UPW2F4R7MPD

The UPW2F4R7MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPW series, built as a radial lead can for power electronics. It provides 4.7 µF capacitance at a 315 V rating and is optimized for switching power supply and automotive electronics use.

Designed for compact power filtering and decoupling, this polarized capacitor pairs low impedance characteristics with long-term endurance for elevated-temperature operation.

Key Features

• Capacitance & Voltage — 4.7 µF nominal capacitance with a 315 V rated voltage and ±20% tolerance, suitable for high-voltage power filtering.
• Miniature radial package — Compact can with dimensions φ10 × 16 L and 5 mm lead spacing (±0.5 mm), configured as a radial lead mount for through-hole assemblies.
• Low loss (tan δ) — Specified tan δ of 0.2 measured at 20°C, 120 Hz to support low dissipation in filtering applications.
• Ripple current capability — Low-frequency ripple current 45 mA (120 Hz) and high-frequency ripple current 72 mA (10 kHz), addressing both mains-frequency and high-frequency switching ripple.
• Leakage current — Measured leakage current of 159.22 µA under specified conditions, providing predictable standby behavior in bias circuits.
• High-temperature endurance — Rated lifetime of 5000 hours at 105°C under rated voltage and ripple stress, enabling reliable operation in thermally demanding environments.
• Polarized, radial-lead construction — Standard polarized electrolytic configuration in a radial can for straightforward assembly and replacement.
• AEC-Q200 qualification — Manufactured to an AEC-Q200 rating, supporting qualification expectations for automotive electronics designs.
• Packaging options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly preparation.

Typical Applications

• Switching power supplies — Bulk and output filtering where miniature, low-impedance capacitors are required to manage switching ripple.
• Automotive electronics — Power rail decoupling and filtering in automotive modules, leveraging AEC-Q200 qualification and 105°C endurance.
• Embedded power systems — Local decoupling and energy storage on compact boards where a 315 V rating and small footprint are needed.

Unique Advantages

• Compact high-voltage solution: 315 V rating in a φ10 × 16 mm can provides a small footprint for high-voltage filtering tasks.
• Designed for switching environments: Specified ripple current at both 120 Hz and 10 kHz supports mixed-frequency filtering in switching supplies.
• Long-term thermal reliability: 5000-hour endurance at 105°C gives predictable lifetime performance in elevated-temperature installations.
• Automotive-grade qualification: AEC-Q200 rating addresses automotive reliability requirements for electronic control and power modules.
• Predictable electrical behavior: Specified tan δ and leakage current figures support precise design margining for power and standby conditions.
• Flexible supply format: Bulk or bag packing accommodates both prototype builds and higher-volume assembly processes.
