UWX1H220MCL1GB

The UWX1H220MCL1GB is a surface-mount aluminum electrolytic chip capacitor in Nichicon’s UWX series. It provides 22 µF capacitance at a 50 V rating in a compact radial can SMD package designed for automatic placement on high-density PC boards.

Key electrical and reliability attributes include a tanδ of 0.12 (measured at 20°C, 120 Hz), low leakage, AEC-Q200 rating, and a load life of 2000 hours at 85°C. Status: End Of Life (products in this series are scheduled for discontinuation and are not recommended for new designs).

Key Features

• Capacitance & Voltage — 22 µF capacitance with a 50 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Low Loss Characteristics — tanδ = 0.12 at 20°C, 120 Hz (rated voltage), supporting efficient filtering and decoupling in power stages.
• Leakage Performance — Specified leakage current of 11 µA for stable long-term operation in biased circuits.
• Ripple Handling — Low-frequency ripple current 52 mA (120 Hz) and high-frequency ripple current 78 mA (10 kHz) for smoothing and transient suppression.
• Reliability & Endurance — Load life of 2000 hours at 85°C with defined endurance limits for capacitance, tanδ and leakage.
• Automotive-Grade Rating — AEC-Q200 listed in specifications for applications requiring that qualification.
• Compact SMD Package — Chip-type radial can SMD with dimensions φ8 × 5.4 mm (D × L) and recommended land pattern 8.3 × 8.3 mm; supplied in embossed carrier tape for automatic assembly.
• Temperature Range & Compliance — Operating range −40°C to +85°C and RoHS compliant.

Typical Applications

• Automotive electronics — AEC-Q200-rated SMD capacitor for power filtering and decoupling in automotive control modules and subsystems within the specified temperature and life limits.
• Power supply filtering — Used for bulk smoothing and ripple suppression on 50 V rails in compact surface-mount layouts.
• High-density PCB assemblies — Chip-type radial can package and embossed carrier taping enable automated placement on space-constrained boards.

Unique Advantages

• Automotive-capable rating — AEC-Q200 listing supports use in designs requiring that qualification.
• Compact SMD form factor — φ8 × 5.4 mm chip-type can minimizes board area while remaining compatible with automated placement.
• Long load life at elevated temperature — 2000 hours at 85°C provides predictable endurance for applications operating near the upper temperature limit.
• Balanced electrical performance — Moderate tanδ, low leakage, and defined ripple currents make the part suitable for general-purpose filtering and decoupling tasks on 50 V rails.
• Production-ready packaging — Embossed carrier taping facilitates high-volume automated assembly.
• Regulatory compliance — RoHS compliant to meet environmental requirements.
