UBW2A221MHD

The UBW2A221MHD is a Nichicon UBW-series aluminum electrolytic capacitor in a radial-lead can. It delivers 220 µF at a 100 V rating in a compact φ16 × 25 mm package with 7.5 mm lead spacing, designed for high-temperature, long-life applications.

Engineered for demanding environments, this radial-type capacitor offers a wide operating temperature range to +135°C, an endurance rating of 3000 hours at 135°C, and AEC‑Q200 qualification for use in applications requiring elevated reliability.

Key Features

• Electrical Performance — 220 µF capacitance at 100 V rated voltage with ±20% tolerance for energy storage, decoupling and filtering tasks.
• Low Loss / Impedance — tanδ 0.08 (measured at 20°C, 120 Hz, 100 V) and specified impedance of 110 mΩ to help minimize dissipation in power applications.
• Ripple Current Capability — Rated low-frequency ripple current 1.005 A (120 Hz) and high-frequency ripple current 1.5 A (10 kHz) for robust handling of both line- and switching-induced ripple.
• High-Temperature Endurance — Operates from −55°C to +135°C with a demonstrated life of 3000 hours at 135°C under rated conditions.
• Leakage Current — Specified leakage current of 660 µA for predictable standby and bias current behavior.
• Mechanical & Packaging — Radial lead, can-style package (φ16 × 25 mm, lead spacing 7.5 mm) with bulk or bag packing; delivered in mass-production status.
• Automotive-Grade Qualification — AEC‑Q200 rating to support use in automotive and other high-reliability systems.

Typical Applications

• Automotive Power Electronics — Smoothing and bulk energy storage on 100 V rails where AEC‑Q200 qualification and +135°C capability are required.
• Industrial Control — DC link and power-supply filtering in industrial converters and drives that demand long life at elevated temperatures.
• Power Supply Filtering — Decoupling and ripple attenuation for high-voltage supplies, leveraging the specified ripple current ratings and low impedance.

Unique Advantages

• High-temperature endurance: 3000 hours at 135°C provides predictable long-term performance in hot environments.
• Automotive-capable: AEC‑Q200 qualification enables integration into transportation and other high-reliability designs.
• Balanced ripple handling: Defined ripple current at both 120 Hz and 10 kHz supports mixed-frequency power systems and switching supplies.
• Compact radial form factor: φ16 × 25 mm can with 7.5 mm lead spacing simplifies board layout for through-hole assemblies.
• Clear electrical characterization: Specified tanδ, impedance and leakage current values allow engineers to model losses and idle currents precisely.
