UUG2E470MNJ6MS

The UUG2E470MNJ6MS is a chip-type aluminum electrolytic capacitor from the Nichicon UUG series, designed for surface-mount installation and higher capacitance requirements. It provides 47 µF nominal capacitance at a 250 V rating with a ±20% tolerance (120 Hz, 20°C), and is targeted at automotive and industrial power applications that demand reliable bulk energy storage and ripple handling.

Key attributes include surface-mount packaging (φ16 × 21.5 mm), a wide operating temperature range of −40°C to +85°C, AEC-Q200 rating, and endurance specified for 2000 hours at 85°C—making it suitable where durability and consistent performance under temperature and vibration conditions are required.

Key Features

• Capacitance & Tolerance — 47 µF nominal capacitance with ±20% tolerance measured at 120 Hz, 20°C, suitable for bulk filtering and decoupling roles.
• High Voltage Rating — Rated for 250 V, supporting higher-voltage rails and DC-link applications.
• Ripple Current Handling — Designed with substantial ripple capacity: low-frequency ripple current 740 mA and high-frequency ripple current 1150 mA, enabling effective smoothing in power converters and switching circuits.
• Leakage Current — Specified leakage current of 705 µA, useful for estimating standby losses and bias drain in precision systems.
• Endurance & Temperature Range — Life rating of 2000 hours at 85°C and an operating range from −40°C to +85°C for sustained performance in harsh environments.
• Package & Mounting — Chip-type surface-mount “can” package, size φ16 × 21.5 mm with embossed carrier taping for automated placement.
• Automotive Qualification — AEC-Q200 rating, indicating suitability for automotive electronic assemblies and in-vehicle systems.

Typical Applications

• Automotive power electronics — Bulk energy storage and smoothing for DC-DC converters, power rails, and in-vehicle power systems.
• ECU and control modules — Decoupling and stabilization in engine control units, body controllers, and other electronic control modules.
• Power supply filtering — Input/output filtering and ripple attenuation in switching power supplies and converters.

Unique Advantages

• High-voltage capability: 250 V rating lets designers use a single-capacitor solution where higher DC voltage handling is required.
• Strong ripple performance: Elevated low- and high-frequency ripple current ratings reduce temperature rise and extend lifetime in switching applications.
• Automotive-ready: AEC-Q200 rating provides a clear qualifier for automotive design cycles and reliability requirements.
• Compact surface-mount form: Chip-type can in φ16 × 21.5 mm supports automated assembly and board-space-efficient power designs.
• Temperature and endurance specification: −40°C to +85°C operating range and 2000 h endurance at 85°C for predictable long-term behavior under thermal stress.
