UCYW6680MHD3

The UCYW6680MHD3 is a radial‑lead aluminum electrolytic capacitor designed for high‑ripple, long‑life applications. It delivers 68 μF capacitance at a 420 V rating in a compact φ18 × 25 mm can with 7.5 mm lead spacing.

Targeted at power electronics and automotive use, this AEC‑Q200 qualified, RoHS‑compliant capacitor offers high ripple current capability and extended endurance for demanding operating environments up to 105°C.

Key Features

• Capacitance and Voltage: 68 μF nominal capacitance with a 420 V rated voltage and ±20% tolerance, suitable for high‑voltage smoothing and energy storage.
• High ripple current capability: Low‑frequency ripple current of 615 mA at 120 Hz and high‑frequency ripple current of 1.23 A at 100 kHz, supporting heavy AC superposition loads.
• Long endurance at elevated temperature: Rated for 12,000 hours life at 105°C under specified DC bias plus rated ripple current, providing extended service life in hot environments.
• Temperature range: Wide operating range from −40°C to +105°C for reliable operation across typical industrial and automotive temperature profiles.
• Electrical loss characteristics: tan δ (DF) of 0.24 measured at 20°C, 120 Hz, for predictable dissipation behavior.
• Leakage current: Specified leakage current of 1,242.4 μA, measured per product test conditions.
• Package and mounting: Radial, polarized can package (φ18 × 25L) with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing for production handling.
• Standards and compliance: AEC‑Q200 qualified and RoHS compliant, aligning with automotive and environmental requirements.

Typical Applications

• Power supplies: DC smoothing and bulk energy storage where high voltage and reliable ripple handling are required.
• Ballasts and lighting power equipment: Filtering and ripple suppression in ballast circuits and related power conversion stages.
• Automotive electronic modules: High‑voltage filtering and decoupling in electronic control units and power subsystems that require AEC‑Q200 qualified components.
• Industrial converters and inverters: Energy buffering and ripple management in medium‑to‑high voltage converter stages.

Unique Advantages

• Extended high‑temperature life: 12,000 hours at 105°C supports designs that must sustain long service life under thermal stress.
• Robust ripple handling: Specified low‑ and high‑frequency ripple current ratings reduce thermal rise and improve reliability in AC‑loaded circuits.
• Automotive readiness: AEC‑Q200 qualification enables use in automotive applications that require component‑level reliability validation.
• Compact radial can format: φ18 × 25 mm can with 7.5 mm lead spacing offers a space‑efficient solution for through‑hole assemblies and retrofit designs.
• Regulatory compliance: RoHS compliance supports environmental regulatory requirements and end‑product compliance efforts.
