UPT2G181MRD

The UPT2G181MRD is a miniature aluminum electrolytic capacitor from Nichicon's UPT series, designed for high ripple current and long-life applications. It is a polarized, radial‑lead, can‑style capacitor with a 180 µF capacitance at a 400 V rating.

Targeted for general-purpose and ballast applications, this part delivers high ripple handling and reliable performance across a wide temperature range, making it suitable for high-voltage filtering and energy storage in compact designs.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance rated at 400 V with ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Current — Rated ripple current of 850 mA at 120 Hz (105°C) and 1.36 A at 10 kHz, supporting applications with significant AC ripple stress.
• Long Life & Endurance — Specified lifetime of 5000 hours at 105°C under D.C. bias plus rated ripple current; after endurance testing capacitance stays within ±20% and leakage/ta n δ remain within specified limits.
• Wide Operating Temperature — Rated for −40°C to +105°C operation to accommodate a broad range of environmental conditions.
• Compact Radial Package — Radial, can-style package with lead spacing of 1.0 cm and dimensions L: 4.0 cm × D: 2.2 cm for space‑constrained layouts.
• Polarized, General‑Purpose Design — Polarized aluminum electrolytic construction suited for common high-voltage DC smoothing and ballast uses.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• Ballast circuits — Suited for ballast application where high ripple current capability and stable high-voltage capacitance are required.
• High‑voltage power filtering — Provides bulk energy storage and smoothing in 400 V DC bus and high-voltage filter stages.
• High‑ripple environments — Used where sustained ripple current is present, leveraging its specified ripple current ratings at 120 Hz and 10 kHz.

Unique Advantages

• High ripple handling: Rated ripple current of 850 mA (120 Hz) and 1.36 A (10 kHz) reduces thermal stress in ripple‑heavy circuits.
• Long operational life: 5000 hours at 105°C under rated conditions supports extended maintenance intervals and predictable end‑of‑life behavior.
• Compact footprint: 4.0 cm × 2.2 cm can size and radial lead format help save board space while keeping installation straightforward.
• Wide temperature range: −40°C to +105°C rating maintains capacitance performance across a broad thermal envelope.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for electronic assemblies.
