UPZ2G181MHD

The UPZ2G181MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPZ series. It is a radial-lead, polarized can-style capacitor rated at 180 µF and 400 V for general-purpose high-voltage applications.

Designed for compact assemblies that require stable performance across a wide temperature range, this part offers long-term endurance at elevated temperature and defined ripple-handling capability for power and filter circuits.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, suitable for high-voltage DC applications requiring bulk capacitance.
• Package & Mounting — Radial lead, can-style package with 7.5 mm lead spacing and dimensions of L: 4 cm × D: 1.8 cm; designed for through-hole mounting in compact boards.
• Temperature & Endurance — Operating temperature range of −40°C to +105°C with an endurance specification of 2000 hours at 105°C under rated conditions.
• Ripple Current Performance — Rated ripple current of 880 mA at 120 Hz and 1.32 A at 10 kHz (series specifications), with frequency coefficients defined for higher-frequency ripple multiplication.
• Leakage & Loss Characteristics — Leakage current characterized by the series formula (0.04·C·V + 100 µA after 1 minute at 20°C) and a maximum tan δ of 0.15 for the 400 V rating, enabling predictable loss and leakage behavior.
• Polarized, General-Purpose — Polarized electrolytic construction intended for general-purpose high-voltage applications where bulk capacitance and durability are required.

Typical Applications

• High-voltage power filtering — Bulk decoupling and smoothing in DC power circuits where 400 V rating and 180 µF capacitance are required.
• Power supply energy storage — Local energy reservoir in compact, through-hole assemblies that need reliable performance up to 105°C.
• General-purpose industrial electronics — Use in equipment requiring polarized, radial-lead capacitors with defined ripple and endurance characteristics.

Unique Advantages

• High-voltage capability: 400 V rating enables use in elevated-voltage circuits without over-specifying larger packages.
• Compact, through-hole form factor: Radial can package (L: 4 × D: 1.8 cm) and 7.5 mm lead spacing simplify PCB layout in space-constrained designs.
• Defined high-temperature endurance: Specified for 2000 hours at 105°C, providing predictable long-term behavior in hot operating environments.
• Measured ripple handling: Specified ripple currents (880 mA at 120 Hz, 1.32 A at 10 kHz) and series frequency coefficients support selection for both low- and high-frequency ripple conditions.
• Predictable leakage and dissipation: Leakage current formula and a maximum tan δ of 0.15 at 400 V make it straightforward to model losses and idle current in designs.
• Wide operating range: −40°C to +105°C rating covers a broad set of industrial and commercial environments.
