Key Features

• Capacitance & Tolerance — 47 µF with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated for 450 V DC for applications requiring elevated DC bus or high-voltage filtering.
• High Ripple Current — Low-frequency ripple current 500 mA (120 Hz) and high-frequency ripple current 1.0 A (100 kHz), supporting both mains-frequency and high-frequency converter environments.
• Long Endurance at Elevated Temperature — Rated for 12,000 hours at 105°C under rated DC bias plus ripple conditions, enabling extended service life in thermal stress environments.
• Temperature Range — Operates from −40°C to +105°C to cover a wide range of environmental conditions.
• Loss Characteristics — Tangent of loss angle (tanδ) of 0.24 (measured at 20°C, 120 Hz), useful for assessing dissipation and AC performance.
• Leakage Current — Specified leakage current of 946 µA (measured after rated voltage application conditions), suitable for power circuitry where standby leakage must be managed.
• Automotive Grade — AEC‑Q200 qualified, supporting use in automotive electrical and electronic systems.
• Package & Mounting — Radial-lead can (φ16 × 25 mm), lead spacing 7.5 mm (±0.5 mm); available in bulk or bag packing for production and prototyping.
• Compliance — RoHS compliant.

Typical Applications

• Automotive power electronics — Bulk and filter capacitance for DC buses, converters and control modules where AEC‑Q200 qualification and high voltage are required.
• Power supplies — Smoothing and energy storage in high-voltage switch-mode and linear power supplies and ballast circuits.
• Industrial converters and inverters — High-voltage filtering and ripple handling in motor drives, power converters and industrial power systems.

Unique Advantages

• High-voltage capability: 450 V rating lets designers reduce component count in high-voltage stages and simplify DC bus design.
• High ripple tolerance: Specified ripple currents at both low and high frequencies support a range of switching and mains-powered topologies.
• Long life at elevated temperature: 12,000-hour endurance at 105°C helps ensure predictable service life in thermally demanding installations.
• Automotive-grade reliability: AEC‑Q200 qualification provides confidence for vehicle-level deployment and design validation.
• Compact radial package: φ16 × 25 mm can and standard 7.5 mm lead spacing make the part straightforward to integrate into through-hole assemblies and retrofit designs.
• Production-ready packaging: Available in bulk and bag packing to support both low-volume prototyping and high-volume manufacturing workflows.
