UCY2G820MHD3

The UCY2G820MHD3 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UCY series. It is a radial‑lead, polarized can designed for high‑voltage power applications where high ripple current and long operational life at elevated temperatures are required.

Typical use cases include power supplies, lighting ballast circuits and automotive electronics that demand high ripple handling, long endurance at 105°C, and AEC‑Q200 qualification.

Key Features

• Electrical — Capacitance & Tolerance: 82 µF nominal with a capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Rated Voltage: 400 V DC rated for high‑voltage power rails.
• Ripple Current Performance: Low‑frequency ripple current 765 mA at 120 Hz and high‑frequency ripple current 1.53 A at 100 kHz, supporting demanding AC ripple environments.
• Loss Tangent (tan δ): tan δ = 0.24 (maximum) measured at 20°C, 120 Hz.
• Leakage Current: Specified leakage current of 1412 µA.
• High Temperature Endurance: Rated life of 12,000 hours at 105°C under specified test conditions.
• Temperature Range: Operates from −40°C to +105°C.
• Mechanical — Compact Radial Can: Diameter φ18 mm × length 25 mm with 7.5 mm lead spacing (lead spacing tolerance ±0.5 mm); radial lead mounting.
• Packaging Options: Available in Bulk (no terminal forming) or Bag packing.
• Quality & Compliance: AEC‑Q200 qualified and RoHS compliant.
• Frequency Coefficient: Frequency coefficient of rated ripple current up to 2.00 at 100 kHz or more, enabling higher allowable ripple at higher frequencies.

Typical Applications

• Power Supplies: Energy storage and smoothing on high‑voltage DC rails where 400 V rating and high ripple capability are required.
• Lighting Ballasts: Bulk and filter capacitance for ballast circuits that require high ripple handling and long life at elevated temperatures.
• Automotive Electronics: High‑voltage power modules and systems benefiting from AEC‑Q200 qualification and extended endurance at 105°C.

Unique Advantages

• High ripple current capability: Specified ripple ratings at both low (765 mA at 120 Hz) and high frequencies (1.53 A at 100 kHz) support demanding power environments.
• Long operational life at elevated temperature: 12,000 hours endurance at 105°C provides predictable service life in hot operating conditions.
• AEC‑Q200 qualification: Supports automotive and high‑reliability system design requirements where component qualification is required.
• Compact radial package: φ18 × 25 mm can with 7.5 mm lead spacing offers a space‑efficient solution for through‑hole assembly and robust mechanical mounting.
• Wide operating temperature range: −40°C to +105°C suitability for applications exposed to broad thermal conditions.
• RoHS compliant: Meets environmental substance requirements for modern electronic assemblies.
