UCM1J621MNS1MS

The UCM1J621MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly. It provides 620 µF capacitance at a 63 V rating in a compact φ16 × 16.5 mm can (SMD) package and is supplied on embossed carrier tape for automated placement.

Engineered for robust operation, this part supports an operating temperature range of −55°C to +105°C, a rated endurance of 5000 hours at 105°C, AEC‑Q200 qualification, and vibration-resistant construction—making it suited to demanding, high-reliability electronic assemblies.

Key Features

• Core Performance: 620 µF capacitance with ±20% tolerance at 120 Hz, 20°C, and a rated voltage of 63 V.
• Power Handling: Low-frequency ripple current 870 mA (120 Hz) and high-frequency ripple current 1.74 A (10 kHz), enabling effective smoothing and energy buffering on 63 V rails.
• Leakage and Loss: Specified leakage current of 390.6 µA and a low tangent of loss angle (tan δ) appropriate for the rated voltage class.
• Reliability & Endurance: 5000 hours endurance at 105°C with specified capacitance and tan δ limits after recovery to 20°C; designed to meet AEC‑Q200 requirements.
• Temperature Range: Wide operating range from −55°C to +105°C for elevated-temperature applications.
• Package & Mounting: Chip-type radial can (SMD) with dimensions φ16 × 16.5L mm, surface-mount land size L:1.63 × W:1.63 cm, and provided in embossed carrier tape for automatic mounting machines.
• Mechanical Robustness: Vibration-resistant construction suitable for assemblies exposed to mechanical stress.
• Compliance: RoHS compliant.

Typical Applications

• Automotive power electronics: Bulk smoothing and filtering on 63 V power rails in automotive control modules where AEC‑Q200 qualification and vibration resistance are required.
• Surface-mount power assemblies: Automated production lines benefit from embossed carrier taping and a chip-type SMD package for efficient placement and throughput.
• High-temperature environments: Energy storage and decoupling in systems operating up to +105°C with a 5000-hour rated endurance at that temperature.

Unique Advantages

• AEC‑Q200 Qualified: Meets the AEC‑Q200 rating for applications requiring automotive-level qualification and reliability.
• High Ripple Capability: Dual ripple specifications (870 mA @120 Hz and 1.74 A @10 kHz) support both low- and high-frequency smoothing needs on 63 V lines.
• Long Endurance at Elevated Temperature: Rated for 5000 hours at 105°C, helping extend maintenance intervals and system uptime.
• Surface-Mount Ready: Chip-type SMD can with embossed carrier tape simplifies integration into automated assembly processes and reduces BOM complexity.
• Vibration-Resistant Construction: Designed to withstand mechanical stress in mobile and industrial environments.
• Regulatory Compliance: RoHS compliance supports environmentally conscious designs.
