UCY2C151MHD3

The UCY2C151MHD3 from Nichicon is a radial-lead aluminum electrolytic capacitor in the UCY series, offering 150 µF capacitance at a 160 V rating. It combines compact, miniature can packaging (φ16 × 20 mm) with high ripple current capability and long life for demanding power applications.

Designed for applications that require reliable DC bias performance across a wide temperature range, this polarized capacitor is AEC-Q200 qualified and RoHS compliant, making it suitable for automotive and industrial power-supply environments.

Key Features

• Capacitance & Voltage: 150 µF rated at 160 V for energy storage and smoothing in medium-voltage power rails.
• Radial Lead Package: Miniature radial can (φ16 × 20 mm) with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and robust mechanical retention.
• High Ripple Current: 945 mA at 120 Hz (low frequency) and 1.89 A at 100 kHz (high frequency), supporting higher AC load currents in switching power supplies and converters.
• Long Endurance: Rated life of 10,000 hours at 105°C under specified conditions for extended service in thermal stress environments.
• Low Loss & Leakage: tanδ 0.20 (measured at 20°C, 120 Hz) with a typical leakage current of 1,060 µA after 1 minute at rated voltage, consistent with JIS/JEC test conditions.
• Temperature Range & Reliability: Operates from −40°C to +105°C and meets AEC-Q200 qualification for automotive-grade reliability.
• Compliance & Packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.

Typical Applications

• Automotive Power Electronics: Energy storage and smoothing on medium-voltage DC rails in electronic control units and power modules where AEC-Q200 qualification is required.
• DC–DC Converters and Power Supplies: Input/output filtering and ripple attenuation in switch-mode power supplies, leveraging high ripple current capability across frequency.
• Industrial Ballasts and Drivers: AC ripple handling and bulk capacitance in lighting ballasts and LED drivers that demand long-life performance at elevated temperatures.

Unique Advantages

• Frequency-scaled Ripple Capability: Ripple current rating scales with frequency (coefficient 2.0 at 100 kHz), enabling higher AC ripple handling in high-frequency switching applications—demonstrated by 1.89 A at 100 kHz versus 945 mA at 120 Hz.
• Compact, Serviceable Form Factor: φ16 × 20 mm radial can with standardized 7.5 mm lead spacing provides a balance of capacitance and footprint for space-constrained boards.
• Proven Endurance at Elevated Temperature: 10,000-hour life at 105°C provides predictable aging and long-term performance for designs exposed to sustained heat.
• Automotive-Grade Qualification: AEC-Q200 rating supports use in automotive systems and other environments requiring component-level qualification and traceability.
• Measurable Leakage Behavior: Leakage current consistent with the 0.04CV+100 μA specification (1060 μA for this part), allowing designers to budget standby currents accurately.
