UPW1V331MPD

The UPW1V331MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPW series, designed for compact power applications. It is a polarized, low-impedance capacitor specified at 330 µF and 35 V, optimized for switching power supplies and other power-filtering roles.

Key design attributes include a miniature φ10 × 16L can, robust operating range of −55 °C to 105 °C, and a rated endurance of 5000 hours at 105 °C. The part is AEC-Q200 qualified and is available in mass-production quantities with bulk or bag packing.

Key Features

• Capacitance and Voltage: 330 µF nominal capacitance with a rated voltage of 35 V and capacitance tolerance of −20% to +20%.
• Low Loss and Low Impedance: tanδ of 0.12 measured at 20 °C, 120 Hz and an impedance of 136 mΩ, supporting efficient filtering and decoupling in power circuits.
• Ripple Current Handling: Low-frequency ripple current of 682.5 mA at 120 Hz and high-frequency ripple current of 1.05 A at 10 kHz, enabling effective smoothing across a range of switching frequencies.
• Leakage Current: Specified leakage current of 346.5 µA after rated voltage application, useful for predictable standby and hold-up behavior.
• Thermal and Lifetime Performance: Operating temperature range −55 °C to 105 °C with a life/endurance rating of 5000 hours at 105 °C.
• Mechanical and Mounting: Radial lead package (φ10 × 16L) with 5 mm lead spacing (±0.5 mm) for through-hole mounting and compact board placement.
• Automotive-Grade Qualification: AEC-Q200 rating for applications requiring industry-recognized reliability standards.

Typical Applications

• Switching Power Supplies: Bulk and output filtering where low impedance and high ripple-current capability are required to stabilize voltage rails.
• DC-DC Converters: Input and output decoupling to improve transient response and reduce voltage ripple in compact power modules.
• Automotive Electronics: Power smoothing and filtering in automotive control modules and infotainment systems that leverage the part's AEC-Q200 qualification and wide temperature range.
• Embedded Power Systems: Local energy storage and decoupling on boards where a small footprint (φ10 × 16L) and through-hole mounting are preferred.

Unique Advantages

• Compact, high-capacitance package: 330 µF in a φ10 × 16L can reduces board area while providing substantial energy storage for power rails.
• Predictable thermal endurance: Rated for 5000 hours at 105 °C, enabling designers to budget lifetime performance under elevated operating temperatures.
• Broad ripple frequency coverage: Specified ripple current at both low (120 Hz) and high (10 kHz) frequencies supports a wide range of switching regulator topologies.
• Low impedance and controlled loss: 136 mΩ impedance and tanδ = 0.12 at 20 °C, 120 Hz reduce heating and improve filtration efficiency.
• Automotive-capable qualification: AEC-Q200 rating provides an added level of reliability assurance for demanding environments.
• Production-ready packaging: Available in bulk (no terminal forming) or bag packing for flexible assembly and procurement needs.
