UPW1A681MPD

The UPW1A681MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series, engineered for low impedance and high reliability in power electronics. With 680 µF capacitance at 10 V and a compact φ10 × 12.5 mm can, it targets switching power supplies and power-management stages that require high capacitance in a small footprint.

Designed for demanding thermal environments, the part supports operation from −55 °C to +105 °C and an endurance rating of 5000 hours at 105 °C, delivering consistent capacitance and leakage performance over extended high-temperature use.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 10 V and a tolerance of −20% to +20%, suitable for bulk energy storage and decoupling at low voltage rails.
• Low Impedance — Specified impedance of 180 mΩ and a tangent of loss angle (tan δ) of 0.19 (measured at 20 °C, 120 Hz) for improved ripple rejection and transient response.
• High Ripple Capability — Low-frequency ripple current of 570 mA (120 Hz) and high-frequency ripple current of 760 mA (10 kHz), enabling effective smoothing in both low- and high-frequency switching environments.
• Thermal Endurance — Rated operating temperature range from −55 °C to +105 °C with a life/endurance specification of 5000 hours at 105 °C.
• Automotive-Grade Qualification — Rated AEC-Q200, suitable for automotive electronics and other applications requiring component-level stress testing.
• Compact Radial Package — φ10 × 12.5 mm aluminum can with 5.0 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Leakage Performance — Specified leakage current of 204 µA, supporting predictable bias behavior after voltage application.

Typical Applications

• Switching Power Supplies — Bulk smoothing and ripple filtering in DC–DC converters and switching regulators where low impedance and compact size are required.
• Automotive Electronics — Power supply decoupling and energy buffering in automotive systems, leveraging the part’s AEC-Q200 rating and high-temperature endurance.
• Point-of-Load Decoupling — Local energy storage for transient currents at low-voltage rails, benefiting from the capacitor’s high capacitance and ripple-handling capability.
• Embedded Power Modules — Compact power modules and control boards that need reliable capacitance in a small radial-lead package with predictable lifetime at elevated temperatures.

Unique Advantages

• High Capacitance in a Small Footprint — 680 µF in a φ10 × 12.5 mm can minimizes PCB area while providing substantial energy storage for low-voltage rails.
• Improved Power Filtering — Low impedance (180 mΩ) and controlled tan δ support lower ripple and better transient performance in switching applications.
• Frequency-Resilient Ripple Handling — Rated ripple currents specified at both 120 Hz and 10 kHz (570 mA and 760 mA respectively) cover a wide range of switching frequencies.
• Designed for Elevated Temperatures — 5000-hour endurance at 105 °C ensures long-term stability in thermal stress environments.
• Automotive-Ready Qualification — AEC-Q200 rating provides an assured level of component stress testing for use in automotive and similarly demanding applications.
• Flexible Packaging — Available in bulk (no terminal forming) or bag packing to match assembly and stocking preferences.
