UPW2G100MHD

The UPW2G100MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPW series, configured as a radial lead device. It delivers 100 µF capacitance at a 400 V rating and is designed for applications that require compact energy storage and filtering at elevated voltages.

Built for switching power supplies and high-voltage electronics, the UPW2G100MHD pairs a compact φ12.5 × 25 mm can with measurable electrical performance (low-frequency and high-frequency ripple handling, defined leakage, and loss tangent), making it suitable for demanding power-filtering roles.

Key Features

• Capacitance & Tolerance — 100 µF rated capacitance with tolerance of -20% to +20% for predictable energy storage and selection.
• High Voltage Rating — 400 V rated voltage suitable for high-voltage DC rails and power conversion environments.
• Thermal Performance & Lifetime — Operating temperature range of -40°C to +105°C and rated endurance of 7000 hours at 105°C.
• Ripple and Leakage Characteristics — Low-frequency ripple current 72 mA (120 Hz), high-frequency ripple current 115.2 mA (10 kHz), and leakage current specified at 260 µA.
• Electrical Loss — tan δ = 0.25 (measured at 20°C, 120 Hz), supporting predictable dissipation behavior in AC/ripple conditions.
• Package & Mechanical — Radial lead (can) package with dimensions φ12.5 × 25 mm and 5.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing.
• Series Characteristics — UPW series: miniature-sized, low impedance, high reliability for switching power supplies (series-level characteristic).
• Qualification — AEC-Q200 rating specified in product data, supporting use in automotive-grade ecosystems where that qualification is required.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where compact, low-impedance capacitors are required for ripple attenuation in high-voltage supplies.
• Automotive Electronics — Energy storage and smoothing on high-voltage automotive subsystems where AEC-Q200 qualification is required.
• High-Voltage DC Filtering — Filtering and decoupling on 400 V DC rails or similar high-voltage power conversion stages.

Unique Advantages

• 400 V Rating for High-Voltage Designs: Enables direct deployment on high-voltage DC rails without additional series components.
• Compact Radial Can: φ12.5 × 25 mm package offers a small footprint for space-constrained power boards while maintaining adequate capacitance.
• Long Endurance at Elevated Temperature: 7000 hours at 105°C supports extended service life in thermally demanding environments.
• Measured Ripple and Leakage Specs: Explicit low- and high-frequency ripple current ratings and a defined leakage current (260 µA) simplify thermal and reliability calculations.
• AEC-Q200 Qualification: Product data lists AEC-Q200, providing a qualification pathway for automotive-grade system designs.
