UPW2G101MRD

The UPW2G101MRD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPW series designed for demanding power-filtering applications. It is a radial-lead, polarized electrolytic capacitor specified at 100 µF and 400 V, offering characteristics suited to switching power supplies and high-voltage power electronics.

With an 8000-hour endurance at 105°C and AEC-Q200 reliability rating, this part targets applications that require long-term thermal stability, predictable ripple handling, and compact through-hole packaging. Status: End Of Life.

Key Features

• Capacitance & Tolerance — 100 µF nominal capacitance with a tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated for 400 V operation, suitable for high-voltage DC-link and power-supply filtering.
• Low-loss Characteristics — Dissipation factor (tanδ) specified at 0.25 (20°C, 120 Hz), supporting low-loss filtering at mid frequencies.
• Ripple Current Capability — Low-frequency ripple current of 350 mA (120 Hz) and high-frequency ripple current of 560 mA (10 kHz), supporting dynamic filtering requirements in switching supplies.
• Leakage Current — Specified leakage current of 1700 µA, enabling predictable bias behavior after voltage application.
• High Temperature Endurance — Rated for 8000 hours at 105°C, providing long-term stability under elevated operating temperatures.
• Package & Mounting — Radial-lead can (φ22 × 50 mm) with 10 mm lead spacing (±0.5 mm); supplied in bulk/bag packing with no terminal forming.
• Automotive-Grade Reliability — Rated AEC-Q200 and explicitly listed for automotive applications in the product data.
• Operating Temperature Range — Specified for -40°C to +105°C operation.

Typical Applications

• Switching Power Supplies — Acts as a compact, high-voltage filter capacitor for primary-side DC-link and output smoothing in switching converters.
• Automotive Power Electronics — Suitable for automotive power modules and control units where AEC-Q200 qualification and elevated-temperature endurance are required.
• Power Conversion Modules — Used in inverters, DC–DC converters and other power conversion circuits requiring 400 V parts and reliable ripple handling.

Unique Advantages

• 400 V capability: Enables use in high-voltage DC-link and power-supply stages without voltage derating for many designs.
• Long-term thermal endurance: 8000 hours at 105°C reduces risk of premature aging in hot, continuously powered environments.
• Defined ripple-handling: Explicit ripple current ratings at 120 Hz and 10 kHz let designers size capacitors for both low- and high-frequency ripple conditions.
• Compact, through-hole form factor: φ22 × 50 mm radial can with 10 mm lead spacing fits legacy and serviceable board layouts while conserving board area.
• Automotive-grade qualification: AEC-Q200 rating supports designs that require recognized reliability processes and screening.
• Ready-for-assembly packaging: Bulk/bag packing with no terminal forming simplifies through-hole production workflows and service replacement.
