UPH2W470MHD

The UPH2W470MHD from Nichicon is a high-voltage, miniature-sized aluminum electrolytic capacitor in the UPH series designed for applications that require 450 V capability in a compact radial-can package. It provides a 47 µF capacitance with high ripple-current handling and a specified load life of 2000 hours at 105°C, making it suitable for demanding high-voltage power circuits and ballast applications.

Key Features

• High Voltage Rating (450 V) Rated for 450 V operation to support high-voltage circuits and power-stage applications.
• 47 µF Capacitance, ±20% Tolerance Delivers 47 µF with a tolerance of −20% to +20%, suitable for bulk filtering and energy storage at high voltage.
• High Ripple Current Rated ripple current of 430 mA at 120 Hz and 645 mA at 10 kHz, enabling robust AC ripple handling in power systems.
• Long Thermal Endurance Load life specified as 2000 hours at 105°C under DC bias plus rated ripple current for sustained high-temperature operation.
• Wide Operating Temperature Range Specified for −40°C to +105°C operation to support a broad set of environmental conditions.
• Radial Lead, Compact Package Radial lead (can) package with 5 mm lead spacing and dimensions L: 3.15 cm × D: 1.25 cm; maximum seated height 1.24 inch for space-constrained board layouts.
• RoHS Compliant Conforms to the RoHS Directive (2011/65/EU, (EU)2015/863) for restricted substances compliance.

Typical Applications

• Ballast Applications Specifically suited for ballast applications where high voltage capability and ripple tolerance are required.
• General-Purpose High-Voltage Circuits Use in general-purpose circuits that require a 450 V rated electrolytic with moderate capacitance and high ripple handling.
• Through-Hole Radial Power Assemblies Radial lead configuration and compact can package support traditional through-hole power module assemblies and retrofit designs.

Unique Advantages

• Compact high-voltage solution: 450 V rating in a miniature radial-can footprint provides high-voltage capability without large board area.
• High ripple-handling capability: 430 mA (120 Hz) and 645 mA (10 kHz) ripple ratings reduce heating and improve reliability in AC-stressed circuits.
• Extended high-temperature life: 2000 hours at 105°C load life offers predictable durability in elevated-temperature environments.
• Wide operating temperature range: −40°C to +105°C specification supports deployment across varied environmental conditions.
• RoHS compliance: Meets modern restricted-substances requirements for regulatory alignment in global designs.
• Through-hole radial packaging: Radial leads and 5 mm lead spacing simplify assembly into legacy and field-replaceable designs.
