UCS2V820MHD

The UCS2V820MHD is an aluminum electrolytic capacitor from Nichicon's UCS series, designed as a miniature, radial-lead can for high-voltage applications. It delivers 82 µF at a 350 V rating with polarization and a compact footprint suited to space-constrained through-hole designs.

Engineered for power-supply and ballast applications, the part emphasizes high ripple-current capability and long operational life, rated for extended load life at elevated temperature and compliant with RoHS requirements.

Key Features

• Electrical Performance — 82 µF capacitance at a 350 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• High Ripple Current — Rated ripple current of 1.53 A at 100 kHz and 765 mA at 120 Hz, with frequency coefficients defined for ripple scaling (120 Hz = 0.50, 100 kHz+ = 1.00).
• Long Life / High Temperature Endurance — Specified load life of 10000 hours at +105°C (series endurance defined as 8000–10000 hours depending on size).
• Wide Operating Range — Operating temperature range from −40°C to +105°C for broad environmental tolerance.
• Radial Through-Hole Package — Radial lead, can-style package with 7.5 mm lead spacing and compact physical size (L: 2.5 × D: 1.8 cm).
• Leakage Current Specification — Series leakage current defined as not more than 0.04CV + 100 µA after one minute at 20°C, for predictable bias behavior.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Smoothing and filtering in high-voltage power supplies where compact, high-voltage capacitors with strong ripple handling are required.
• Ballasts — Energy-storage and ripple-management duties in ballast circuits, leveraging the part’s high ripple-current capability and long-life rating.
• General Purpose High-Voltage Circuits — Through-hole designs that need polarized aluminum electrolytic capacitors with verified endurance at elevated temperature.

Unique Advantages

• High ripple-current capability: Supports up to 1.53 A at 100 kHz (1.53 A HF rating) and 765 mA at 120 Hz, reducing thermal stress in AC-biased applications.
• Extended high-temperature life: Rated for 10000 hours at +105°C, enabling longer maintenance intervals and predictable lifetime in hot operating environments.
• Compact radial can package: Small L × D footprint (2.5 × 1.8 cm) with 7.5 mm lead spacing for space-efficient through-hole layouts.
• Predictable leakage behavior: Leakage current bound by the datasheet formula (0.04CV + 100 µA after 1 minute at 20°C) for reliable bias planning.
• RoHS compliance: Meets current RoHS directives, supporting environmental and regulatory requirements.
