UPS2G220MHD

The UPS2G220MHD is a miniature aluminum electrolytic capacitor from Nichicon's UPS series, designed for switching power supplies and general-purpose power filtering. It combines a 22 µF capacitance with a 400 V rated voltage in a low-impedance, radial-lead can suitable for through-hole mounting.

Engineered for reliability under elevated temperature, the UPS2G220MHD offers long-term endurance and RoHS compliance, making it applicable for industrial and power-electronics designs that require compact high-voltage capacitance.

Key Features

• Electrical Performance — 22 µF capacitance with a 400 V rated voltage and ±20% tolerance, providing a compact high-voltage energy-storage element for power rails and filtering.
• Low Impedance for Switching Supplies — Designed as a low-impedance, miniature type suitable for switching power supply applications to support stable ripple handling.
• Ripple Current Capability — Rated ripple current of 110 mA at 120 Hz and 176 mA at 10 kHz, enabling effective smoothing in AC and high-frequency environments.
• Thermal Endurance — Rated operating range from −40 °C to 105 °C and lifetime of 3000 hours at 105 °C, supporting sustained operation in elevated-temperature conditions.
• Polarized, Through-Hole Package — Polarized radial-lead construction in a radial can (L: 2.5 × D: 1.6 cm) with 7.5 mm lead spacing for reliable through-hole mounting and straightforward PCB placement.
• Regulatory Compliance — RoHS compliant to support environmentally restricted designs.

Typical Applications

• Switching Power Supplies — Used for output smoothing and decoupling where low impedance and high-voltage rating are required.
• Power Rail Filtering — Provides bulk and high-frequency ripple suppression on DC rails in converters and power modules.
• Industrial Control Electronics — Suited for general-purpose filtering in industrial power systems that demand elevated-temperature endurance.
• Through-Hole Power Assemblies — Radial lead package makes it suitable for through-hole assemblies and serviceable power boards.
