UVZ2W220MHD

The UVZ2W220MHD is a Nichicon UVZ series aluminum electrolytic capacitor in a radial-lead can, rated 22 µF at 450 V. It is designed for general-purpose applications that require a compact, high-voltage electrolytic solution with defined endurance and temperature performance.

Key value comes from its 450 V rating, wide operating range to 105°C, and a 2000-hour endurance at 105°C, making it suitable for designs that need stable capacitance, controlled dissipation factor, and predictable ripple handling over time.

Key Features

• Rated Voltage — 450 V nominal rating for high-voltage applications where elevated working voltage is required.
• Capacitance and Tolerance — 22 µF with tolerance of -20% to +20%, specified at 20°C and 120 Hz for predictable design margins.
• Dissipation Factor (tan δ) — tanδ 0.25 (measured at 20°C, 120 Hz), enabling designers to account for loss characteristics in thermal and ripple budgets.
• Ripple Current Capability — Low-frequency ripple current 115 mA (120 Hz) and high-frequency ripple current 184 mA (10 kHz), specified to help size thermal and longevity margins under varying switching conditions.
• Leakage Current — Specified leakage current of 496 µA after rated voltage application, supporting predictable quiescent current planning.
• Endurance / Lifetime — 2000 hours life rating at 105°C with rated voltage applied, enabling long-term performance planning in elevated-temperature environments.
• Operating Temperature — -25°C to +105°C operating range for applications requiring extended temperature operation at the 450 V rating.
• Package and Mounting — Radial lead can, size φ16 × 25L (16 mm diameter, 25 mm length) with 7.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB layouts.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to accommodate different assembly and handling preferences.
• Compliance — RoHS compliant as stated in the product data.

Typical Applications

• General-purpose power circuits — Used where a 450 V, 22 µF electrolytic capacitor is required for bulk capacitance or DC link smoothing in general-purpose designs.
• Power supply filtering — Provides decoupling and smoothing in high-voltage power supplies that operate within the -25°C to 105°C range.
• Industrial and commercial equipment — Suitable for equipment requiring a defined endurance (2000 h at 105°C) and stable leakage/ripple characteristics.

Unique Advantages

• High-voltage capability: 450 V rating allows use in higher-voltage circuits without upsizing the capacitor footprint.
• Defined high-temperature endurance: 2000 hours at 105°C gives predictable longevity when designing for extended elevated-temperature operation.
• Frequency-aware ripple specs: Separate ripple-current figures for 120 Hz and 10 kHz help designers account for both low-frequency and high-frequency stress.
• Compact radial package: φ16 × 25L can with 7.5 mm lead spacing supports through-hole layouts where board space and lead spacing predictability matter.
• Controlled dissipation and leakage: Specified tanδ and leakage current enable tighter thermal and standby current calculations.
• RoHS compliant and production-ready: Mass-production status and RoHS compliance support volume sourcing and regulatory alignment.
