UPT2W470MHD

The UPT2W470MHD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's UPT series. It delivers 47 µF of capacitance at a 450 V rating in a compact can-style package optimized for applications that require high ripple handling and long operational life.

Designed for general-purpose high-voltage power circuits and suited for ballast applications, the UPT2W470MHD combines elevated ripple-current capability with a long endurance rating at elevated temperature to support reliable performance in constrained footprints.

Key Features

• Capacitance and Voltage — 47 µF nominal capacitance at a 450 V rated voltage with ±20% tolerance (−20% to +20%).
• High Ripple Current — Rated ripple current: 380 mA at 120 Hz and 608 mA at 10 kHz, providing robust AC performance for demanding power circuits.
• Long Life at Elevated Temperature — Endurance specified as 5000 hours at 105°C when DC bias plus rated ripple current are applied; capacitance change remains within ±20% after test.
• Wide Operating Temperature Range — Specified from −40°C to +105°C for use across varied thermal environments.
• Compact Radial Can Package — Radial lead mounting with 7.5 mm lead spacing; physical size L: 3.05 cm × D: 1.6 cm and a maximum seated height of 1.201 inch, enabling space-efficient PCB layouts.
• Low Leakage Current Specification — Leakage current defined as not more than 0.06CV + 10 µA after 2 minutes at 20°C, supporting predictable quiescent behavior.
• Polarized — Designed for polarized DC applications.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• Ballasts — Suited for ballast applications that require high ripple handling and reliable life at elevated temperatures.
• General‑Purpose High‑Voltage Power Circuits — For circuits that need 450 V rated capacitance in a compact radial package.
• Space‑Constrained Designs — Compact L×D footprint and radial-can form factor for designs where PCB real estate is limited.

Unique Advantages

• High AC Stress Tolerance: Explicit ripple ratings at both 120 Hz (380 mA) and 10 kHz (608 mA) make the part suitable where elevated ripple currents are present.
• Proven Endurance: 5000 hours at 105°C under DC bias plus rated ripple current—specifications for capacitance, tan δ and leakage current are maintained after the endurance test.
• Predictable Leakage Performance: Leakage defined by the measurable formula 0.06CV + 10 µA (after 2 minutes at 20°C), enabling predictable designs for standby and bias conditions.
• Compact Form Factor: Small L: 3.05 cm × D: 1.6 cm radial can with 7.5 mm lead spacing supports dense board placement without sacrificing voltage rating.
• Regulatory Compliance: RoHS conformity supports deployment in regulated markets.
