UUG2G4R7MNQ1MS

The UUG2G4R7MNQ1MS is a chip-type aluminum electrolytic capacitor in Nichicon's UUG series, offering 4.7 µF capacitance at a 400 V rating. It is a polarized, surface-mount radial can (SMD) designed for applications that require high-voltage handling in a compact package.

With AEC‑Q200 qualification and a rated operating temperature range of −40°C to 85°C, this part targets automotive and other demanding environments that require reliable high-voltage bulk and decoupling capacitance in compact surface-mount form factors.

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 400 V operation, enabling use in high-voltage power rails and conversion stages.
• Packaging & Mounting — Chip-type radial can SMD package for surface-mount assembly; package footprint (land size) is L: 1.28 × W: 1.28 cm and physical size L: 1.35 × D: 1.25 cm.
• Reliability & Lifetime — Endurance characterized to 2000 hours at 85°C; designed to meet endurance requirements after recovery to 20°C.
• Temperature Range — Rated for operation from −40°C to 85°C, suitable for temperature-variable systems.
• Ripple Current Capability — Specified ripple current of 115 mA at 120 Hz and 184 mA at 10 kHz, with frequency coefficients available for different frequency bands.
• Leakage Current Specification — Leakage current limited by the series specification: after 1 minute at rated voltage and 20°C, leakage current is not more than 0.03 × C × V (µA).
• AEC‑Q200 Rated — Series-level AEC‑Q200 rating indicated in the product data for applications requiring automotive-grade qualification.

Typical Applications

• Automotive Power Electronics — Suitable for high-voltage bulk and decoupling in automotive power conversion and control modules that require AEC‑Q200‑level components.
• High-Voltage DC/DC Converters — Used on input or intermediate rails where 400 V rating and compact SMD mounting reduce board area while providing necessary capacitance.
• Industrial Power Supplies — Provides high-voltage energy buffering and ripple attenuation in compact power-supply designs.

Unique Advantages

• High-Voltage Capability: 400 V rating enables direct use on elevated DC buses and high-voltage conversion stages without additional series components.
• AEC‑Q200 Qualification: Series-level AEC‑Q200 rating supports integration into automotive designs that require supplier-level automotive qualification.
• Compact SMD Radial Can: Chip-type radial can package with a small land-size footprint enables higher component density on surface-mount assemblies.
• Temperature and Endurance Characterized: Rated for −40°C to 85°C with endurance specified at 2000 hours at 85°C, supporting designs with elevated temperature exposure.
• Defined Ripple Performance: Published ripple current values at multiple frequencies (115 mA at 120 Hz, 184 mA at 10 kHz) and frequency coefficients help predict in-circuit heating and lifetime.
• Controlled Leakage: Leakage current limit (0.03CV after 1 minute at 20°C) provides a predictable parameter for bias and standby calculations.
