Key Features

• Capacitance & Voltage: 82 µF nominal capacitance with a 200 V rated voltage and tolerance of -20% to +20% for reliable energy storage and filtering in higher-voltage circuits.
• High Ripple-Current Performance: Low-frequency ripple current of 690 mA at 120 Hz and high-frequency ripple current of 1.38 A at 100 kHz to handle sustained AC ripple in switching and power-conversion applications.
• Long Life at Elevated Temperature: Rated for 10,000 hours at +105°C, providing long-term endurance under continuous thermal and electrical stress.
• Low Dissipation Factor: tanδ (DF) max 0.20 measured at 20°C, 120 Hz, indicating low equivalent series losses for improved efficiency.
• Compact Radial Can Package: φ16 × 20 mm can with radial leads and 7.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB layouts requiring a small footprint.
• Leakage Current: Specified leakage current 756 µA, supporting predictable bias behavior after voltage application.
• Regulatory & Quality: AEC-Q200 qualified and RoHS compliant, targeting applications that require automotive-grade reliability and lead-free material compliance.
• Packaging Options: Available in bulk (no terminal forming) and bag packing to support different assembly and handling preferences.

Typical Applications

• Power Supplies: Bulk and output filtering in switch-mode and linear power supplies where 200 V ratings and high ripple capacity are required.
• Ballasts and Lighting Drivers: Smoothing and ripple control in ballast or driver circuits as cited in the UCY series datasheet.
• Automotive Power Electronics: Use in automotive power systems and auxiliary electronics that require AEC-Q200 qualification and extended high-temperature life.
• Industrial Electronics: High-reliability filtering and energy storage in industrial control and power conversion equipment operating across -40°C to +105°C.

Unique Advantages

• High ripple tolerance: Dual-spec ripple ratings (690 mA at 120 Hz and 1.38 A at 100 kHz) enable reliable performance across low and high switching frequencies.
• Extended operational life at 105°C: 10,000-hour endurance rating reduces maintenance and replacement frequency in continuous-duty applications.
• AEC-Q200 qualification: Provides an established qualification level for designs that require automotive-grade reliability.
• Compact radial footprint: φ16 × 20 mm can with standard lead spacing supports space-constrained board designs while retaining high-voltage capability.
• Low loss characteristics: tanδ ≤ 0.20 at 20°C, 120 Hz contributes to efficient operation and predictable thermal behavior.
• RoHS compliant materials: Meets current lead-free and restricted-substance requirements for regulated markets.
