UHW1H222MHD

The UHW1H222MHD is a radial lead aluminum electrolytic capacitor in Nichicon’s UHW series, offering 2200 µF capacitance at a 50 V rating. It combines a compact φ16 × 30.5 mm can with radial-lead mounting for general-purpose power and filtering applications.

Designed for high ripple environments and extended operation, the part delivers low impedance (57 mΩ) and high ripple current capability (2.572 A at 120 Hz; 3.43 A at 10 kHz) with an endurance rating of 10,000 hours at 105°C. The component is RoHS compliant and available in bulk/bag packing for production use.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with ±20% tolerance, rated for 50 V DC.
• High Ripple Current — Low-frequency ripple current 2.572 A at 120 Hz and high-frequency ripple current 3.43 A at 10 kHz to support demanding power smoothing and decoupling tasks.
• Low Impedance — Measured impedance of 57 mΩ, helping reduce voltage ripple and heat generation in power systems.
• Thermal and Endurance Performance — Specified operating range −40°C to +105°C with a rated lifetime of 10,000 hours at 105°C under DC bias plus rated ripple current.
• Loss Characteristics — tanδ = 0.12 (measured at 20°C, 120 Hz), with datasheet guidance for larger capacitances.
• Mechanical & Mounting — Radial lead can, size φ16 × 30.5 mm, lead spacing 7.5 mm (±0.5 mm) and lead diameter 0.8 mm per series radial-lead table, suitable for through-hole PCB assembly.
• Leakage Current — Specified leakage current of 1100 µA (measured after standard application conditions).
• Packaging & Availability — Supplied in bulk (no terminal forming) / bag packing; current status: mass production.
• Regulatory — RoHS compliant.

Typical Applications

• Power Supply Smoothing — Bulk energy storage and output filtering for DC power supplies where 2200 µF and 50 V are required to reduce ripple and stabilize rails.
• DC-DC Converters — Input/output decoupling and energy buffering in converters that demand high ripple current capability and low impedance.
• Industrial Electronics — General-purpose filtering and bulk capacitance in control equipment and power modules operating across −40°C to +105°C.

Unique Advantages

• Compact radial package: φ16 × 30.5 mm can provides 2200 µF capacitance in a small through-hole footprint to save PCB area.
• High ripple handling: Rated ripple currents of 2.572 A (120 Hz) and 3.43 A (10 kHz) reduce temperature rise under AC stress, extending component life in power applications.
• Low impedance: 57 mΩ impedance helps minimize voltage drop and improves transient response in power delivery circuits.
• Long endurance at elevated temperature: 10,000-hour rating at 105°C supports long-term reliability in thermal-stressed environments.
• Wide operating temperature: −40°C to +105°C allows deployment across a broad range of ambient conditions.
• Production-ready packaging: Bulk/bag packing and mass-production status simplify procurement and BOM planning.
