UPW1V331MPD6

The UPW1V331MPD6 is a miniature, radial-leaded aluminum electrolytic capacitor in Nichicon's UPW series designed for low impedance and high reliability. It delivers 330 µF at 35 V in a compact φ8×20 mm can with 3.5 mm lead spacing, intended for power filtering and decoupling in compact electronic power systems.

Engineered for extended endurance, the part is specified for operation from -55°C to +105°C with a rated lifetime of 3000 hours at 105°C, and carries AEC-Q200 qualification for demanding applications.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a 35 V rated voltage with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Low impedance / loss — Specified impedance of 130 mΩ and tanδ = 0.12 (20°C, 120 Hz) for improved ripple performance.
• Ripple current capability — Low-frequency ripple current 646.8 mA at 120 Hz and high-frequency ripple current 995 mA at 10 kHz, supporting switching supply loads.
• Leakage current — Specified leakage current of 346.5 µA.
• High-temperature endurance — Rated lifetime of 3000 hours at 105°C under rated conditions.
• Wide operating range — Operating temperature from -55°C to +105°C for broad environmental suitability.
• Compact radial package — φ8×20 mm can with 3.5 mm lead spacing (lead spacing tolerance ±0.5 mm); radial lead mounting for through-hole assemblies.
• Reliability features — Miniature, low-impedance construction with a pressure relief vent for safe operation in radial lead form.
• Packaging — Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly workflows.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling where low impedance and high ripple handling improve regulator stability.
• Automotive Electronics — Use in automotive electronic modules and power systems that require AEC-Q200-qualified components and high-temperature endurance.
• Power Rail Filtering — Input/output filtering and decoupling on DC power rails in compact through-hole designs.

Unique Advantages

• Compact, high-capacitance package — 330 µF in a φ8×20 mm can conserves PCB area while delivering substantial bulk capacitance.
• Low-impedance performance — 130 mΩ impedance and a controlled tanδ improve ripple suppression and reduce voltage ripple on power rails.
• Designed for ripple-heavy environments — Specified ripple currents at both low and high frequencies support switching-regulator applications.
• High-temperature endurance — 3000 hours at 105°C provides predictable life under elevated operating temperatures.
• Automotive-grade qualification — AEC-Q200 rating supports selection for designs targeting automotive electronic modules.
• Through-hole mounting simplicity — Radial lead construction with standard 3.5 mm spacing facilitates conventional assembly and replacement workflows.
