UUG1J221MNJ1MS

The UUG1J221MNJ1MS is a Nichicon UUG series chip-type aluminum electrolytic capacitor in a surface-mount radial can package. It delivers 220 µF capacitance at a 63 V rating in a compact φ12.5 × 16 mm SMD case designed for high-capacitance SMD implementations.

Engineered for automotive electronics and other demanding power applications, this capacitor combines high ripple-current capability, AEC-Q200 qualification, and a broad operating range (−40 °C to +85 °C) with a 2000-hour endurance at 85 °C for reliable performance in harsh environments.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with ±20% tolerance and a rated voltage of 63 V, providing energy storage and decoupling for medium-voltage rails.
• Chip-Type SMD Package: Surface-mount radial can package (φ12.5 × 16 mm) with embossed carrier taping for pick-and-place compatibility and compact board-level integration.
• Ripple Current Handling: Supports 580 mA at 120 Hz (low frequency) and 870 mA at 10 kHz (high frequency), enabling effective smoothing for both low- and high-frequency ripple components.
• Loss & Leakage Characteristics: Specified tan δ of 0.10 (measured at 20 °C, 120 Hz) and leakage current of 415.8 µA, for predictable AC loss and DC leakage behavior.
• Operational Temperature & Endurance: Rated for −40 °C to +85 °C with an endurance specification of 2000 hours at 85 °C, supporting long-term operation under elevated temperature conditions.
• AEC-Q200 Qualified: AEC-Q200 rating provided in the product data to support use in automotive-grade designs.

Typical Applications

• Automotive power rails: Energy storage and smoothing on vehicle DC power rails where 63 V rating and high ripple capability are required.
• Electronic control units (ECUs): Bulk decoupling and transient suppression in control modules benefiting from compact, high-capacitance SMD packaging and AEC-Q200 qualification.
• Power modules and DC–DC converters: Input/output filtering and ripple attenuation using the capacitor's specified low- and high-frequency ripple current performance.

Unique Advantages

• High capacitance in a compact SMD can: 220 µF in a φ12.5 × 16 mm package reduces board area compared with larger through-hole parts while delivering substantial energy storage.
• Broad ripple-frequency support: Rated ripple currents at 120 Hz and 10 kHz (580 mA and 870 mA respectively) provide designers quantified performance for both LF and HF filtering requirements.
• Automotive-grade reliability: AEC-Q200 rating and 2000 hours endurance at 85 °C offer verification for use in automotive electronics and other high-reliability systems.
• Temperature resilience: Specified operation from −40 °C to +85 °C ensures functionality across common automotive and industrial temperature ranges.
• Surface-mount assembly ready: Embossed carrier taping and consistent case dimensions support automated PCB assembly and high-volume production workflows.
