UUG1H331MNJ1MS

The UUG1H331MNJ1MS is a chip-type aluminum electrolytic capacitor in a surface-mount radial can package, offering 330 µF capacitance at a 50 V rating. It is built for applications that require higher capacitance in a compact SMD form factor and includes performance attributes important for demanding electronic environments.

With AEC-Q200 qualification and an operating temperature range of -40°C to 85°C, this part targets automotive and other industrial applications that demand reliable bulk capacitance, defined ripple handling and a 2000-hour endurance at 85°C.

Key Features

• Capacitance & tolerance — 330 µF with ±20% tolerance (120 Hz, 20°C), delivering reliable bulk storage in a compact SMD component.
• Voltage rating — Rated for 50 V operation, suitable for mid-voltage power stages requiring stable capacitance at elevated voltages.
• Ripple current capability — Low-frequency ripple current 520 mA (120 Hz) and high-frequency ripple current 780 mA (10 kHz), supporting applications with AC ripple across a broad frequency range.
• Leakage current — Specified leakage current of 495 µA (measured after application of rated voltage at 20°C), allowing predictable power-loss budgeting.
• Endurance and temperature — Rated lifetime of 2000 hours at 85°C and an operating range from -40°C to 85°C, providing verified endurance under elevated-temperature stress.
• Package and mounting — φ12.5 × 13.5 mm can (L: 13.5 mm × D: 12.5 mm) in a surface-mount radial can configuration with recommended SMD land size of 12.8 × 12.8 mm; supplied in embossed carrier taping for automated placement.
• Qualification — AEC-Q200 rated, meeting the specified automotive component-level requirement listed for this part.
• Polarized design — Polar capacitor construction for correct-bias applications where polarity is controlled in the circuit.

Typical Applications

• Automotive electronics — For automotive modules that require AEC-Q200-qualified, high-capacitance SMD solutions with defined ripple-current performance and 2000-hour endurance at 85°C.
• Power management modules — Where 330 µF at 50 V and specified ripple current ratings are needed for bulk energy storage and smoothing in compact assemblies.
• Industrial control units — In circuits needing stable capacitance across -40°C to 85°C with predictable leakage and lifetime characteristics.

Unique Advantages

• High-capacitance chip form factor: 330 µF in a φ12.5 × 13.5 mm SMD can saves board space while delivering bulk storage capacity.
• Defined ripple handling across frequencies: Specified ripple current of 520 mA at 120 Hz and 780 mA at 10 kHz enables designers to match component selection to expected ripple spectra.
• Qualified for demanding use: AEC-Q200 rating provides documented component-level qualification for automotive and similar high-reliability environments.
• Long endurance at elevated temperature: 2000-hour rating at 85°C supports robust lifetime planning for products exposed to sustained thermal stress.
• Assembly-ready packaging: Supplied on embossed carrier tape for surface-mount placement, streamlining automated assembly and inventory handling.
• Predictable leakage behavior: Specified leakage current value (495 µA) simplifies power-loss and standby-current budgeting in system design.
