UPS2G470MRD6

The UPS2G470MRD6 from Nichicon is a miniature, low-impedance aluminum electrolytic capacitor in the UPS series, optimized for switching power supply applications and general-purpose power filtering. It pairs a 400 V rated voltage with 47 µF capacitance in a compact radial-can package to address high-voltage bulk and decoupling needs in space-conscious designs.

Key design attributes include a polarized radial-lead package, a wide operating temperature range, and endurance rated for extended high-temperature operation, making it suitable for demanding power-electronics environments.

Key Features

• High Voltage Rating — 400 V rated voltage suitable for high-voltage DC link and bulk-filter applications.
• Capacitance and Tolerance — 47 µF nominal capacitance with ±20% tolerance to support predictable filtering behavior.
• Low Impedance — Miniature, low-impedance construction designed for switching power supplies and power-decoupling tasks.
• Ripple Current Performance — Specified ripple current: 170 mA at 120 Hz and 272 mA at 10 kHz, supporting both low- and high-frequency ripple conditions.
• Package and Mounting — Radial lead, can-style package with 1 cm lead spacing for through-hole PCB mounting and straightforward assembly.
• Wide Operating Temperature — Rated for −40 °C to +105 °C to handle a broad range of operating environments.
• Endurance — Designed for 3000 hours of operation at 105 °C, supporting long-term use at elevated temperatures.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.
• Polarized — Polarized electrolytic construction for DC applications where correct polarity is observed.

Typical Applications

• Switching Power Supplies — Bulk and decoupling capacitor for DC link and output filtering in SMPS designs.
• General-Purpose Power Filtering — Smoothing and energy storage in a wide range of industrial and electronic power circuits.
• Space-Constrained Power Designs — Compact 3.1 × 2.0 cm can and 1 cm lead spacing for installations with limited board area.
