UUG2A221MNJ1MS

The UUG2A221MNJ1MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UUG series, delivering 220 µF of capacitance at a 100 V rating in a compact radial can SMD package (φ18 × 16.5 mm). Engineered for demanding environments, it targets automotive and other high-reliability power applications that require high-capacitance, high-voltage smoothing in an SMD form factor.

Key value comes from its combination of high voltage capability (100 V), substantial capacitance (220 µF), AEC-Q200 qualification, defined ripple current performance across low and high frequencies, and a rated endurance of 2000 hours at 85°C.

Key Features

• Electrical Performance — 220 µF capacitance with ±20% tolerance at 120 Hz, 20°C, supporting applications requiring bulk energy storage and smoothing at up to 100 V.
• High-Voltage Rating — Rated for 100 V operation, enabling use in higher-voltage power rails.
• Loss Characteristics — tanδ (DF) of 0.08 measured at 20°C, 120 Hz and 100 V, helping quantify ESR-related losses for thermal and ripple budgeting.
• Ripple Current Capability — Specified ripple current of 665 mA at 120 Hz (low frequency) and 997.5 mA at 10 kHz (high frequency), supporting both low- and high-frequency filtering duties.
• Leakage and Endurance — Leakage current specified at 660 µA and endurance of 2000 hours at 85°C with rated voltage applied, providing predictable long-term behavior under rated conditions.
• Automotive-Grade Qualification — AEC-Q200 rated, suitable for automotive and other applications that require that qualification standard.
• Compact SMD Can Package — Radial can SMD package, size φ18 × 16.5 mm, surface-mount land size L: 1.83 × W: 1.83 cm, enabling board-level placement in dense power modules.
• Production-Ready Packaging — Supplied in embossed carrier taping for automated surface-mount assembly; product status: mass production.
• Temperature Range — Operating temperature range from −40°C to +85°C, supporting a wide range of environmental conditions.

Typical Applications

• Automotive power electronics — Bulk smoothing and decoupling on 100 V class rails in automotive control and power modules, leveraging AEC-Q200 qualification and the rated endurance at 85°C.
• Power supply filtering — Input/output smoothing and ripple suppression in power converters and regulators where 220 µF at 100 V is required.
• Energy storage and hold-up — Short-duration energy hold-up and transient suppression in systems that demand predictable leakage and endurance characteristics.

Unique Advantages

• High-voltage, high-capacitance combination — 220 µF at 100 V provides significant energy density for applications that require higher operating voltages without parallel capacitor arrays.
• Quantified ripple performance — Specified ripple currents at 120 Hz and 10 kHz allow designers to size thermal and cooling margins with measured values.
• Automotive-grade reliability — AEC-Q200 rating and 2000-hour endurance at 85°C help reduce qualification overhead for vehicle-level designs.
• Surface-mount radial can form factor — φ18 × 16.5 mm SMD package with embossed carrier taping supports automated PCB assembly and compact board layouts.
• Predictable loss and leakage — tanδ of 0.08 and specified leakage current enable accurate modelling of power dissipation and standby behavior.
• Wide operating temperature — −40°C to +85°C range supports deployment across varied environmental profiles common in industrial and automotive systems.
