UPW2W220MHD

The UPW2W220MHD is a miniature, high‑reliability radial‑lead aluminum electrolytic capacitor from Nichicon's UPW series. Designed for demanding power electronics, it combines a 450 V rated voltage with compact radial can packaging for use where high voltage handling and long life are required.

Its specification set—low impedance characteristics for switching power supplies, AEC‑Q200 rating, and extended endurance at elevated temperature—makes it suited to applications that demand stable smoothing and ripple handling over long operational lifetimes.

Key Features

• Rated Voltage — 450 V High working voltage capability for high‑voltage power rails and power conversion stages.
• Capacitance & Tolerance 22 µF nominal capacitance with tolerance of −20% to +20% for predictable bulk energy storage (as specified).
• Low Loss (tan δ) tanδ = 0.25 (measured at 20°C, 120 Hz), supporting low dissipation in AC ripple environments.
• Ripple Handling Low‑frequency ripple current 115 mA at 120 Hz and high‑frequency ripple current 184 mA at 10 kHz for effective smoothing across frequencies.
• Leakage Current Specified leakage current of 496 µA for predictable bias current in DC applications.
• Long Endurance Rated life of 8000 hours at 105°C, providing extended service in elevated‑temperature environments.
• Mechanical & Mounting Radial‑lead can, size φ16 × 30.5 L (L: 3.05 × D: 1.6 cm), with 7.5 mm lead spacing (±0.5 mm) for standard through‑hole PCB layouts.
• Qualification AEC‑Q200 listed, indicating suitability for designs requiring industry automotive qualification standards.
• Packaging Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.

Typical Applications

• Switching Power Supplies — Miniature, low‑impedance construction tailored for smoothing and ripple suppression in switching regulators and power modules.
• Automotive Electronic Systems — AEC‑Q200 rating and extended high‑temperature endurance support use in automotive electronic control units and power electronics.
