UUG1J331MNQ1MS

The UUG1J331MNQ1MS is a surface-mount aluminum electrolytic chip capacitor in Nichicon's UUG series, designed for higher capacitance requirements in compact board-level applications. It offers 330 µF capacitance at a 63 V rating in a radial can SMD package (φ16 × 16.5 mm), providing a balance of energy storage and board footprint for demanding systems.

Targeted at automotive and industrial designs, this capacitor combines AEC-Q200 qualification, a wide operating temperature range (−40 °C to +85 °C), and endurance verified to 2000 hours at 85 °C for reliability under thermal stress.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 63 V rated voltage to support higher-voltage DC bus and energy-storage needs.
• Surface-Mount Chip Package — Chip-type aluminum electrolytic in a radial can SMD package (φ16 × 16.5 mm) for board-level mounting and compact integration.
• Automotive-Grade Reliability — AEC-Q200 rated series specification, aligning the part with automotive qualification expectations.
• Ripple Current Performance — Low-frequency ripple current of 680 mA (120 Hz) and high-frequency ripple current of 1.02 A (10 kHz), enabling effective AC ripple handling across frequencies.
• Leakage and Loss Characteristics — Specified leakage current of 623.7 µA and series tan δ characteristics for predictable loss and leakage behavior at 20 °C and rated voltage.
• Thermal Endurance — Endurance specified as 2000 hours at 85 °C with capacitance and dissipation limits defined, supporting long-term operation in elevated ambient temperatures.
• Packaging — Supplied in embossed carrier taping for automated placement and assembly.

Typical Applications

• Automotive power systems — Energy storage and bulk decoupling on 63 V-rated boards where AEC-Q200 qualification and elevated-temperature endurance are required.
• Power supply filtering — Smoothing and ripple reduction on higher-voltage DC rails using the capacitor’s 330 µF capacity and specified ripple current ratings.
• Board-level energy storage — Compact SMD implementation for designs that need higher capacitance without increasing board footprint.

Unique Advantages

• High capacitance in an SMD form factor: 330 µF provides substantial energy storage while the φ16 × 16.5 mm chip package keeps board area minimized.
• Higher-voltage capability: 63 V rating enables use on elevated DC rails where lower-voltage capacitors are unsuitable.
• Frequency-flexible ripple handling: Separate ripple current specifications at 120 Hz and 10 kHz (680 mA and 1.02 A) support both low- and high-frequency filtering needs.
• Automotive-grade qualification: AEC-Q200 rating supports deployment in automotive electronics requiring standardized reliability criteria.
• Defined thermal endurance: 2000 hours at 85 °C with specified post-test limits gives clear expectations for long-term performance under heat stress.
• Pick-and-place friendly packaging: Embossed carrier taping facilitates automated assembly for production volumes.
