UCS2G820MHD

The UCS2G820MHD is a miniature aluminum electrolytic capacitor in a radial‑lead can package designed for applications requiring high ripple current and extended life at elevated temperatures. It offers 82 μF capacitance at a 400 V rating and is polarized for DC applications.

Engineered for use in power supply and ballast applications, the part combines high ripple capability with a rated lifetime of 10,000 hours at +105°C and RoHS compliance for environmentally conscious designs.

Key Features

• Electrical Performance — 82 μF capacitance with a 400 V rated voltage and ±20% tolerance for bulk energy storage and filtering in high‑voltage circuits.
• High Ripple Current — Rated ripple current of 762.5 mA at 120 Hz and 1.525 A at 100 kHz, supporting demanding AC superimposed or switching environments.
• Long Endurance at High Temperature — Load life of 10,000 hours at +105°C (with specific shorter life variants noted in series documentation) for sustained operation in hot environments.
• Temperature Range — Operating from −40°C to +105°C to accommodate a wide range of thermal conditions.
• Package and Mounting — Radial lead, can package with 7.5 mm lead spacing and compact dimensions (L: 2.5 × D: 1.8 cm), simplifying through‑hole assembly.
• Polarized Design — Intended for DC applications where polarized electrolytic capacitance is required.
• Compliance — RoHS compliant per the provided directive references.

Typical Applications

• Power Supplies — Bulk filtering and ripple smoothing in high‑voltage DC power rails, leveraging the 400 V rating and high ripple current capability.
• Ballasts — Energy storage and ripple handling in ballast circuits where elevated operating temperature and long life are important.
• General Purpose Electronics — Through‑hole radial mounting for a variety of industrial and commercial designs requiring polarized electrolytic capacitance.

Unique Advantages

• Extended High‑Temperature Life: 10,000 hours at +105°C provides predictable endurance for designs exposed to sustained heat.
• High Voltage Handling: 400 V rating enables use in higher‑voltage DC systems without needing multiple series capacitors.
• Robust Ripple Performance: Specified ripple currents at both 120 Hz and 100 kHz support both line‑frequency and high‑frequency switching applications.
• Compact Radial Can: Small footprint (L: 2.5 × D: 1.8 cm) with 7.5 mm lead spacing helps conserve PCB space while retaining through‑hole reliability.
• Regulatory Compliance: RoHS compliance supports designs that must meet environmental substance requirements.
• Polarized for DC Use: Simplifies selection for DC energy storage and filtering applications where polarity is known and controlled.
