UUJ2A221MNQ1MS

The UUJ2A221MNQ1MS is a surface-mount aluminum electrolytic capacitor from Nichicon’s UUJ series, offering 220 µF capacitance at a 100 V rating in a compact chip-type can (φ18 × 16.5 mm). It combines high-voltage capability with a form factor optimized for automated placement on high-density PCBs.

Engineered for demanding thermal environments, this device delivers extended endurance and controlled electrical characteristics—making it suitable for designs that require reliable bulk capacitance and stable performance across a wide operating temperature range.

Key Features

• Electrical Performance — 220 µF nominal capacitance, rated at 100 V with a tolerance of −20% to +20%; loss tangent (tanδ) specified at 0.08 (measured at 20°C, 120 Hz).
• Ripple and Leakage — Low-frequency ripple current 440 mA (120 Hz), high-frequency ripple current 660 mA (10 kHz), and leakage current specified at 660 µA.
• Reliability & Endurance — Lifetime of 5000 hours at 105°C with specified limits for capacitance change, tanδ, and leakage current after endurance testing.
• Temperature Range — Rated for operation from −55°C to +105°C.
• Package & Mounting — Chip-type radial can SMD (φ18 × 16.5 mm) designed for surface mounting; supplied in embossed carrier taping compatible with automatic mounting equipment. Recommended surface-mount land size: 1.83 × 1.83 cm.
• Polarization & Standards — Polarized aluminum electrolytic capacitor with AEC-Q200 rating and RoHS compliance.

Typical Applications

• Automotive power electronics — Provides high-voltage bulk capacitance in automotive modules where AEC-Q200 qualification and 100 V capability are required.
• High-density surface-mount PCBs — Chip-type can and embossed carrier taping enable automated placement on compact, densely populated boards.
• Elevated-temperature systems — Suited for circuits exposed to sustained high temperatures with a rated operating range to +105°C and 5000-hour endurance at 105°C.

Unique Advantages

• High-voltage capability: 100 V rating supports designs that require elevated DC voltage handling in an SMD format.
• Substantial bulk capacitance in a compact package: 220 µF in a φ18 × 16.5 mm chip-style can provides a balance of capacity and board space efficiency.
• Designed for automated assembly: Embossed carrier taping and standard surface-mount packaging accelerate production and reduce handling steps.
• Thermal endurance: 5000-hour life at 105°C gives predictable behavior for long-term thermal stress applications.
• Measured ripple handling and leakage specs: Specified low- and high-frequency ripple currents (440 mA / 660 mA) and leakage current (660 µA) allow engineers to size the capacitor with known electrical limits.
• Qualification and compliance: AEC-Q200 rating and RoHS compliance support use in regulated environments and industry-standard design flows.
