UUG1H221MNJ1MS

The UUG1H221MNJ1MS is a Nichicon UUG-series aluminum electrolytic chip capacitor offering 220 µF nominal capacitance at a 50 V rating in a compact surface-mount can. Designed for higher-capacitance SMD applications, it targets power filtering and energy-storage roles where board-level density, ripple-handling and endurance are important.

Its chip-type package (case size φ12.5 × 13.5 mm) with embossed carrier taping supports automated SMT assembly, while AEC-Q200 qualification and a rated lifetime of 2000 hours at 85°C address reliability requirements for demanding environments.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for 50 V rail smoothing and bulk energy storage.
• High ripple capability — Rated ripple currents of 450 mA at 120 Hz and 675 mA at 10 kHz support AC ripple absorption in power supplies and converters.
• Endurance and temperature range — Specified for 2000 hours at 85°C and an operating range of −40°C to +85°C, enabling stable performance across a wide ambient range.
• Leakage and loss characteristics — Leakage current specified at 0.03CV (≤ 330 µA for this part) and tan δ limits consistent with the UUG series, providing predictable DC leakage and dissipation behavior.
• Package and mounting — Chip-type radial can (SMD) in a φ12.5 × 13.5 mm package with surface-mount land size L: 1.28 × W: 1.28 cm and embossed carrier taping for pick-and-place processing.
• AEC-Q200 qualified — Built to the UUG series specification that includes AEC-Q200 rating for applications requiring recognized component-level automotive screening.

Typical Applications

• Automotive power modules — Bulk filtering and decoupling on 50 V rails in vehicle power electronics where AEC-Q200 qualification and 2000 h endurance at 85°C are required.
• DC–DC converters and power supplies — Output smoothing and ripple suppression on intermediate and high-voltage rails, taking advantage of the part’s rated ripple currents at both low and high frequencies.
• Industrial control — Energy storage and filtering in compact surface-mount assemblies operating across −40°C to +85°C.

Unique Advantages

• High capacitance in an SMD can: 220 µF in a φ12.5 × 13.5 mm chip package delivers substantial bulk capacitance while preserving board space.
• Designed for ripple duty: Specified ripple currents of 450 mA (120 Hz) and 675 mA (10 kHz) help manage both low‑ and high‑frequency ripple without overspecifying the design.
• Automotive-grade reliability: AEC-Q200 rating and a 2000-hour endurance at 85°C provide traceable qualification for demanding applications.
• Process-ready packaging: Embossed carrier taping supports automated placement and high-volume manufacturing workflows.
• Wide operating range: −40°C to +85°C operation enables use across varied environmental conditions.
