UCS2D820MHD

The UCS2D820MHD is an aluminum electrolytic capacitor in a radial can package designed for compact, high-ripple current applications. It delivers 82 µF at 200 V in a miniature radial-lead form factor suited for power supply and ballast applications as well as other general-purpose circuits.

Key value propositions include high ripple-current capability across low and high frequencies, long life at elevated temperature, and RoHS compliance, making it suitable for designs that require durable capacitive filtering under sustained thermal and electrical stress.

Key Features

• Electrical Rating — 82 µF capacitance at 200 V rated voltage with ±20% tolerance, providing a clear specification for filter and energy-storage uses.
• High Ripple Current — Rated ripple current of 690 mA at 120 Hz and 1.38 A at 100 kHz, supporting heavy AC ripple and switching-frequency applications.
• Long Life at Elevated Temperature — Designed to meet a rated lifetime of 10000 hours at +105°C under specified loading conditions, enabling extended field life in hot environments.
• Wide Operating Temperature — Specified for –40°C to +105°C operation to cover a broad range of ambient conditions.
• Low-Frequency Leakage Specification — Leakage current defined by the series specification (≤ 0.04CV + 100 µA after 1 minute at 20°C), allowing predictable end-of-life and idle performance planning.
• Compact Radial Package — Radial lead, can-style package with 7.5 mm lead spacing and compact footprint (L: 2 cm × D: 1.6 cm), suitable for through-hole board layouts.
• RoHS Compliant — Meets the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• Power Supplies — Bulk filtering and ripple smoothing in AC/DC and DC/DC converters where sustained ripple currents and elevated temperatures are present.
• Ballasts — Energy storage and filtering in ballast circuits where high ripple tolerance and durability at +105°C are required.
• General-Purpose Electronic Equipment — Use in assemblies that demand compact radial electrolytic capacitors with defined lifetime and ripple specifications.

Unique Advantages

• Designed for High Ripple Environments: Explicit ripple ratings at both 120 Hz and 100 kHz let you size capacitors for mains-frequency and switching-frequency ripple without guesswork.
• Long-Term Thermal Endurance: 10000-hour rating at +105°C supports prolonged operation under thermal stress, reducing maintenance and replacement frequency.
• Predictable Leakage Behavior: Leakage current defined by the series formula (0.04CV + 100 µA) helps with power budgeting and initial-charge considerations.
• Compact Radial Form Factor: Small can and radial-lead footprint enable dense through-hole layouts and straightforward retrofit into existing board designs.
• Regulatory Compliance: RoHS conformity simplifies regulatory tracking and supports deployment in RoHS-restricted markets.
