UCY2V820MHD

The UCY2V820MHD is a high-reliability miniature aluminum electrolytic capacitor in a radial lead can, optimized for demanding power applications. It provides 82 µF capacitance at a rated voltage of 350 V with a compact φ16 × 30.5 mm can and 7.5 mm lead spacing.

Designed for long-term operation and high ripple environments, this UCY series part is suited for power supply and ballast applications and is AEC‑Q200 qualified for use in automotive electronics where that qualification is required.

Key Features

• Capacitance & Voltage: 82 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 740 mA at 120 Hz and high‑frequency ripple current 1.48 A at 100 kHz (frequency coefficients apply).
• Long endurance: Rated life/endurance of 12,000 hours at 105 °C under the specified test conditions.
• Loss factor (tan δ): tan δ = 0.24 (measured at 20 °C, 120 Hz) for the 350 V rating, enabling predictable dissipation and thermal behavior.
• Leakage current: Measured leakage current 1,248 µA (per part data) after one minute’s application of rated voltage at 20 °C.
• Temperature range: Operates from −40 °C to +105 °C for broad environmental tolerance.
• Package & mounting: Radial lead can (φ16 × 30.5 mm), lead spacing 7.5 mm with 0.5 mm tolerance; available in bulk (no terminal forming) or bag packing.
• Standards & compliance: AEC‑Q200 qualified (series note) and RoHS compliant.

Typical Applications

• Power supplies: Bulk and smoothing capacitor for high‑voltage DC rails where high ripple current and long life at elevated temperature are required.
• Ballasts and lighting drivers: Energy storage and ripple suppression in ballast circuits, leveraging the series’ explicit suitability for ballast applications.
• Automotive electronic systems: Use in automotive power electronics where AEC‑Q200 qualification is required for high‑reliability designs.

Unique Advantages

• High ripple handling: Specified ripple currents at both low and high frequency (740 mA at 120 Hz, 1.48 A at 100 kHz) reduce heating in demanding AC‑coupled and switching environments.
• Extended high‑temperature life: 12,000-hour endurance at 105 °C supports designs that must maintain capacitance and leakage performance over long service intervals.
• Clear electrical characterization: Measured tan δ and leakage current values at standard conditions (20 °C, 120 Hz) provide predictable behavior for thermal and loss budgeting.
• Automotive‑grade option: AEC‑Q200 qualification provides traceable suitability for automotive and other high‑reliability programs.
• Compact radial form factor: φ16 × 30.5 mm can with 7.5 mm lead spacing offers a space‑efficient solution for through‑hole assemblies and prototyping.
• RoHS compliant packaging: Available in bulk or bag packing to support manufacturing and inventory needs while meeting RoHS requirements.

Why Choose UCY2V820MHD?

The UCY2V820MHD combines high ripple current capability, long operational life at elevated temperature, and clear electrical data to support reliable power‑stage designs.
