UWD0J681MCL1GS

The UWD0J681MCL1GS is a surface-mount, chip-type aluminum electrolytic capacitor from Nichicon’s UWD series. It provides 680 µF capacitance at a 6.3 V rating in a compact φ8 × 10 mm can optimized for low impedance and high-temperature reflow processes.

This part targets high-density surface-mount assemblies and applications that require robust ripple handling, long endurance at elevated temperature, and compatibility with automated placement and carrier-tape mounting. It is RoHS compliant and AEC‑Q200 qualified.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with ±20% tolerance at 6.3 V rated voltage, specified at 20 °C, 120 Hz.
• Low Impedance Performance — Specified impedance of 170 mΩ and a tangent of loss angle (tan δ) of 0.28 (measured at 20 °C, 120 Hz), supporting effective decoupling and transient response in compact designs.
• Ripple Current Capability — Low-frequency ripple current 225 mA (120 Hz) and high-frequency ripple current 450 mA (10 kHz) for handling both line-frequency and switching noise.
• High-Temperature Endurance — Rated for operation from −55 °C to +105 °C with a 5000 hour endurance at 105 °C, ensuring long-term stability under elevated ambient conditions.
• Leakage & Reliability — Specified leakage current of 42.84 µA and endurance criteria that limit capacitance change and tan δ increase after life testing, consistent with robust operational behavior.
• Reflow & Assembly Ready — Chip-type design compatible with 260 °C peak reflow (recommended reflow condition provided), and supplied in embossed carrier tape for automatic mounting machines.
• Compact Surface-Mount Package — φ8 × 10 mm can (L: 1.0 × D: 0.8 cm) with recommended land pattern 8.3 × 8.3 mm to support high-density PCB layouts.
• Standards & Compliance — RoHS compliant and AEC‑Q200 qualified, addressing regulatory and automotive-grade qualification requirements.

Typical Applications

• Automotive electronic modules — AEC‑Q200 qualification and high-temperature endurance make this capacitor suitable for automotive electronics that require long-term stability at elevated temperatures.
• High-density surface-mount PCBs — Chip-type can and compact φ8 × 10 mm package are designed for use on tightly packed boards where space and placement reliability matter.
• Automated assembly environments — Supplied in embossed carrier taping and compatible with automatic mounting machines for streamlined production and consistent placement.

Unique Advantages

• High ripple tolerance: Specified low‑ and high‑frequency ripple ratings (225 mA at 120 Hz, 450 mA at 10 kHz) enable reliable smoothing and decoupling in mixed-frequency power systems.
• Long-term thermal reliability: 5000‑hour endurance at 105 °C provides predictable electrical performance over extended service life in hot environments.
• Low-loss construction: Low impedance (170 mΩ) and defined tan δ support efficient energy filtering and improved transient response in compact layouts.
• Assembly-ready format: Embossed carrier taping and reflow compatibility simplify automated production flow and reduce manual handling.
• Automotive-capable grading: AEC‑Q200 qualification addresses the needs of applications that require automotive-level component qualification.
• Regulatory compliance: RoHS compliance supports deployment in regulated manufacturing environments.
