UCM1K221MNS1MS

The UCM1K221MNS1MS is a Nichicon UCM series chip-type aluminum electrolytic capacitor designed for surface-mount applications. It delivers 220 µF at 80 V in a compact φ12.5 × 13.5 mm can, optimized for low-impedance performance and automated assembly.

Engineered for demanding temperature and vibration conditions, this RoHS-compliant, AEC-Q200-rated part offers high ripple handling and long-term endurance (5000 hours at 105°C), making it suitable for automotive and other high-reliability electronic designs.

Key Features

• Core Type: Chip-type aluminum electrolytic capacitor in an SMD radial can package suited for surface-mount assembly.
• Capacitance & Voltage: 220 µF rated capacitance with an 80 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Impedance / Loss: tanδ = 0.08 (max.) measured at 120 Hz, 20°C for 80 V units, supporting lower AC loss in filtering and decoupling roles.
• Ripple Current Capability: 525 mA at 120 Hz (low frequency) and 1.05 A at 10 kHz (high frequency) for improved handling of AC stress.
• Leakage Current: Specified leakage current of 176 µA after rated voltage application at 20°C.
• Temperature & Endurance: Operating range −55°C to +105°C with endurance of 5000 hours at 105°C under rated voltage.
• Mechanical & Assembly: Vibration-resistant construction and supplied in embossed carrier taping compatible with automatic mounting machines.
• Package & Footprint: Physical size φ12.5 × 13.5 mm (L: 1.35 × D: 1.25 cm) with recommended land size L: 1.28 × W: 1.28 cm for SMD placement.
• Compliance & Qualification: RoHS-compliant and AEC-Q200 qualified for applications requiring automotive-grade components.

Typical Applications

• Automotive electronics — AEC-Q200 qualification, high ripple capability, and 5000-hour endurance at 105°C make this capacitor suitable for automotive electronic modules requiring long-term reliability.
• High-temperature SMD assemblies — Rated for −55°C to +105°C and supplied in embossed carrier tape for automated placement in high-temperature operating environments.
• Compact board-level energy storage — 220 µF at 80 V in a φ12.5 × 13.5 mm package provides substantial capacitance in a small SMD footprint for space-constrained designs.

Unique Advantages

• High-voltage capacitance in a compact can: 220 µF at 80 V delivered in a φ12.5 × 13.5 mm SMD package conserves board area while providing useful bulk capacitance.
• Low-loss operation: tanδ of 0.08 at 120 Hz (20°C) for 80 V helps minimize AC-related dissipation in filtering and decoupling applications.
• Robust ripple handling: Specified 525 mA (120 Hz) and 1.05 A (10 kHz) ripple currents reduce temperature rise under AC conditions.
• Long high-temperature life: 5000 hours at 105°C under rated voltage supports applications with sustained elevated-temperature exposure.
• Automotive-grade qualification: AEC-Q200 rating and RoHS compliance provide traceable standards for regulated and automotive programs.
• Assembly-ready and vibration resistant: Embossed carrier taping for automatic mounting plus vibration-resistant construction improve manufacturing throughput and in-field durability.
