UPW1A682MHD

The UPW1A682MHD is a miniature, low-impedance aluminum electrolytic capacitor in a radial-can package, designed for high-reliability power applications. With 6.8 mF capacitance at 10 V, an operating temperature range of -55°C to 105°C and AEC-Q200 rating, it targets demanding designs that require high bulk capacitance, robust ripple handling and long life.

Its combination of low ESR (36 mΩ), high ripple current capability and long endurance (8000 hours at 105°C) makes it well suited for switching power supplies, DC–DC converters and other power-rail stabilization roles in industrial and automotive-grade electronics.

Key Features

• High Capacitance, Low Voltage — 6800 µF at 10 V provides substantial bulk energy storage for power-rail smoothing and hold-up in low-voltage systems.
• Low Impedance — Rated impedance of 36 mΩ reduces voltage ripple under load and improves transient response in switching circuits.
• High Ripple Current Capability — Low-frequency ripple current 2.5585 A (120 Hz) and high-frequency ripple current 3.01 A (10 kHz) support heavy AC loading and switching environments.
• Long Endurance — 8000 hours life at 105°C under rated conditions, supporting sustained operation in elevated-temperature environments.
• Wide Temperature Range — Specified from -55°C to +105°C for use across a broad set of thermal conditions.
• Electrical Loss Characteristic — tanδ (dissipation factor) of 0.29 measured at 20°C, 120 Hz, providing a quantified loss metric for thermal and filtering design.
• Polarized Radial-Lead Package — φ16 × 30.5 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting; available in bulk (no terminal forming) or bag packing.
• Automotive-Grade Qualification — AEC-Q200 rating for use in automotive and other demanding applications where component-level reliability matters.
• Leakage Current — Specified leakage current of 2040 µA for voltage-hold and insulation planning in circuit designs.

Typical Applications

• Switching Power Supplies — Bulk capacitance and low ESR reduce output ripple and improve load-transient performance in SMPS designs.
• DC–DC Converters — Supports input/output filtering and energy buffering for converters operating near 10 V rails.
• Automotive Electronics — AEC-Q200 rating and wide temperature range make it suitable for power-stabilization tasks in in-vehicle systems.
• Power Rail Hold-Up — High capacitance and ripple capability provide short-term energy storage and sag protection on low-voltage rails.

Unique Advantages

• High Bulk Energy in a Small Can: 6800 µF in a φ16 × 30.5 mm package delivers large capacitance where board space is limited.
• Improved Power-Stage Performance: Low impedance (36 mΩ) and high ripple ratings reduce voltage ripple and heat build-up at switching frequencies.
• Designed for Harsh Environments: Rated from -55°C to 105°C with 8000 hours endurance at 105°C, enabling reliable operation in elevated-temperature applications.
• Automotive-Grade Reliability: AEC-Q200 qualification supports deployment in automotive and similarly demanding electronic systems.
• Clear Mechanical Footprint: Radial lead spacing of 7.5 mm (±0.5 mm) and through-hole can package simplify PCB layout and mechanical mounting.
• Production-Ready Packaging: Available in bulk or bag packing and listed as mass production for straightforward procurement and assembly.

Why Choose UPW1A682MHD?

UPW1A682MHD combines large capacitance, low impedance and long life in a compact radial-can package, making it a practical choice for engineers building power systems that demand stable rails and durable components. Its AEC-Q200 rating and extended temperature tolerance position it for use in both industrial and automotive-focused designs.
