UUG1J331MNJ6MS

The UUG1J331MNJ6MS from Nichicon is a chip-type aluminum electrolytic capacitor offering 330 µF capacitance at a 63 V rating in a surface-mount radial can package. It is designed for higher-capacitance SMD applications where compact bulk energy storage, smoothing and decoupling are required.

Targeted use cases include automotive and industrial power electronics where AEC-Q200 qualification, high ripple capability and extended endurance are important. The part combines a compact φ12.5×21 mm can with proven endurance and measurable ripple handling to support robust power designs.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance and a 63 V rated voltage for higher-voltage bulk and smoothing applications.
• Chip SMD Package — Chip-type, surface-mount radial can (φ12.5×21 mm; L: 2.1 × D: 1.25 cm) for PCB-mounted bulk capacitance in compact boards.
• Automotive-Grade Qualification — AEC-Q200 rating for use in automotive electronic systems and related applications.
• Endurance & Temperature — Rated operating temperature −40°C to +85°C with a lifetime/endurance of 2000 hours at 85°C.
• High Ripple Current Handling — 680 mA at 120 Hz (low frequency) and 1.02 A at 10 kHz (high frequency) to support switching converters and power stages.
• Leakage and Loss Characteristics — Specified leakage current of 623.7 µA; tan δ maximum of 0.10 at the 63 V rating (measured at 120 Hz, 20°C) per series datasheet limits.
• Production-Ready Packaging — Supplied in embossed carrier taping for automated surface-mount assembly and mass-production workflows.

Typical Applications

• Automotive Electronic Control Units (ECUs) — Bulk smoothing and decoupling in vehicle control modules where AEC-Q200 qualification is required.
• DC–DC Converter Output Filtering — Provides energy storage and ripple attenuation for intermediate and output stages of power converters.
• Power Supply Bulk Reservoirs — High-capacitance, board-mounted bulk capacitance for industrial and embedded power supplies.
• Motor Drive and Inverter Electronics — Supports power-stage filtering and transient energy needs with rated ripple current capability at low and high frequency.

Unique Advantages

• High capacitance in a compact SMD form: 330 µF in a φ12.5×21 mm chip package enables significant bulk energy storage without a large through-hole footprint.
• AEC-Q200 qualified: Meets automotive electronic component qualification requirements for designs that require automotive-grade components.
• Measured ripple capability: Specified ripple currents of 680 mA (120 Hz) and 1.02 A (10 kHz) help reduce heating and improve reliability in switching power applications.
• Proven endurance: 2000 hours at 85°C endurance rating supports long-term stability under elevated operating temperatures.
• Assembly-friendly packaging: Embossed carrier taping enables straightforward automated placement for high-volume manufacturing.
• Clear electrical loss limits: Specified tan δ (0.10 max at 63 V) and measured leakage current provide predictable performance for design validation.
