UWD1V680MCL1GS

The UWD1V680MCL1GS is a surface-mount aluminum electrolytic capacitor in Nichicon's UWD series, offered as a chip-type, low-impedance SMD can. It provides 68 µF nominal capacitance at a rated voltage of 35 V and is designed for use on high-density printed circuit boards that require compact, high-temperature-capable smoothing and decoupling components.

Key value propositions include a compact φ6.3×7.7 mm package with embossed carrier taping for automated placement, AEC‑Q200 qualification for automotive use, and rated performance to 105°C with defined ripple and endurance characteristics.

Key Features

• Electrical Performance  68 µF capacitance at 35 V with impedance of 340 mΩ and tanδ (DF) of 0.12 (measured at 20°C, 120 Hz), providing defined AC loss and impedance behavior.
• Ripple Handling  Specified ripple current ratings of 140 mA at 120 Hz and 280 mA at 100 kHz enable predictable performance across low and high frequency ripple conditions.
• Leakage & Tolerance  Leakage current specified at 23.8 µA and capacitance tolerance of ±20% support reliable bias behavior and component matching in designs.
• Thermal & Endurance  Operating temperature range −55°C to +105°C with a rated endurance of 2000 hours at 105°C for φ6.3 parts, supporting sustained elevated-temperature operation.
• Automotive-Grade Reliability  AEC‑Q200 qualification indicates suitability for automotive electronic applications requiring industry-recognized stress testing.
• Assembly & Package  Chip-type radial can SMD (φ6.3×7.7 mm) supplied in embossed carrier taping for automatic mounting; designed for surface mounting on high-density PCBs and compatible with high-temperature reflow processes documented in the UWD series.
• Environmental Compliance  RoHS-compliant construction.

Typical Applications

• Automotive electronics  AEC‑Q200-qualified capacitor for automotive electronic systems and modules requiring stable capacitance and endurance up to 105°C.
• Surface-mount, high-density PCBs  Chip-type SMD can and embossed carrier taping make the part well suited to automated placement on compact boards.
• 35 V rail smoothing and decoupling  68 µF capacitance with defined low/high frequency ripple current ratings and low impedance to support filtering on 35 V power rails.

Unique Advantages

• AEC‑Q200 qualification: Provides documented qualification for automotive-grade designs where recognized stress testing is required.
• High-temperature endurance: Rated to operate to +105°C with 2000 hours endurance, enabling use in elevated-temperature environments.
• Defined ripple and impedance specs: Low-frequency and high-frequency ripple current specifications (140 mA @120 Hz, 280 mA @100 kHz) and 340 mΩ impedance give predictable performance in power filtering roles.
• Reflow-compatible SMD package: Chip-type can in a compact φ6.3×7.7 mm footprint with embossed carrier taping supports automated pick-and-place and high-temperature reflow assembly processes.
• Controlled electrical characteristics: Tanδ = 0.12 at 20°C/120 Hz and leakage current defined at 23.8 µA enable engineers to design to specific loss and leakage budgets.
• RoHS compliance: Environmentally compliant construction for global deployment.
