UUX1A331MNL1GS

The UUX1A331MNL1GS is a surface-mount aluminum electrolytic capacitor from Nichicon’s UUX series, designed as a chip-type component with a wide temperature range. It delivers 330 µF of capacitance at a 10 V rating in a compact φ10 × 10L can SMD package and is intended for applications that require robust electrical performance across a broad operating temperature span.

Key attributes include AEC‑Q200 qualification, a wide operating temperature range from −55 °C to +105 °C, low leakage behavior, and defined ripple current capability, making it suitable for demanding electronics environments where long-term stability and reliability are required.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance with a rated voltage of 10 V and a capacitance tolerance of −20% to +20% at 120 Hz, 20 °C.
• Loss and Dissipation — Tangent of loss angle (tan δ) of 0.19 measured at 20 °C, 120 Hz for the 10 V rating, providing a defined dissipation characteristic for design verification.
• Leakage Current — Leakage current specified at 99 µA (per I = 0.03CV) after 1 minute’s application of rated voltage at 20 °C.
• Ripple Current Performance — Low-frequency ripple current of 318 mA at 120 Hz and high-frequency ripple current of 413.4 mA at 10 kHz, documented for filtering and decoupling assessments.
• Temperature and Endurance — Operating range from −55 °C to +105 °C with an endurance rating of 2000 hours at 105 °C under rated voltage conditions (capacitance change and tan δ limits apply per series specifications).
• Automotive-Grade Qualification — AEC‑Q200 rating, identifying the part for automotive electronics applications where this qualification is required.
• Package and Mounting — Compact radial can SMD (chip-type) with size φ10 × 10L and surface-mount land recommendation of 10.3 mm × 10.3 mm (1.03 × 1.03 cm); supplied in embossed carrier taping for automated placement.

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and wide temperature range make this capacitor suitable for electronic control units and other in-vehicle modules requiring stable capacitance under thermal stress.
• Power Filtering and Decoupling — Documented ripple current ratings at both low and high frequencies support use in power supply smoothing and decoupling tasks in compact surface-mount designs.
• Compact SMD Designs — The φ10 × 10L chip-type package and embossed carrier taping enable integration into space-constrained assemblies and automated manufacturing flows.

Unique Advantages

• AEC‑Q200 Qualified: Provides a known automotive qualification path for designers targeting vehicle electronics.
• Wide Operating Temperature: −55 °C to +105 °C range supports deployment across harsh thermal environments without sacrificing specified performance.
• Defined Endurance: 2000 hours at 105 °C under rated voltage gives a clear baseline for lifetime planning and reliability assessments.
• Measured Dissipation and Leakage Values: Specified tan δ (0.19 at 120 Hz, 20 °C) and leakage current (99 µA) allow engineers to model losses and standby behavior precisely.
• Dual-Frequency Ripple Data: Published ripple current figures at 120 Hz and 10 kHz support design decisions across both power-line and switching-frequency domains.
• SMT-Ready Packaging: Embossed carrier taping streamlines placement and handling in automated assembly processes.
