UUA0J221MCL1GS

The UUA0J221MCL1GS is a surface‑mount aluminum electrolytic capacitor in Nichicon’s UUA series designed for compact, high‑density PCB assembly. It delivers 220 µF capacitance at a 6.3 V rating in a φ6.3 × 7.7 mm SMD can package with embossed carrier taping for automated placement.

Engineered for long life and robust operation, this part supports an operating temperature range of −55 °C to +105 °C, AEC‑Q200 qualification, and a rated life of 3000 hours at 105 °C—making it suitable for demanding automotive and high‑reliability power filtering applications.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20% for predictable low‑voltage energy storage and decoupling.
• Long Life Endurance — Rated life of 3000 hours at 105 °C (chip size D ≤ 6.3), providing proven longevity under elevated temperature stress.
• Automotive‑grade Reliability — AEC‑Q200 qualification and RoHS compliance to meet demanding quality and environmental requirements.
• Low‑loss Performance — Tangent of loss angle (tan δ) of 0.28 measured at 20 °C, 120 Hz, supporting efficient filtering at low frequencies.
• Ripple Current Capability — Low‑frequency ripple current 120 mA (120 Hz) and high‑frequency ripple current 180 mA (10 kHz) for effective smoothing of power rails across a range of operating frequencies.
• Low Leakage — Measured leakage current of 13.86 µA, aiding in low‑power applications where minimized standby current is important.
• Compact SMD Can Package — φ6.3 × 7.7 mm radial can (SMD) with recommended land size L: 6.6 × W: 6.6 mm, optimized for space‑constrained board layouts and automated assembly.
• Production Ready — Available in embossed carrier taping and in mass production status for supply continuity and assembly flow.

Typical Applications

• Automotive electronic modules — Power‑rail smoothing and decoupling in control units where AEC‑Q200 qualification and high operating temperature are required.
• High‑density surface‑mount PCBs — Local energy storage and filtering in compact board layouts using the φ6.3 × 7.7 mm SMD can.
• Low‑voltage power supplies — Bulk and decoupling capacitor for 6.3 V rail designs that require moderate ripple handling and low leakage.

Unique Advantages

• Automotive‑grade confidence: AEC‑Q200 qualification and a 3000‑hour life at 105 °C support use in automotive and similarly demanding environments.
• Space‑efficient SMD form factor: Small φ6.3 × 7.7 mm footprint with embossed carrier taping simplifies placement on high‑density boards while keeping PCB area minimized.
• Balanced ripple handling: Defined ripple current ratings at both low (120 Hz) and high (10 kHz) frequencies give predictable thermal and filtering performance across typical operating spectra.
• Controlled electrical loss: Specified tan δ at 120 Hz helps engineers evaluate ESR‑related behavior and select the capacitor for stable filtering performance.
• Low standby draw: Measured leakage current of 13.86 µA supports designs where minimizing quiescent current matters.
