UUG2W4R7MNJ1MS

The UUG2W4R7MNJ1MS is a surface-mount aluminum electrolytic capacitor from Nichicon’s UUG series, designed for high-voltage, compact power designs. It provides 4.7 µF capacitance at a 450 V rating in a chip-style radial can SMD package sized φ12.5 × 13.5 mm.

Engineered for reliability in demanding environments, this part carries an AEC-Q200 rating and delivers specified ripple, leakage and loss characteristics with an endurance rating of 2000 hours at 85°C—making it suitable for high-voltage filtering and decoupling tasks in constrained assemblies.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal capacitance with tolerance of -20% to +20% measured at 120 Hz, 20°C.
• High Voltage Rating — Rated for 450 V, enabling use in high-voltage DC circuits and power sections that require elevated voltage capability.
• Package & Mounting — Surface mount radial can (chip type) with case dimension φ12.5 × 13.5 mm and a surface-mount land size of 1.28 × 1.28 cm; supplied in embossed carrier taping for automated assembly.
• Thermal & Endurance — Operating temperature range -40°C to +85°C with a rated endurance of 2000 hours at 85°C.
• Ripple Current Performance — Low-frequency ripple current 115 mA (120 Hz) and high-frequency ripple current 184 mA (10 kHz), useful for both mains-frequency and higher-frequency ripple handling.
• Electrical Loss & Leakage — Loss tangent (tan δ) of 0.25 measured at 20°C, 120 Hz, and a measured leakage current of 184.6 µA.
• Reliability Qualification — AEC-Q200 rated, suitable for designs targeting automotive-grade component qualifications.
• Polarized Component — Polarized electrolytic construction; observe polarity in circuit placement.
• Product Status — End Of Life; check availability and lifecycle status before design-in.

Typical Applications

• Automotive power modules — AEC-Q200 rating and 450 V capability make it suitable for high-voltage automotive power electronics and auxiliary power sections requiring compact filtering components.
• High-voltage DC filtering — Use for DC link decoupling and smoothing in high-voltage power supplies and converters where a 450 V rating is required.
• Space-constrained power assemblies — Chip-type radial can SMD package supports compact board layouts with automated placement and embossed carrier taping for production assembly.

Unique Advantages

• High-voltage capability: 450 V rating enables deployment in higher-voltage DC circuits without stepping up to larger component families.
• Compact SMD chip form: φ12.5 × 13.5 mm can-style SMD packaging balances capacitance and board-space efficiency for tight layouts.
• Automotive-grade qualification: AEC-Q200 rating provides documented qualification for automotive applications and higher confidence in reliability under qualifying conditions.
• Specified ripple performance: Defined ripple current numbers at 120 Hz and 10 kHz allow designers to size components against actual ripple loading conditions.
• Long endurance at elevated temperature: 2000 hours at 85°C provides an indicator of expected life under sustained high-temperature operation.
• Production-ready packaging: Supplied on embossed carrier taping to support automated pick-and-place and reflow assembly workflows.
