UCY2E101MHD

The UCY2E101MHD is a miniature, radial-lead aluminum electrolytic capacitor designed for high-reliability power applications. It delivers 100 µF at 250 V in a compact φ16 × 20 mm can with 7.5 mm lead spacing, optimized for sustained ripple handling and long life in demanding environments.

Engineered for applications requiring robust performance over extended operating periods, this AEC-Q200-qualified, RoHS-compliant part supports automotive and industrial power-supply use cases with a rated temperature range of -40°C to +105°C and a specified 10,000-hour life at 105°C.

Key Features

• Capacitance and Voltage: 100 µF rated capacitance at 250 V to support bulk energy storage and decoupling in higher-voltage power rails.
• High Reliability Construction: Miniature aluminum electrolytic design with radial-lead package and polarized can for compact, through-hole implementations.
• Long Endurance: Rated for 10,000 hours at +105°C under specified load conditions, providing predictable life for high-temperature applications.
• Ripple Current Performance: Low-frequency ripple current 715 mA (120 Hz) and high-frequency ripple current 1.43 A (100 kHz) for effective handling of both mains-frequency and switching ripple.
• Loss and Leakage: Tan δ (DF) ≤ 0.20 measured at 20°C, 120 Hz; leakage current ≤ 1,100 µA after 1 minute at 20°C (per datasheet formula 0.04CV+100).
• Mechanical and Packaging: Size φ16 × 20 mm with 7.5 mm lead spacing (±0.5 mm); available in bulk or bag packing for production and prototyping.
• Standards and Compliance: AEC-Q200 qualified and RoHS compliant, supporting regulated and reliability-conscious designs.

Typical Applications

• Power Supplies: Bulk smoothing and ripple suppression on higher-voltage DC rails in switching and linear power supplies.
• Automotive Electronics: Power conditioning and energy storage in control modules and auxiliary power circuits where AEC-Q200 qualification is required.
• Industrial Control: Energy buffering and high-ripple filtering in motor drives, ballasts, and industrial power converters operating across -40°C to +105°C.

Unique Advantages

• High-Temperature Endurance: 10,000-hour rated lifetime at 105°C gives designers predictable long-term performance in hot operating environments.
• Dual-Frequency Ripple Handling: Specified ripple current at both 120 Hz and 100 kHz supports mixed mains and high-frequency switching applications without overspecifying components.
• Vehicle-Grade Qualification: AEC-Q200 qualification enables use where automotive-grade components are mandated.
• Compact Through-Hole Form Factor: φ16 × 20 mm radial-lead can with 7.5 mm lead spacing balances board-space economy with robust mechanical mounting.
• Verifiable Electrical Limits: Clear datasheet-based limits for tan δ and leakage current support deterministic circuit design and margining.
