UUX1A221MNL1GS

The UUX1A221MNL1GS is a surface‑mount aluminum electrolytic capacitor in Nichicon’s UUX series, offering 220 µF capacitance at a 10 V rating in a compact chip‑type can package. It is designed for applications that require robust capacitance, high ripple handling, and wide temperature operation in an SMD form factor.

Key differentiators include AEC‑Q200 qualification, a wide operating range from −55°C to 105°C, and a rated endurance of 2000 hours at 105°C, making this part suitable for demanding embedded and automotive electronic assemblies.

Key Features

• Capacitance & Voltage — 220 µF capacitance with a 10 V rated voltage and ±20% tolerance, suitable for bulk decoupling and energy storage in low‑voltage power rails.
• Compact SMD Can Package — φ8 × 10 mm can (L: 1.0 × D: 0.8 cm) in a chip‑type radial SMD package, enabling board space savings for compact assemblies.
• Temperature Range — Rated for −55°C to 105°C operation, supporting designs that encounter wide ambient temperature variations.
• Endurance — 2000 hours life at 105°C under rated voltage, providing predictable aging characteristics for long‑life applications.
• Ripple Current Performance — Low‑frequency ripple handling of 173 mA (120 Hz) and high‑frequency ripple handling of 224.9 mA (10 kHz) for effective smoothing in power converters and regulators.
• Loss and Leakage — Tangent of loss angle (tanδ) 0.19 measured at 20°C, 120 Hz, and a specified leakage current of 66 µA, supporting controlled dissipation and low standby current.
• Automotive Grade — AEC‑Q200 rating for passive components, suitable for use in automotive electronics where this qualification is required.
• Production and Packaging — Supplied in embossed carrier taping; product is in mass production for stable supply and automated assembly.

Typical Applications

• Automotive Electronics — Suitable for power supply filtering and decoupling in automotive control modules where AEC‑Q200 qualification and wide temperature range are required.
• Compact Power Modules — Ideal for DC‑DC converters and regulator output smoothing on space‑constrained SMD boards thanks to its chip‑type can footprint.
• Harsh‑Environment Embedded Systems — Used in embedded systems operating across −55°C to 105°C that need stable capacitance and endurance at elevated temperatures.

Unique Advantages

• Automotive‑grade reliability: AEC‑Q200 qualification aligns the part with automotive component requirements for passive devices.
• Wide operating temperature: −55°C to 105°C support lets designers use the same component across varied thermal environments.
• High ripple capability: Specified LF and HF ripple currents (173 mA @ 120 Hz, 224.9 mA @ 10 kHz) enable effective filtering in switching power applications.
• Predictable endurance: 2000 hours at 105°C with defined capacitance and tanδ stability provides clear lifecycle expectations for designs.
• Compact SMD form factor: φ8 × 10 mm chip‑type can and defined land pattern (8.3 × 8.3 mm) facilitate automated placement and compact PCB layouts.
• Production ready: Embossed carrier taping and mass production status support high‑volume assembly processes.
