UUE1A331MNS1GS

The UUE1A331MNS1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UUE series engineered for demanding environments. It delivers 330 µF capacitance at a 10 V rating in a compact surface-mount radial can package.

Designed for heavy-duty automotive electronics and other high-temperature applications, the part combines AEC-Q200 qualification, wide operating temperature capability, and RoHS compliance for use where reliability under thermal stress is required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 10 V with a tolerance of ±20%.
• Temperature Range — Rated to operate from −40 °C to +125 °C according to product specifications.
• High-temperature endurance (series) — The UUE series is load-life tested at 125 °C (series datasheet references 5000 hours of endurance), supporting prolonged operation in elevated temperatures.
• AEC-Q200 Qualified — Qualification for automotive-grade reliability as stated in the product data, suitable for automotive electronics where heavy-duty service is required.
• Low leakage (series specification) — Series datasheet specifies leakage current not more than 0.03CV (µA) after 1 minute at 20 °C.
• Ripple current capability — Rated ripple current: 127.3 mA at 120 Hz and 190 mA at 10 kHz, enabling stable filtering under AC conditions within specified limits.
• Compact SMD package — Chip-type surface-mount radial can package with nominal dimensions L: 1 × D: 1 cm and a recommended land size of 1.03 × 1.03 cm for PCB layout.
• Regulatory compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — Suited for automobile electronics where heavy-duty service and temperature endurance are indispensable; AEC-Q200 qualification is indicated in the product data.
• High-temperature electronics — Applicable in board-level designs that require components rated to operate up to 125 °C per the product specification.
• Surface-mount power modules — Chip-type SMD radial can package and defined land pattern make it suitable for compact PCB power and decoupling implementations.

Unique Advantages

• Automotive-grade reliability — AEC-Q200 qualification supports use in automotive electronics where enhanced reliability is required.
• High-temperature capacity — Specification to −40 °C to +125 °C plus series-level load-life testing at 125 °C provides confidence in thermal endurance.
• Compact footprint — 1 × 1 cm nominal package size and defined land dimensions enable space-efficient PCB layouts.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
• Measurable ripple handling — Published ripple current ratings at both low and high frequencies allow engineers to assess suitability for AC ripple and switching applications.
