The UPW1C331MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series, optimized for miniature, low-impedance, high-reliability power applications. This 330 µF, 16 V polarized capacitor is designed for use in compact switching power supplies and automotive electronics where space, ripple handling and thermal endurance are important.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of -20% to +20%.
• Low Impedance Performance — Specified impedance of 234 mΩ and tanδ of 0.16 (measured at 20°C, 120 Hz) for effective decoupling and smoothing in power rails.
• Ripple Current Capability — Low-frequency ripple current 360.8 mA (120 Hz) and high-frequency ripple current 555 mA (10 kHz), supporting dynamic load conditions.
• Reliability & Endurance — Rated for 3000 hours at 105°C; leakage current specified at 158.4 µA after initial application of rated voltage.
• Wide Temperature Range — Operates between -55°C and +105°C for use across harsh thermal environments.
• Compact Radial Package — Small can size φ8 × 11.5 mm length with 3.5 mm lead spacing (±0.5 mm), sold in bulk or bag packing for flexible assembly options.
• AEC-Q200 Rated — Built to an AEC-rated specification, supporting automotive product development and high-reliability applications.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple current capability make this capacitor suitable for input/output smoothing and energy buffering in compact switch-mode supplies.
• Automotive Electronics — AEC-Q200 rating and extended temperature range support deployment in vehicle electronic modules and control systems.
• Compact Power Circuits — Miniature φ8 can and radial-lead format are suitable for space-constrained power and control boards requiring reliable bulk capacitance.

Unique Advantages

• Space-efficient bulk capacitance — 330 µF in a φ8 × 11.5 mm can provides substantial charge storage in a small footprint, helping reduce board area.
• Measurable low-loss operation — Tan δ of 0.16 (20°C, 120 Hz) and defined impedance support predictable AC performance in filter and decoupling roles.
• Designed for ripple stress — Specified ripple currents at low and high frequencies allow designers to size capacitors with confidence under dynamic loads.
• Thermal endurance for demanding environments — 3000-hour life rating at 105°C and -55°C to +105°C operating range enable longer service life in elevated-temperature applications.
• Automotive-capable construction — AEC-Q200 rating provides a documented qualification baseline for use in automotive electronics programs.
• Production-ready packaging — Available in bulk or bag packing and listed as mass production, simplifying sourcing for volume designs.
