UBT2A221MHD8

The UBT2A221MHD8 is a radial-leaded aluminum electrolytic capacitor in Nichicon’s UBT series designed for high-temperature, heavy-duty applications. It provides 220 µF capacitance at 100 V with polarized radial can packaging (φ16 × 25 mm) and is produced for volume deployment.

Engineered for demanding environments, this capacitor targets automotive and other high-reliability electronics where elevated temperature endurance, high ripple handling, and AEC‑Q200 qualification are required.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with ±20% tolerance rated for 100 V DC operation, suitable for higher-voltage bus and filter designs.
• High‑Temperature Endurance — Rated operating temperature range of −40 °C to +125 °C with a guaranteed load life of 5000 hours at 125 °C for the specified conditions.
• Ripple Current Performance — Handles 1.005 A at 120 Hz (low frequency) and 1.5 A at 100 kHz (high frequency), enabling effective smoothing of both low- and high-frequency ripple components.
• Leakage and Impedance — Specified leakage current of 660 µA and an impedance of 110 mΩ, supporting stable performance in DC bus and decoupling applications.
• Robust Mechanical Package — Radial can package (φ16 × 25 mm) with 7.5 mm lead spacing (±0.5 mm tolerance) in a polar, through‑hole form factor for standard PCB mounting and secure mechanical retention.
• Automotive Qualification and Compliance — AEC‑Q200 qualified and RoHS compliant, aligning with automotive-grade reliability requirements and environmental regulations.
• Packaging and Availability — Supplied in bulk or bag packing with mass‑production status for supply continuity in production programs.

Typical Applications

• Automotive Electronics — Suited for automobile electronics where heavy-duty service and elevated temperature endurance are required, such as power rails and control modules.
• Power Supply Filtering — Used for bulk smoothing and DC bus decoupling at higher voltages and temperatures thanks to 220 µF/100 V rating and robust ripple current capability.
• Industrial Control Systems — Applicable in industrial power electronics that demand long life at elevated temperatures and reliable ripple handling.

Unique Advantages

• High-temperature reliability: 5000‑hour endurance at 125 °C provides predictable lifetime performance in hot operating environments.
• High-voltage capability: 100 V rating enables use on higher-voltage rails without the need for series arrangements, simplifying BOM and layout.
• Dual-frequency ripple handling: Rated ripple currents at both 120 Hz and 100 kHz support mixed-frequency power systems and switching regulator outputs.
• Automotive-grade qualification: AEC‑Q200 qualification offers design confidence for automotive and other high-reliability programs.
• Compact radial form factor: φ16 × 25 mm can with 7.5 mm lead spacing provides a space-efficient, robust through‑hole mounting solution.
• Regulatory compliance: RoHS compliance supports environmental and manufacturing requirements.
