UCL1C821MNL1GS

The UCL1C821MNL1GS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UCL chip-type, low-impedance series. It provides 820 µF capacitance at a 16 V rating in a compact φ10 × 10 mm can-shaped SMD package with embossed carrier taping for automated assembly.

Designed for demanding environments, this capacitor combines high ripple-current capability, a wide operating temperature range, and AEC-Q200 qualification to address robust electronic power applications where long-term endurance and stable performance are required.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 16 V.
• Low Impedance Performance — Rated impedance of 80 mΩ and a tangent of loss angle (tan δ) of 0.16 measured at 20°C, 120 Hz for predictable AC behavior.
• Ripple Current Handling — Low-frequency ripple current of 425 mA at 120 Hz and high-frequency ripple current of 850 mA at 10 kHz to support power filtering and decoupling under dynamic loads.
• Leakage Current — Specified leakage current of 131.2 µA under standard measurement conditions.
• Thermal Range & Endurance — Rated for operation from −55°C to +105°C with an endurance life of 2000 hours at 105°C.
• Package & Mounting — Chip-type radial can designed for surface-mount placement; package footprint/land size: 10.3 mm × 10.3 mm (surface mount land size L:1.03 × W:1.03 cm). Supplied in embossed carrier taping for pick-and-place assembly.
• Reliability & Polarization — Polarized construction and AEC-Q200 rating for system-level reliability requirements.

Typical Applications

• Automotive electronics — AEC-Q200-rated capacitor suitable for power supply smoothing and decoupling in automotive modules that require stability across −55°C to +105°C and extended endurance.

Unique Advantages

• High ripple-current capability: 425 mA (120 Hz) and 850 mA (10 kHz) ratings reduce voltage ripple on power rails and improve regulator stability under variable loads.
• Low-impedance behavior: 80 mΩ impedance and specified tan δ deliver consistent AC performance for filtering and energy-storage needs.
• Wide operating temperature and endurance: −55°C to +105°C range with 2000 hours at 105°C supports long-term operation in thermally demanding environments.
• Automotive-grade reliability: AEC-Q200 rating aligns the part with qualification expectations for automotive system designs.
• Production-ready packaging: Embossed carrier taping simplifies high-volume pick-and-place assembly and inventory handling.
