UBY2A271MHL

The UBY2A271MHL is a high-reliability miniature aluminum electrolytic capacitor from Nichicon's UBY series, configured as a radial-lead can. It delivers 270 µF capacitance at a 100 V rating with polarized construction and is designed for high-temperature applications.

Targeted at demanding control electronics, this part offers high ripple-current capability, low impedance, and AEC-Q200 qualification—making it suitable for automobile control circuits and other high-temperature, high-reliability systems.

Key Features

• Capacitance & tolerance — 270 µF nominal with tolerance of -20% to +20% at 120 Hz, 20°C.
• Voltage rating — 100 V rated voltage for high-voltage DC applications.
• Low impedance / loss — tanδ (DF) 0.08 measured at 20°C, 120 Hz; ESR 53 mΩ measured at 20°C/100 kHz for low-loss performance.
• High ripple-current handling — 955 mA at 120 Hz (low frequency) and 1.91 A at 100 kHz (high frequency) to support power filtering and transient loads.
• Thermal and endurance — Operating temperature range -40°C to 135°C; endurance specified as 2000 hours at 135°C for 63–100 V parts.
• Leakage current — Specified leakage current of 810 µA.
• Package & mounting — Radial can, dimensions φ16 × 20 L, lead spacing 7.5 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Qualification — AEC-Q200 rated, suitable for applications requiring standardized reliability qualification.

Typical Applications

• Automobile control circuits — Suited for automotive control modules including systems such as electric power steering and direct injection engine drive where high ripple handling and high-temperature endurance are required.
• High-temperature power electronics — Filtering and decoupling in electronics designed to operate at elevated ambient temperatures up to 135°C.
• Engine control units (ECUs) — Bulk energy storage and smoothing in vehicle ECUs that demand AEC-Q200-qualified components and robust ripple performance.

Unique Advantages

• High ripple capability: Rated ripple currents of 955 mA (120 Hz) and 1.91 A (100 kHz) support heavy AC loading and transient suppression in power circuits.
• Low ESR at high frequency: 53 mΩ ESR at 100 kHz reduces heat generation and improves efficiency in switching and high-frequency applications.
• High-temperature endurance: Rated to operate from -40°C to 135°C with a 2000-hour endurance at 135°C for 63–100 V parts, enabling reliable performance in hot environments.
• AEC-Q200 qualification: Provides standardized reliability assurance for applications that require automotive-level qualification.
• Compact radial package: φ16 × 20 L can with 7.5 mm lead spacing offers a space-efficient, through-hole mounting option for high-reliability designs.
• Manufacturer pedigree: Part of Nichicon's UBY family, designed for higher capacitance and ripple current performance within the series.
