UCY2E820MHD9

The UCY2E820MHD9 is a radial lead aluminum electrolytic capacitor engineered for high ripple current and long-life performance in compact power assemblies. It delivers 82 µF at a 250 V rating in a φ12.5 × 25 mm can with 5 mm lead spacing, optimized for through-hole power filtering and ballast or power-supply applications.

Designed to operate from −40°C to +105°C with a rated endurance of 12,000 hours at 105°C, this part provides a robust polarized capacitance option for applications requiring sustained high-frequency and low-frequency ripple handling and tight mechanical form factor control.

Key Features

• Capacitance & Voltage: 82 µF capacitance at a 250 V rated voltage, with capacitance tolerance of −20% to +20%.
• High ripple-current capability: Low-frequency ripple current of 615 mA at 120 Hz and high-frequency ripple current of 1.23 A at 100 kHz, enabling effective smoothing across a wide frequency range.
• Long endurance: Rated for 12,000 hours at +105°C under DC bias plus rated ripple conditions, supporting prolonged reliability in demanding thermal environments.
• Temperature range: Specified operating range from −40°C to +105°C for use across harsh ambient conditions.
• Low loss (tan δ): tanδ of 0.20 measured at 20°C and 120 Hz, supporting efficient energy handling with predictable dissipation.
• Compact radial can: φ12.5 × 25 mm package with 5.0 mm lead spacing (±0.5 mm), suitable for dense through-hole layouts; available in bulk/no terminal forming or bag packing.
• Leakage current: Specified leakage current of 920 µA, enabling predictable bias behavior after voltage application.
• Standards & compliance: AEC-Q200 rated and RoHS compliant for regulated production environments and automotive-grade system design.

Typical Applications

• Power supplies: Bulk smoothing and decoupling in switch-mode and linear power supplies where high ripple handling and long life are required.
• Ballasts and lighting drives: Filtering and energy storage in ballast circuits, leveraging the UCY series suitability for power-supply and ballast applications.
• Automotive electronics: Power filtering and energy buffering in vehicle systems where AEC-Q200 qualification and wide temperature capability are required.

Unique Advantages

• High ripple endurance: Rated ripple currents at both low and high frequencies reduce thermal stress on assemblies and improve ripple attenuation without oversizing the capacitor.
• Long operational life at elevated temperature: 12,000-hour endurance at 105°C supports extended maintenance intervals and improved system uptime.
• Compact radial form factor: φ12.5 × 25 mm can and 5 mm lead spacing fit tight through-hole layouts while retaining robust performance.
• Automotive-capable design: AEC-Q200 rating and a −40°C to +105°C operating range allow use in temperature- and vibration-challenged vehicle electronics.
• RoHS compliant production: Built to current environmental directives for straightforward regulatory alignment.
