UPW1E331MPD6

The UPW1E331MPD6 is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series, sized φ8 × 15 mm with polarized, through-hole construction. It delivers 330 µF capacitance at a 25 V rating with low impedance and engineered reliability for power conditioning in compact electronic systems.

Targeted for power-supply smoothing and decoupling in demanding environments, this part combines a wide operating temperature range and a long endurance rating to support sustained ripple handling in compact form factors.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a 25 V rated voltage with ±20% tolerance, providing bulk energy storage and decoupling for low-voltage rails.
• Low Impedance — Specified impedance of 170 mΩ, supporting effective high-frequency smoothing and reduced voltage ripple in switching power circuits.
• Loss Characteristics — tanδ = 0.14 measured at 20°C and 120 Hz, enabling predictable AC performance for filtering applications.
• Ripple Current Capability — 474.5 mA at 120 Hz (low frequency) and 730 mA at 10 kHz (high frequency), supporting continuous ripple handling across common switching frequencies.
• Leakage Current — 247.5 µA leakage current, suitable for power circuits where low DC leakage is required.
• High-Temperature Endurance — Rated life of 3000 hours at 105°C, designed for sustained operation in elevated-temperature environments.
• Wide Temperature Range — Operational from −55°C to +105°C for broad environmental tolerance.
• Automotive-Grade Reliability — AEC-Q200 rated, providing a qualification level suitable for automotive and other high-reliability applications.
• Package & Mounting — Radial lead, can-style package with φ8 × 15 mm dimensions, 3.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible assembly workflows.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling where low impedance and high ripple capability reduce voltage ripple and improve regulator stability.
• Automotive Electronics — Power-filtering and energy storage in vehicle subsystems, leveraging the AEC-Q200 rating and wide temperature range.
• Embedded Power Modules — Local energy reservoir for DC–DC converters and power management modules in compact, through-hole designs.

Unique Advantages

• Compact energy density — 330 µF in a φ8 × 15 mm can provides substantial capacitance for space-constrained boards.
• Measured low impedance — 170 mΩ supports improved transient response and reduced ripple compared to higher-impedance parts.
• Frequency-capable ripple performance — Defined ripple current ratings at both 120 Hz and 10 kHz ensure predictable behavior across typical switching frequencies.
• Thermal endurance — 3000-hour rating at 105°C provides longevity for designs exposed to elevated operating temperatures.
• Automotive qualification — AEC-Q200 rating supports use in designs requiring recognized component-level reliability standards.
• Through-hole simplicity — Radial-lead format with common lead spacing simplifies board-level prototyping and replacement in legacy or serviceable designs.
