UCM1J621MNJ1MS

The UCM1J621MNJ1MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UCM chip-type, low-impedance family. It provides 620 µF capacitance at 63 V in a compact φ16 × 16.5 mm can-style SMD package designed for automated assembly.

Engineered for demanding environments, this part targets automotive and industrial power applications where high ripple handling, wide operating temperature range (−55 °C to 105 °C) and long-term endurance (5,000 hours at 105 °C) are required.

Key Features

• Capacitance & Voltage — 620 µF rated capacitance with a 63 V rating and ±20% tolerance, suitable for bulk energy storage and decoupling in high-voltage systems.
• Low-Impedance Chip Design — UCM series chip-type construction optimized for reduced ESR and improved performance across temperature, supporting stable filtering under load.
• High Ripple Current Capability — 870 mA low-frequency ripple current at 120 Hz and 1.74 A high-frequency ripple current at 10 kHz, enabling robust AC ripple handling in power stages.
• Leakage Current — Specified leakage current of 390.6 µA, consistent with electrolytic capacitor behavior for predictable standby and idle currents.
• Extended Endurance — Rated for 5,000 hours at 105 °C, supporting long-term operation in elevated-temperature environments.
• Automotive-Grade Reliability — AEC-Q200 qualification, demonstrating suitability for automotive electronic applications where component-level reliability is essential.
• Surface-Mount, Assembly-Ready Package — Radial can SMD package (φ16 × 16.5 mm) supplied in embossed carrier tape for automated pick-and-place and high-volume production.
• Wide Temperature Range & Compliance — Operates from −55 °C to 105 °C and is RoHS compliant.

Typical Applications

• Automotive Power Electronics — Bulk smoothing and decoupling in automotive power converters and control modules, leveraging AEC-Q200 qualification and 5,000 h endurance at 105 °C.
• DC–DC Converter Outputs — Output filtering in converters where high ripple currents (120 Hz and 10 kHz) must be managed reliably over temperature.
• Industrial Power Modules — Energy storage and ripple suppression in industrial drives and power distribution systems that require robust SMD packaging and long life at elevated temperature.

Unique Advantages

• High ripple-handling capacity: Specified ripple currents of 870 mA (120 Hz) and 1.74 A (10 kHz) reduce thermal stress and improve regulator stability under AC load.
• Long-term thermal endurance: 5,000 hours at 105 °C supports durability in hot operating environments and reduces maintenance or field-replacement frequency.
• Automotive-grade assurance: AEC-Q200 qualification provides a reliability baseline for automotive electronic designs.
• Assembly-optimized packaging: Embossed carrier taping enables high-throughput surface-mount assembly and consistent placement for mass production.
• Compact can-style SMD: φ16 × 16.5 mm radial can package offers high capacitance in a solderable surface-mount form factor for space-constrained boards.
• Regulatory compliance: RoHS compliant to support restricted-substances requirements.
