UCS2E820MND9

The UCS2E820MND9 is a radial-lead aluminum electrolytic capacitor from Nichicon’s UCS series, offering 82 µF capacitance at a 250 V rating. It combines a miniature φ10 × 40 mm can and 5 mm lead spacing with design attributes targeted at high ripple current handling and long operational life.

Designed for general-purpose power applications, the UCS2E820MND9 is suited to power supply and ballast use cases where sustained ripple endurance and extended life at elevated temperature are required.

Key Features

• Capacitance and Voltage: 82 µF nominal capacitance with a 250 V rated voltage for medium-voltage DC filtering and energy storage.
• Loss Angle (tan δ): tan δ (DF) max 0.20 measured at 20°C, 120 Hz, providing predictable AC loss characteristics for design validation.
• Ripple Current Capability: Low-frequency ripple current 610 mA at 120 Hz and high-frequency ripple current 1.22 A at 100 kHz, supporting demanding ripple environments.
• Endurance: Rated for 10,000 hours at 105°C (endurance test condition), aligning with long-life requirements in continuous-duty applications.
• Operating Range: Specified for −40°C to +105°C, enabling use across a wide ambient temperature span.
• Leakage Current: Measured leakage current of 920 µA after one minute at 20°C and rated voltage.
• Form Factor and Mounting: Radial lead (can) package, size φ10 × 40 mm with 5 mm lead spacing (±0.5 mm), for through-hole mounting and straightforward PCB placement.
• Compliance and Packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing.
• Lifecycle Status: End Of Life.

Typical Applications

• Power Supplies: DC filtering and smoothing where 250 V rating and high ripple tolerance are needed for stable output.
• Ballasts and Lighting Electronics: Filtering and energy buffering in ballast designs that require sustained ripple endurance at elevated temperatures.
• General-Purpose Industrial Electronics: Decoupling and bulk storage in industrial equipment that benefits from the UCS series’ long-life characteristics.

Unique Advantages

• High ripple endurance: Specified ripple currents of 610 mA (120 Hz) and 1.22 A (100 kHz) support designs with significant AC stress across the capacitor.
• Extended life at high temperature: 10,000-hour rated endurance at 105°C provides predictable longevity for continuous-duty applications.
• Compact radial can: φ10 × 40 mm can and 5 mm lead spacing enable compact, through-hole implementations without sacrificing ripple performance.
• Wide temperature operation: −40°C to +105°C rating accommodates a broad range of environmental conditions.
• Measured leakage specification: 920 µA leakage current figure allows designers to budget for standby and quiescent currents in system power budgets.
• RoHS compliant packaging options: Bulk and bag packing choices simplify procurement and board assembly workflows while meeting RoHS requirements.
