UCY2H680MHD

The UCY2H680MHD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon's UCY series designed for high ripple current and long-term reliability. It delivers 68 µF at a 500 V rating in a compact φ18 × 40 mm can with 7.5 mm lead spacing.

Targeted for power supply and ballast applications and qualified to AEC‑Q200, this capacitor is suited to designs requiring sustained performance at elevated temperatures and extended lifetimes.

Key Features

• Capacitance & Voltage: 68 µF rated at 500 V for high-voltage bulk or filtering applications.
• High ripple current capability: Low-frequency ripple current 525 mA at 120 Hz and high-frequency ripple current 1.05 A at 100 kHz to support demanding power circuits.
• Long operational life: Endurance rated for 10000 hours at +105°C under specified conditions, supporting long-term reliability in hot environments.
• Temperature range: –40°C to +105°C operating range suitable for elevated-temperature applications.
• Electrical characteristics: Capacitance tolerance –20% to +20% and tan δ (DF) 0.24 measured at 20°C, 120 Hz for predictable AC behavior.
• Leakage current: Specified leakage current 1460 µA (per product data) to assist in power budget and discharge considerations.
• Package and mounting: Radial lead can, size φ18 × 40 mm with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing for through-hole assembly.
• Compliance and qualification: AEC‑Q200 qualified and RoHS compliant, reflecting suitability for regulated and high-reliability applications.

Typical Applications

• Power supplies and ballasts: Used for smoothing, bulk storage, and ripple handling in power conversion and lighting ballast circuits.
• Automotive electronic systems: AEC‑Q200 qualification and high-temperature endurance make it suitable for automotive power circuits and control units requiring long life.
• High-temperature environments: Designed for applications that operate up to +105°C for extended periods, where reliability over thousands of hours is required.

Unique Advantages

• High-voltage capability: 500 V rating enables use in higher-voltage power and ballast applications without series stacking.
• Designed for ripple-heavy circuits: High ripple current ratings at both low and high frequencies reduce heating and extend service life in demanding circuits.
• Proven long-life performance: 10000-hour endurance at 105°C provides predictable lifetime behavior for maintenance planning and long-term deployments.
• Automotive-grade qualification: AEC‑Q200 qualification supports deployment in regulated automotive and similarly demanding applications.
• Compact, through-hole form factor: φ18 × 40 mm radial can with 7.5 mm lead spacing is easy to integrate in through-hole layouts while minimizing board footprint.
• Regulatory compliance: RoHS compliant to meet environmental requirements in end products.
