UUG1J331MNQ6MS

The UUG1J331MNQ6MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UUG series, offering 330 µF capacitance at a 63 V rating. Engineered for applications that require compact energy storage and effective ripple handling, it combines a chip-style radial can package with specifications tuned for demanding electronic systems.

Key use cases include power supply filtering, bulk capacitance and decoupling on higher-voltage rails in electronic systems. The part delivers verifiable electrical performance metrics—ripple current capability, low-frequency loss tangent, and defined endurance—that support reliable operation in temperature-stressed environments.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, suitable for bulk energy storage and smoothing applications.
• Voltage Rating & Polarization — Rated for 63 V and polarized, allowing use on higher-voltage DC rails where polarized electrolytic capacitance is required.
• Loss Tangent (tan δ) — tanδ = 0.10 measured at 20°C, 120 Hz, providing a defined measure of AC loss for design verification.
• Ripple Current Capability — Low-frequency ripple current 680 mA (120 Hz) and high-frequency ripple current 1.02 A (10 kHz), supporting applications with sustained or switching ripple load.
• Leakage Current — Specified leakage current of 623.7 µA (after 1 minute at 20°C), enabling predictable standby and bias behavior in DC circuits.
• Endurance & Temperature Range — Rated lifetime of 2000 hours at 85°C, with an operating temperature window of -40°C to +85°C for stable operation across a broad thermal range.
• Package & Assembly — Chip-type radial can SMD (φ12.5 × 21 mm) designed for surface-mount placement; packaging by embossed carrier taping for automated assembly.
• AEC‑Q200 Qualification — AEC‑Q200 rating for designs requiring recognized automotive-grade qualification.

Typical Applications

• Automotive electronics — Bulk filtering and decoupling on higher-voltage automotive subsystems where AEC‑Q200 qualification is required.
• Power supply filtering — Smoothing and ripple suppression for DC-DC converters and linear regulators on 63 V rails.
• Energy storage and hold-up — Local energy reservoir for transient loads and short-term hold-up in compact, board-mounted designs.

Unique Advantages

• High voltage capability: 63 V rating enables use on higher-voltage bus and intermediate-rail applications without series stacking.
• Measured ripple performance: Defined ripple current ratings at both low (120 Hz) and high (10 kHz) frequencies let designers select a capacitor matched to switching or mains-derived ripple profiles.
• Compact SMD can: φ12.5 × 21 mm package provides high capacitance in a board-mounted, chip-style form factor for space-constrained layouts.
• Automotive-grade reliability: AEC‑Q200 qualification and 2000-hour endurance at 85°C support use in temperature-challenged environments common to vehicle electronics.
• Predictable leakage and loss: Specified leakage current and tanδ allow more accurate power-loss and standby-current budgeting in system designs.
• Assembly-friendly packaging: Embossed carrier taping facilitates automated placement and throughput in production lines.
