UWD1V221MCL1GS

The UWD1V221MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UWD series designed for surface-mount installation on high-density PCBs. It delivers 220 µF at 35 V with low impedance and defined ripple handling for power decoupling and smoothing in demanding environments.

Built for assembly processes that require high-temperature reflow, the part is AEC-Q200 qualified and RoHS compliant, making it suitable for automotive and other applications that demand long-term stability up to +105°C.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 35 V, ±20% tolerance (120 Hz, 20°C).
• Low Impedance Performance — Specified impedance of 90 mΩ supports lower ripple and improved transient response in power circuits.
• Ripple Current Ratings — 335 mA at 120 Hz and 670 mA at 10 kHz provide defined AC handling for filtering and decoupling.
• High-Temperature Endurance — Rated operating temperature range −55°C to +105°C with endurance of 5000 hours at 105°C.
• High-Temperature Reflow Compatibility — Corresponds with 260°C peak reflow soldering (recommended: 260°C peak for 5 s; 230°C over 60 s ×2 in series conditions noted), enabling modern Pb-free assembly processes.
• Package & Mounting — Chip type (radial, can - SMD) designed for surface mounting on high-density PC boards and compatible with automatic mounting from carrier tape.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Compact footprint: approximately 1 cm × 1 cm with specified surface-mount land size L: 1.03 × W: 1.03 cm.

Typical Applications

• Automotive Power Modules — Bulk smoothing and decoupling on power rails for ECUs and control modules where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC Converters — Output filtering and energy buffering in compact SMD designs benefiting from low impedance and defined ripple current ratings.
• High-Density PCB Power Distribution — Local decoupling and stabilization on tightly packed boards thanks to chip-type form factor and compatibility with automated mounting.

Unique Advantages

• Designed for Pb-free reflow processes: Recommended reflow conditions including 260°C peak allow use in modern high-temperature assembly flows.
• Automotive-grade qualification: AEC-Q200 qualification supports use in applications requiring standardized reliability criteria.
• High-temperature longevity: 5000 hours endurance at 105°C provides predictable lifetime performance in hot environments.
• Low impedance and defined ripple handling: 90 mΩ nominal impedance with specified ripple currents at 120 Hz and 10 kHz improves power stability and transient response.
• SMD chip format for dense layouts: Compact 1 cm × 1 cm footprint and carrier-tape compatibility simplify automated assembly on high-density PCBs.
• Regulatory compliance: RoHS conformity ensures alignment with common environmental requirements.
