UCY2V820MHD3

The UCY2V820MHD3 is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can designed for high-voltage applications. Built for demanding power-handling tasks, it combines 82 µF capacitance with a 350 V rating, a wide operating temperature range (−40 °C to 105 °C) and a long endurance rating to support continuous operation in elevated-temperature environments.

Typical use cases include power supply filtering and ballast circuits where high ripple current capability, long life and AEC-Q200 qualification are required. The part is available in bulk or bag packaging and is in mass production from Nichicon.

Key Features

• Capacitance and Voltage: 82 µF nominal capacitance with a 350 V rated voltage and ±20% tolerance for high-voltage smoothing and energy buffering.
• High ripple current capability: Rated for 765 mA at 120 Hz (low frequency) and 1.53 A at 100 kHz (high frequency), supporting heavy ripple conditions in power circuits.
• Long endurance at elevated temperature: Rated life of 12,000 hours at 105 °C under specified DC bias plus ripple current, suitable for sustained high-temperature operation.
• Electrical loss and leakage: Maximum tan δ of 0.24 at 20 °C, 120 Hz; specified leakage current of 1,248 µA for the part as produced.
• Package and mounting: Radial lead can (φ18 × 25L) with 7.5 mm lead spacing for through-hole mounting and straightforward assembly.
• Quality and environmental compliance: AEC-Q200 qualified and RoHS compliant, supporting use in regulated designs and environments.
• Packaging options: Available in Bulk (no terminal forming) or Bag Packing to suit production handling preferences.

Typical Applications

• Power supplies: Bulk energy storage and smoothing in high-voltage DC power supply stages where 350 V rating and high ripple tolerance are required.
• Ballast circuits: Filtering and ripple management in lighting or ballast applications noted in the UCY series documentation.
• Industrial electronics: Energy buffering and decoupling in industrial power modules operating across −40 °C to 105 °C.
• Automotive electronics: Use in automotive systems where AEC-Q200 qualification and long life at elevated temperature are factors in component selection.

Unique Advantages

• High-voltage capability: 350 V rating enables direct use in high-voltage rails without series stacking or additional components.
• Designed for sustained ripple: Specified ripple currents at both low and high frequencies reduce thermal stress and improve reliability under continuous load.
• Extended life at 105 °C: 12,000-hour endurance rating at 105 °C provides predictable long-term performance in hot operating environments.
• AEC-Q200 qualification: Recognized quality standard supports deployment in demanding applications that require component-level qualification.
• Compact radial form factor: φ18 × 25L can with 7.5 mm lead spacing provides a compact through-hole solution that is easy to place and solder in power assemblies.
• RoHS compliant: Meets environmental directive requirements for regulated assemblies.
