UCL1V221MNL1GS

The UCL1V221MNL1GS is a chip-type, low-impedance aluminum electrolytic capacitor from Nichicon designed for surface-mount assembly. It provides 220 µF capacitance at a 35 V rating with an operating temperature range from −55°C to +105°C, addressing demanding thermal and ripple-current environments.

Engineered for automotive and power-management use, this capacitor combines low impedance (80 mΩ), high ripple-current capability, and AEC-Q200 qualification to support robust power filtering and decoupling in electronic control and power systems.

Key Features

• Electrical Performance  220 µF nominal capacitance with ±20% tolerance and rated voltage of 35 V; impedance specified at 80 mΩ to minimize voltage ripple.
• Ripple Current Capability  Low-frequency ripple current of 425 mA at 120 Hz and high-frequency ripple current of 850 mA at 10 kHz for effective smoothing under dynamic loads.
• Leakage & Loss Characteristics  Specified leakage current of 77 µA and tanδ measured at 20°C, 120 Hz for predictable loss behavior in circuit designs.
• Thermal & Endurance  Wide operating temperature range from −55°C to +105°C and rated life of 2000 hours at 105°C for long-term high-temperature operation.
• Package & Mounting  Chip-type, radial can SMD package sized φ8×10L (L: 1 × D: 0.8 cm) designed for automated placement and provided in embossed carrier taping for surface-mount assembly.
• Qualification & Compliance  AEC-Q200 qualified and RoHS compliant, supporting use in regulated automotive and industrial environments.

Typical Applications

• Automotive Power Modules  Bulk smoothing and decoupling in engine control units, body control modules, and other in-vehicle power electronics where AEC-Q200 qualification and wide temperature range are required.
• DC‑DC Converters  Input/output filtering and energy storage in converter stages benefitting from 220 µF capacitance, low impedance (80 mΩ), and 850 mA high-frequency ripple capability.
• Infotainment & Instrumentation Power Rails  Stabilizing supply rails for displays, audio, and instrument clusters where consistent leakage, tanδ characteristics, and thermal endurance improve system reliability.

Unique Advantages

• Automotive-Grade Qualification: AEC-Q200 qualification enables deployment in vehicle electronics with defined stress performance.
• Low Impedance: 80 mΩ impedance reduces voltage ripple and supports tighter power-rail regulation.
• High Ripple Handling: 425 mA at 120 Hz and 850 mA at 10 kHz provide robust performance under both low- and high-frequency ripple conditions.
• High-Temperature Endurance: Rated for 2000 hours at 105°C, delivering predictable long-term behavior in elevated-temperature applications.
• Surface-Mount Ready: Chip-type radial can SMD in embossed carrier taping simplifies automated placement and assembly.
• Regulatory Compliance: RoHS-compliant construction for regulatory and environmental consistency.
