UCS2E820MHD

The UCS2E820MHD is an aluminum electrolytic capacitor in Nichicon’s UCS series, designed for miniature, radial-lead installations where high ripple current and long operational life are required. It delivers 82 µF at a 250 V rating and is built for power supply and ballast applications.

Engineered for reliability in elevated-temperature environments, this polarized radial-can capacitor withstands extended load life at +105°C and is RoHS compliant.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a 250 V rated voltage suitable for medium-voltage power circuits.
• High ripple current capability — Rated ripple current of 690 mA at 120 Hz and 1.38 A at 100 kHz, supporting applications with significant AC ripple on DC rails.
• Long operational life at elevated temperature — Designed to withstand 10000 hours at +105°C under rated conditions (endurance per series specification).
• Operating temperature range — Functional from −40°C to +105°C to cover a wide range of industrial ambient conditions.
• Package & mounting — Radial lead, can-style package with 7.5 mm lead spacing for through-hole mounting and compact board placement; case diameter approximately 1.6 cm.
• Electrical stability — Capacitance tolerance ±20% and a tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C for the 250 V rating.
• Leakage current specification — After 1 minute at 20°C, leakage current is specified as not more than 0.04CV + 100 µA (per series datasheet formula).
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized — Intended for DC applications requiring correct polarity orientation.

Typical Applications

• Power supplies — Used in power conversion and filtering circuits where high ripple current capability improves reliability under heavy load conditions.
• Ballast circuits — Suited for ballast applications that demand stable capacitance and long life at elevated operating temperatures.
• General-purpose power electronics — Applicable where a compact, high-voltage electrolytic is required for bulk capacitance and ripple handling.

Unique Advantages

• Extended life at high temperature — 10000-hour endurance at +105°C reduces frequency of replacement in high-stress environments.
• High AC ripple handling — Specified ripple currents at 120 Hz and 100 kHz support both low- and high-frequency ripple conditions encountered in modern power designs.
• Compact radial-can form factor — Small diameter (≈1.6 cm) and 7.5 mm lead spacing provide a space-efficient solution for through-hole boards.
• Predictable electrical behavior — Clear specifications for tan δ, leakage current, and tolerance allow straightforward integration into design margin calculations.
• Regulatory compliance — RoHS conformity simplifies selection for products targeting regulated markets.
