UCW1H221MNL1GS

The UCW1H221MNL1GS is a chip-type aluminum electrolytic capacitor in Nichicon's UCW series designed for surface-mount applications. It delivers 220 μF at 50 V with low impedance across a wide temperature range and a long rated load life for demanding systems.

Engineered for automated assembly, AEC-Q200 qualification and RoHS compliance, this part targets high-reliability markets such as automotive electronics and other embedded systems that require stable bulk capacitance, ripple handling, and extended operating life.

Key Features

• Capacitance and Voltage — 220 μF rated capacitance at 50 V, providing bulk energy storage for power rails and decoupling in compact SMD formats.
• Low Impedance Performance — Specified impedance of 350 mΩ and low-impedance characteristics up to +105°C to support stable ripple performance over temperature.
• High Temperature Endurance — Rated for 7,000 hours at +105°C; after endurance testing capacitance change remains within ±30%, tan δ stays within 300% of initial specification, and leakage current remains at or below the initial specified value.
• Ripple Current Ratings — 335 mA at 120 Hz and 670 mA at 10 kHz, enabling effective smoothing of low- and high-frequency ripple in power systems.
• Operating Temperature Range — −25°C to +105°C for reliable operation across typical automotive and industrial ambient conditions.
• Assembly-Friendly SMD Package — Chip-type radial can in a surface-mount configuration sized 1.0 × 1.0 cm with recommended land size of 1.03 × 1.03 cm and carrier-tape compatible packaging for automated placement.
• Electrical Characteristics — Polarized electrolytic construction with capacitance tolerance of −20% to +20% and leakage current specification of ≤0.01 CV or 3 μA (whichever is greater) after two minutes at 20°C.
• Quality and Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and reliability-focused designs.

Typical Applications

• Automotive Power Filtering — Bulk smoothing and ripple suppression on vehicle power rails, leveraging the part’s AEC-Q200 qualification and long life at elevated temperature.
• Embedded Power Supplies — Energy storage and decoupling for DC–DC converters and regulators where compact SMD mounting and high ripple capability are required.
• Industrial Electronics — Bulk capacitance in controllers and instrumentation operating across −25°C to +105°C with extended endurance.

Unique Advantages

• Extended high-temperature life: Rated 7,000 hours at +105°C, providing predictable end-of-life behavior for long-running systems.
• Low-impedance behavior: 350 mΩ impedance and specified low-impedance range up to +105°C help minimize voltage ripple and improve transient performance.
• SMD compatibility for automated production: Carrier-tape compatible chip package and defined land pattern simplify pick-and-place and reflow assembly processes.
• Defined ripple handling: Separate ripple current specs at 120 Hz and 10 kHz support design decisions for both low- and high-frequency filtering requirements.
• Qualification and compliance: AEC-Q200 qualification and RoHS compliance help meet automotive and regulated market requirements.
