UCM1J911MNJ1MS

The UCM1J911MNJ1MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UCM chip-type, low-impedance family. It delivers 910 µF of capacitance at a 63 V rating in a compact φ16 × 21.5 mm can suitable for automated placement (embossed carrier taping) and mass-production assembly.

Designed for demanding ambient conditions, this capacitor supports an operating temperature range from −55 °C to +105 °C and a rated endurance of 5000 hours at 105 °C, making it appropriate for automotive and other high-reliability power applications that require high capacitance, elevated ripple handling and long-term stability.

Key Features

• Electrical Performance 910 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 63 V for mid-voltage power systems.
• Low Loss / Loss Angle Low dissipation factor with tan δ = 0.08 measured at 20 °C, 120 Hz, helping minimize heating and power loss in filtering roles.
• High Ripple Capability Supports low-frequency ripple current of 1.165 A at 120 Hz and high-frequency ripple current of 2.33 A at 10 kHz for robust smoothing and decoupling.
• Leakage and Endurance Measured leakage current of 573.3 µA and long endurance: 5000 hours at 105 °C under rated voltage conditions.
• Temperature Range and Stability Operational from −55 °C to +105 °C with specified impedance stability across temperature for reliable performance in varied environments.
• Packaging and Mounting Chip-type SMD can (radial, can - SMD) in φ16 × 21.5 mm size, supplied in embossed carrier taping for automated pick-and-place mounting.
• Automotive Qualification and Compliance AEC-Q200 rated and RoHS-compliant, indicating suitability for automotive system designs and regulatory compliance.

Typical Applications

• Automotive power supply filtering — Bulk smoothing and decoupling on 63 V rails where AEC-Q200 qualification and 105 °C endurance are required.
• DC‑DC converter input/output filtering — High ripple current ratings (1.165 A at 120 Hz, 2.33 A at 10 kHz) support converter stability and transient handling.
• Power system hold‑up and smoothing — Large 910 µF capacity provides energy storage and voltage stabilization in compact SMD form.

Unique Advantages

• High capacitance in a compact SMD package: 910 µF in a φ16 × 21.5 mm chip-type can reduces board area while preserving bulk storage.
• Robust ripple handling: Combined low- and high-frequency ripple current ratings enable effective filtering across a broad spectrum of power-management tasks.
• Designed for elevated-temperature endurance: 5000 hours at 105 °C under rated voltage supports long-term reliability in hot operating environments.
• Automotive-capable: AEC-Q200 qualification supports use in automotive electronic subsystems that demand component-level qualification.
• Manufacturing-ready packaging: Embossed carrier taping is optimized for automated mounting, improving throughput for high-volume production.
• Regulatory compliance: RoHS compliance ensures alignment with common environmental requirements.
