UCY2E820MHD

The UCY2E820MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series, specified at 82 µF and 250 V. It delivers high ripple-current capability and extended load life in a compact radial can package designed for demanding power applications.

Designed for automotive and power-supply environments, the UCY2E820MHD combines long endurance at elevated temperature with AEC-Q200 qualification and RoHS compliance to support robust, high-reliability designs.

Key Features

• Electrical Performance — 82 µF nominal capacitance with tolerance of -20% to +20% at 120 Hz/20°C; tanδ (DF) specified at 0.20 for 250 V at 20°C/120 Hz.
• Rated Voltage — 250 V DC rating suitable for higher-voltage power filtering and energy-storage roles.
• Ripple Current Capability — Low-frequency ripple current 715 mA at 120 Hz and high-frequency ripple current 1.43 A at 100 kHz, enabling effective smoothing across a range of switching frequencies.
• High Temperature Endurance — Load-life endurance of 12,000 hours at 105°C when subjected to rated DC bias plus rated ripple current, with capacitance and leakage current meeting endurance criteria after test.
• Temperature Range — Operates from −40°C to +105°C for broad environmental tolerance.
• Package & Mechanical — Radial can, size φ12.5 × 30.5 mm (D × L), lead spacing 5.0 mm (±0.5 mm); lead diameter for this length is 0.8 mm; available in bulk or bag packing (no terminal forming).
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant, supporting regulated and automotive-focused designs.

Typical Applications

• Automotive Electronics — Bulk filtering and decoupling in automotive power subsystems where high ripple handling and long life at 105°C are required.
• Power Supplies — Output smoothing and energy storage for linear and switching power supplies benefiting from high ripple-current capability across low and high frequencies.
• Ballast Applications — Designed for ballast and related lighting power circuits where sustained ripple performance and endurance improve system reliability.

Unique Advantages

• High ripple-current handling: Specified ripple currents of 715 mA (120 Hz) and 1.43 A (100 kHz) let designers manage both low-frequency and high-frequency ripple without oversizing the capacitor.
• Extended high-temperature life: 12,000 hours endurance at 105°C under rated conditions provides predictable lifespan for thermal-stressed designs.
• AEC-Q200 qualification: Explicit AEC-Q200 rating supports selection for automotive and similarly demanding applications requiring qualified components.
• Compact radial can format: φ12.5 × 30.5 mm package with 5 mm lead spacing fits space-constrained layouts while maintaining through-hole robustness.
• Regulatory compliance: RoHS-compliant construction simplifies integration into regulated product lines.
