UCY2V101MHD

The UCY2V101MHD is a radial-lead aluminum electrolytic capacitor offering 100 µF capacitance at a 350 V rating in a compact φ16 × 30.5 mm can. Designed for high-ripple, long-life applications, it targets power supply and ballast circuits where sustained performance at elevated temperature is required.

This polarized capacitor delivers high ripple-current capability and a long endurance rating at elevated temperature, making it suitable for demanding embedded and automotive-related electronics that require robust smoothing and energy-storage components.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 350 V and capacitance tolerance of −20% to +20%.
• High ripple-current capability — Low frequency ripple current of 825 mA at 120 Hz and high frequency ripple current up to 1.65 A at 100 kHz, supporting demanding supply-decoupling and filtering loads.
• Long life at elevated temperature — Rated for 12,000 hours of endurance at 105°C under DC bias plus rated ripple current, supporting extended operational lifetimes in harsh thermal environments.
• Wide operating temperature — Specified for −40°C to +105°C operation to cover cold-start and high-ambient scenarios.
• Electrical characteristics — Dissipation factor (tan δ) of 0.24 measured at 20°C, 120 Hz; specified leakage current 1,500 µA.
• Radial can package — φ16 × 30.5 mm case with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies; available in bulk or bag packing.
• AEC-Q200 qualified — Series-level AEC-Q200 qualification indicated in the product data, supporting designs targeting automotive application segments.
• RoHS compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Power supplies — Bulk smoothing and output filtering in AC/DC and DC/DC converters where high ripple endurance and long life are required.
• Ballasts and lighting drivers — Energy storage and ripple suppression in ballast circuits as noted in the product series documentation.
• Automotive electronics — Support for in-vehicle power systems and electronic modules where AEC-Q200 qualification and an extended temperature range are relevant.
• Industrial power systems — Filtering and decoupling in industrial converters and motor drive front-ends that operate at elevated temperatures and high ripple currents.

Unique Advantages

• High ripple-current handling: Specified ripple currents of 825 mA (120 Hz) and 1.65 A (100 kHz) enable reliable filtering under high AC stress.
• Extended high-temperature life: 12,000-hour endurance at 105°C provides predictable aging behavior for long-term deployments.
• Automotive-capable qualification: AEC-Q200 rating at the series level supports use in automotive-related designs that require component qualification.
• Compact radial form factor: φ16 × 30.5 mm can with 7.5 mm lead spacing simplifies layout for through-hole assemblies while maintaining capacitance density.
• Verified electrical behavior: Measured tan δ of 0.24 and specified leakage current (1,500 µA) allow engineers to model losses and leakage in power budgets.
• Supply and packaging flexibility: Available in bulk (no terminal forming) or bag packing to fit manufacturing and procurement preferences.
