specification — Specified lifetime of 2000 hours at 105 °C with rated voltage applied (polarity inverted every 250 hours); capacitance change remains within ±20% after the test.
• Ripple Current Performance — Rated ripple current listed as 400 mA at 120 Hz and 600 mA at 10 kHz; frequency coefficient data for 100–470 µF parts provides scaling across 50 Hz–10 kHz+.
• Leakage Current — Leakage current limit defined as 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: 2.15 × D: 1.6 cm with recommended land size L: 1.63 × W: 1.63 cm and black print marking on the case top.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑density PCBs — Surface‑mount chip type fits automated assembly and compact board layouts where higher capacitance is needed in limited space.
• Automated Production Lines — Carrier‑tape compatibility enables placement by automatic mounting machines for volume production.
• Wide‑temperature Electronics — Suitable for equipment that must operate across −55 °C to +105 °C while maintaining specified endurance.

Unique Advantages

• High Capacitance in SMD Form — 220 µF available in a chip‑type radial can package to deliver higher capacitance without requiring through‑hole components.
• Bi‑Polarized Robustness — Endurance validated with polarity inversion, providing tolerance to applications where polarity reversal may occur during operation or testing.
• Frequency‑aware Ripple Handling — Published ripple current values and frequency coefficients allow designers to size and predict ripple current capability from 50 Hz through 10 kHz and above.
• Wide Operating Temperature — −55 °C to +105 °C rating supports designs that demand thermal range and stability.
• Production‑friendly Packaging — Carrier‑tape feed compatibility and SMD form factor streamline automated assembly and reduce manual handling.
• Standards‑level Reliability Data — Endurance and shelf‑life conditions are specified (2000 h at 105 °C; 1000 h shelf‑life at 105 °C with post‑treatment), enabling reliability planning.
