Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 80 V and capacitance tolerance of -20% to +20%.
• Low ESR & High Ripple Current — ESR specified at 35 mΩ (measured at 100 kHz, 20 °C); ripple-current capability of 2.7 A at 100 kHz and 1.35 A at 120 Hz.
• High-Temperature Endurance — Long life: 4000 hours at 125 °C under rated conditions; endurance specifications and post-test limits are defined in the datasheet.
• Wide Operating Temperature — Rated for operation from -55 °C to +125 °C with tight impedance stability (Z(+125 °C)/Z(+20 °C) ≤ 1.25 and Z(-55 °C)/Z(+20 °C) ≤ 1.25 at 100 kHz).
• Automotive-Grade Qualification — AEC-Q200 compliant for designs requiring automotive-level reliability.
• SMD Assembly Ready — Chip-type can package suitable for surface-mount soldering; compatible with lead-free reflow soldering up to a 260 °C peak under the manufacturer’s recommended profile.
• Leakage Current — After 2 minutes at rated voltage, leakage current is specified as not more than 0.03 CV (conditioning details in datasheet).
• Compact Package — Physical size L: 1.2 cm × D: 0.8 cm with recommended land pattern 8.3 mm × 8.3 mm; radial can SMD construction.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Power Electronics — Use in vehicle power rails and power conversion circuits where AEC-Q200 qualification and high-temperature endurance are required.
• DC-DC Converters and Power Supplies — Bulk filtering and smoothing where low ESR and high ripple-current capability reduce losses and temperature rise.
• Engine Control and ECU Modules — Reliable decoupling and energy buffering across a wide temperature range for control electronics.
• Infotainment and On-board Electronics — Stabilizing power rails in systems that require compact SMD capacitors with robust thermal and mechanical assembly characteristics.

Unique Advantages

• Automotive-ready reliability: AEC-Q200 compliance and a 4000-hour life at 125 °C provide documented endurance for vehicle-grade designs.
• Reduced ripple losses: Low ESR (35 mΩ at 100 kHz) combined with high ripple-current ratings helps minimize heating in power circuits.
• Wide temperature stability: Specified operation from -55 °C to +125 °C with controlled impedance ratios supports reliable performance across extremes.
• SMD-friendly package: Chip/can form factor with defined land pattern and lead-free reflow compatibility simplifies PCB assembly and process integration.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements.
