UUG1H221MNQ1MS

The UUG1H221MNQ1MS is a surface-mount aluminum electrolytic capacitor from Nichicon's UUG series, offering 220 µF capacitance at a 50 V rating. Engineered for environments requiring AEC‑Q200 qualification and wide operating temperature capability, it delivers a balance of capacitance, ripple handling and endurance in a compact SMD can package.

Targeted at automotive and industrial electronic modules, this part combines a higher-capacitance chip-type form factor with rated performance data suitable for applications operating between −40°C and 85°C.

Key Features

• Capacitance & Tolerance: 220 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable bulk energy storage in compact footprints.
• Voltage Rating: 50 V rated voltage for mid-voltage power applications.
• Loss Angle (tan δ): Specified tan δ of 0.12 at 20°C and 120 Hz, enabling characterization of dissipation under rated conditions.
• Ripple Current Performance: Low-frequency ripple current 450 mA (at 120 Hz) and high-frequency ripple current 675 mA (at 10 kHz), supporting AC ripple in power circuits.
• Leakage Current: Specified leakage current of 330 µA (after 1 minute at 20°C), aiding in predictable bias behavior.
• Endurance: Rated for 2000 hours at 85°C with defined capacitance and tan δ limits after recovery to 20°C.
• Temperature Range: Operates from −40°C to 85°C, supporting a broad range of environmental conditions.
• Package & Mounting: Chip-type radial can in an SMD package (φ12.5 × 13.5 mm), surface-mountable with embossed carrier taping for automated placement; recommended land size L: 1.28 cm × W: 1.28 cm.
• AEC‑Q200 Rated: Conforms to AEC‑Q200 requirements, aligning the component with automotive-grade reliability expectations.

Typical Applications

• Automotive Electronics: Suited to automotive electronic modules that require AEC‑Q200-rated electrolytic capacitance within −40°C to 85°C.
• SMD Power Modules: Compact chip-type SMD package for modules needing 220 µF at 50 V in space-constrained designs.
• Industrial Control Electronics: Applicable in industrial systems that demand 2000-hour endurance at elevated temperatures and defined ripple performance.

Unique Advantages

• AEC‑Q200 Qualification: Provides a recognized automotive-grade reliability standard for use in demanding electronic environments.
• High Capacitance in a Small SMD Can: 220 µF capacitance in a φ12.5 × 13.5 mm footprint reduces board area compared with larger through-hole alternatives.
• Defined Ripple Capability: Separate low- and high-frequency ripple current specifications (450 mA at 120 Hz, 675 mA at 10 kHz) enable designers to size parts according to AC conditions.
• Long Endurance at Elevated Temperature: 2000 hours at 85°C with post-test limits for capacitance and dissipation ensures predictable life performance.
• Pick-and-Place Friendly Packaging: Embossed carrier taping supports automated assembly for higher-volume board production.
