UCY2C391MHD

The UCY2C391MHD is a miniature aluminum electrolytic capacitor in a radial‑lead can, designed for high ripple current and long operational life. It delivers 390 µF at 160 V in a compact φ16×40 mm package with 7.5 mm lead spacing, targeting power supply and automotive electronic applications that require durable, high‑performance bulk energy storage.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance with a 160 V rated voltage and a tolerance of ±20% at 20°C, 120 Hz.
• High Ripple Current — Handles 1.73 A low‑frequency ripple at 120 Hz and 3.46 A high‑frequency ripple at 100 kHz, supporting demanding power filtering and decoupling tasks.
• Long Endurance — Rated life of 12,000 hours at 105°C (with specified DC bias plus rated ripple current), engineered for extended field service in harsh conditions.
• Thermal Range — Operating temperature range from −40°C to +105°C for reliable performance across wide ambient conditions.
• Electrical Loss & Leakage — tanδ (DF) 0.2 max at 20°C, 120 Hz; specified leakage current consistent with the UCY series formula (after 1 minute at rated voltage).
• Automotive Qualification — AEC‑Q200 rated for use in automotive electronics where qualified passive components are required.
• Package & Mounting — Radial lead, polarized aluminum can; physical dimensions φ16×40L with 7.5 mm lead spacing for through‑hole assembly.
• Compliance — RoHS compliant to applicable directives.

Typical Applications

• Automotive electronic modules — Energy storage and smoothing in control units and power electronics where AEC‑Q200 qualification is required.
• Power supplies — Bulk capacitance and ripple mitigation in DC‑DC converters and linear supplies operating up to 160 V.
• Ballasts and lighting power circuits — Designed for the high ripple demands noted for ballast applications.

Unique Advantages

• High ripple handling capability: Specified ripple currents at 120 Hz and 100 kHz enable reliable filtering across a broad frequency range.
• Extended operational life: 12,000‑hour endurance at 105°C supports long service intervals and reduced maintenance in deployed systems.
• Automotive‑grade reliability: AEC‑Q200 rating provides proven suitability for automotive electronic designs.
• Compact radial package: φ16×40 mm can with 7.5 mm lead spacing maximizes capacitance in a small through‑hole footprint for power-dense boards.
• Wide temperature performance: −40°C to +105°C operation accommodates harsh ambient and under‑hood environments.
• Regulatory compliance: RoHS conformity simplifies integration into compliant product lines.
