UCY2E680MHD

The UCY2E680MHD is a radial‑lead, miniature aluminum electrolytic capacitor in Nichicon’s UCY series designed for high reliability power circuits. It provides 68 µF capacitance at a 250 V rating in a compact φ12.5 × 25 mm can with 5.0 mm lead spacing.

Engineered for power supply and ballast applications and specified for automotive use (AEC‑Q200), this part combines high ripple current capability, long endurance at elevated temperature, and RoHS compliance for demanding electronic systems.

Key Features

• Capacitance & Voltage: 68 µF rated at 250 V for energy storage and smoothing in medium‑voltage circuits.
• High ripple current handling: 615 mA at 120 Hz (low frequency) and 1.23 A at 100 kHz (high frequency), enabling effective filtering under AC and switching conditions.
• Long endurance: Rated life of 12,000 hours at 105 °C under DC bias plus rated ripple current, delivering sustained performance in high‑temperature environments.
• Low dissipation factor: tanδ 0.20 measured at 20 °C, 120 Hz (at 250 V), for efficient operation with reduced losses.
• Leakage current: Specified leakage current of 780 µA to support predictable bias behavior.
• Robust environmental and quality credentials: AEC‑Q200 qualification and RoHS compliance for use in regulated and automotive applications.
• Mechanical package: Radial lead (can) package with φ12.5 mm diameter, 25 mm length, and 5.0 mm lead spacing (±0.5 mm), available in bulk or bag packing.

Typical Applications

• Power supplies: Filtering and smoothing in AC/DC and DC/DC power stages where high ripple current and long life at elevated temperatures are required.
• Ballasts and lighting drivers: Energy buffering and ripple suppression in ballast circuits for reliable lamp operation.
• Automotive electronics: Bulk filtering and decoupling in automotive systems where AEC‑Q200 qualification and extended endurance at 105 °C are important design considerations.

Unique Advantages

• Designed for high ripple environments: Defined ripple current ratings at both low and high frequencies (615 mA at 120 Hz; 1.23 A at 100 kHz) provide designers with clear performance margins for switching and line‑frequency applications.
• Proven long life at temperature: 12,000‑hour endurance at 105 °C supports long service intervals and predictable ageing in thermal stress conditions.
• Automotive‑grade option: AEC‑Q200 qualification makes the part suitable for automotive and similarly demanding applications that require component qualification.
• Compact radial can format: φ12.5 × 25 mm package with 5.0 mm lead spacing offers a space‑efficient solution for through‑hole assemblies.
• Low loss and controlled leakage: Tanδ 0.20 and specified leakage current (780 µA) enable efficient energy handling and stable bias behavior over life.
• Regulatory compliance: RoHS compliant for use in products targeting regulated markets.
