UPW2G4R7MPD

The UPW2G4R7MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPW series, supplied in a radial-lead can (φ10×20L) with 5 mm lead spacing. It delivers 4.7 µF capacitance at a 400 V rating and is specified for demanding power applications that require compact high-voltage filtering and energy storage.

Designed with switching power supplies and automotive-grade designs in mind, the part combines a defined loss tangent, controlled leakage, ripple current capability at both low and high frequencies, and endurance performance up to 5000 hours at 105 °C.

Key Features

• Capacitance & Voltage — 4.7 µF nominal capacitance with a rated voltage of 400 V and a tolerance of -20% to +20%.
• Miniature radial package — φ10×20L aluminum can with radial leads and 5 mm lead spacing (±0.5 mm), suitable for compact through-hole layouts.
• High-temperature endurance — Endurance rated to 5000 hours at 105 °C under specified DC bias plus rated ripple conditions.
• Defined electrical loss — tanδ (dissipation factor) specified at 0.25 (measured at 20 °C, 120 Hz), enabling predictable AC loss behavior in designs.
• Ripple and leakage performance — Low-frequency ripple current: 43 mA (120 Hz); high-frequency ripple current: 68.8 mA (10 kHz); leakage current: 175.2 µA.
• Polarized, radial-lead mounting — Polarized device intended for radial through-hole mounting; available in bulk (no terminal forming) or bag packing.
• AEC-Q200 qualification — Rated with AEC-Q200, indicating suitability for electronics requiring that qualification level.

Typical Applications

• Switching power supplies — Compact high-voltage filtering and decoupling where small form factor and defined loss/ leakage are required.
• Power electronics in automotive systems — AEC-Q200 rating, -40 °C to 105 °C operating range, and 5000 h endurance at 105 °C make it applicable for automotive-grade power circuits.
• DC link and energy storage — 400 V rating and measurable ripple-current capability support mid-voltage DC link filtering and pulse-energy smoothing.

Unique Advantages

• Compact high-voltage capability: 400 V rating in a φ10×20 radial can saves board area while supporting higher-voltage designs.
• Predictable AC and leakage behavior: Specified tanδ, ripple currents at 120 Hz and 10 kHz, and measured leakage current provide engineering-grade parameters for thermal and reliability analysis.
• Long endurance at elevated temperature: 5000 hours at 105 °C supports sustained operation in thermally demanding environments.
• Automotive-grade qualification: AEC-Q200 rating supports use in designs targeting automotive-system requirements.
• Mounting flexibility and packaging: Radial-lead can format with standard 5 mm lead spacing and bulk or bag packing options simplifies procurement and assembly for through-hole processes.
