UHW1V222MHD

The UHW1V222MHD is a radial lead aluminum electrolytic capacitor from Nichicon’s UHW series. It delivers 2200 µF nominal capacitance at a 35 V rating in a compact φ12.5 × 35.5 mm can with 5 mm lead spacing.

Designed for general-purpose electronics where high ripple current, low impedance and long-term reliability are required, this part offers extended endurance (10000 hours at 105°C) and RoHS compliance.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with a rated voltage of 35 V and tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 3.09 A (120 Hz) and high-frequency ripple current of 4.12 A (10 kHz) to support demanding AC ripple conditions.
• Low Impedance — Specified impedance of 33 mΩ, supporting lower voltage drop and improved performance at higher frequencies.
• Long Endurance — Endurance rating of 10000 hours at 105°C under rated bias and ripple conditions for extended in-service life.
• Leakage and Dissipation — Leakage current specified at 770 µA and tan δ (DF) of 0.13 measured at 20°C, 120 Hz, enabling predictable loss behavior.
• Temperature Range — Operating from −40°C to +105°C to cover a broad set of environmental conditions.
• Compact Radial Package — φ12.5 × 35.5 mm can with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing; standard radial lead mounting for through-hole assembly.
• Regulatory — RoHS compliant as specified for the UHW series.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple handling for a wide range of electronic power circuits where polarized electrolytic capacitors are used.
• Energy storage and smoothing — Acts as a compact energy reservoir and smoothing element in DC systems operating up to 35 V.
• High-ripple environments — Suited to circuits that encounter significant AC ripple across the capacitor due to its specified LF and HF ripple current ratings.

Unique Advantages

• High ripple capability: Specified 3.09 A (120 Hz) and 4.12 A (10 kHz) ripple currents reduce temperature rise and extend component life in AC-loaded circuits.
• Low impedance at operating frequencies: 33 mΩ impedance helps reduce voltage drop and improves transient response in power rails.
• Extended high-temperature endurance: 10000 hours at 105°C provides design confidence for long-term deployments.
• Compact radial form factor: φ12.5 × 35.5 mm can with standard 5 mm lead spacing offers a space-efficient through-hole solution for PCB designs.
• Predictable leakage and dissipation: Leakage current (770 µA) and tan δ (0.13 at 20°C, 120 Hz) enable reliable thermal and loss budgeting.
• RoHS compliant: Meets the series’ RoHS directive compliance for regulatory needs.
