The UUX2D3R9MNL1GS is a Nichicon UUX series aluminum electrolytic capacitor in a compact surface‑mount radial can package. It delivers 3.9 µF capacitance at a 200 V rating with a wide operating temperature range and AEC‑Q200 qualification for automotive use.

Designed for space‑constrained, high‑voltage applications, this chip‑type part combines a small φ8 × 10 mm profile with endurance for extended operation at elevated temperatures, making it suitable for demanding power and automotive electronics environments.

Key Features

• Capacitance & Voltage — 3.9 µF nominal capacitance with a 200 V rated voltage and a tolerance of −20% to +20%.
• Dielectric Loss (tan δ) — tanδ of 0.20 measured at 20°C, 120 Hz, providing the specified dissipation characteristic for 200 V parts.
• Ripple Current Capability — Low‑frequency ripple current 34 mA (120 Hz) and high‑frequency ripple current 56.78 mA (10 kHz), enabling filtering and smoothing in high‑voltage circuits.
• Leakage Current — Specified leakage current of 131.2 µA after 1 minute at rated voltage and 20°C.
• Endurance & Temperature Range — Rated for 3000 hours at 105°C with an operating range of −40°C to +105°C, supporting long‑life operation in hot environments.
• Package & Mounting — Chip/radial can SMD package (φ8 × 10 L) optimized for surface‑mount assembly; supplied in embossed carrier taping for automated placement.
• Automotive Qualification — AEC‑Q200 rated and explicitly listed for automotive applications in product specifications.
• Polarized — Polarized aluminum electrolytic construction for correct orientation in DC circuits.

Typical Applications

• Automotive power electronics — AEC‑Q200 rating, 200 V capability and −40°C to +105°C operation suit in‑vehicle high‑voltage circuits and power modules.
• Compact high‑voltage SMD designs — φ8 × 10 mm radial can SMD package and defined land pattern (8.3 × 8.3 mm) facilitate space‑efficient placement on PCBs.
• High‑temperature environments — 3000 hours endurance at 105°C supports long‑term operation in thermally demanding systems.

Unique Advantages

• High‑voltage capability: 200 V rating enables use in medium‑voltage DC circuits where higher voltage margins are required.
• Automotive readiness: AEC‑Q200 qualification and automotive listing in the product data provide specification alignment for vehicle electronics designs.
• Compact SMD form factor: φ8 × 10 mm radial can SMD package reduces board footprint while maintaining electrolytic capacitance at high voltage.
• Extended high‑temperature endurance: 3000‑hour life at 105°C supports reliability in elevated ambient temperature applications.
• Controlled dielectric loss: tanδ = 0.20 (20°C, 120 Hz) for the 200 V variant, aiding predictable AC performance in filtering and decoupling roles.
• Production readiness: Mass production status and embossed carrier taping packaging simplify procurement and automated assembly integration.
