Key Features

• Capacitance & Voltage: 170 µF nominal capacitance with ±20% tolerance at 450 V rating, providing high DC energy storage for high-voltage circuits.
• High Ripple Current Capability: Rated ripple current of 1.76 A at 120 Hz and 2.816 A at 100 kHz to support heavy AC/rectified ripple conditions in power conversion stages.
• Long Life at High Temperature: 5000 hours life specified at 105°C under rated DC bias plus rated ripple current for sustained high-temperature operation.
• Leakage Performance: Specified leakage current of 3160 µA (measurement condition per product data), enabling predictable self-discharge characteristics in high-voltage designs.
• Automotive-Grade Qualification: AEC-Q200 qualified and explicitly cited for automotive applications, including on-board chargers.
• Robust Mechanical & Mounting Package: Radial can package, φ18×50 mm case, 7.5 mm lead spacing and radial leads for straightforward through-hole assembly; supplied in bulk/no terminal forming or tray packing for mass production.
• Environmental Compliance: RoHS compliant.

Typical Applications

• Electric vehicle on-board chargers: High-voltage 450 V rating and high ripple-current capability make the UTF2W171MND suitable for DC link and smoothing stages in on-board charging systems.
• Automotive power electronics: AEC-Q200 qualification and 5000-hour endurance at 105°C support use in automotive power modules and converters.
• High-voltage power conversion: Use in DC link, inverter and high-voltage power supply applications where sustained ripple handling and thermal endurance are required.

Unique Advantages
