• High Allowable Ripple Current — Low-frequency ripple current of 140 mA (120 Hz) and high-frequency ripple current of 1.4 A (300 kHz) to handle switching and ripple loads.
• High Temperature Endurance — Operating temperature range from −55 °C to 125 °C with an endurance rating of 3000 hours at 125 °C, supporting sustained elevated-temperature operation.
• Leakage and Loss Characteristics — Leakage current specified at 100 µA and tan δ (dissipation factor) of 0.12 measured at 20 °C, 120 Hz.
• SMD Package & Reflow Compatibility — Compact radial can SMD package (φ6.3 × 7.7 mm) with surface-mount land size L: 6.6 × W: 6.6 mm; designed for lead-free reflow soldering with peak temperature up to 260 °C per datasheet soldering profile.
• RoHS Compliant & Production Ready — RoHS compliant and listed as in mass production by the manufacturer.

Typical Applications

• DC–DC Converters — Bulk and output filtering for switching regulators where low ESR and high ripple handling improve transient response and efficiency.
• Power Supply Filtering — Input/output smoothing in industrial and telecommunications power modules that operate at elevated temperatures.
• High-Frequency Power Modules — Decoupling and stabilization for point-of-load and high-frequency switching circuits leveraging the capacitor’s low ESR at 100 kHz.
• Embedded Industrial Electronics — Compact SMD form factor for space-constrained boards that require robust performance across −55 °C to 125 °C.

Unique Advantages

• Extended High-Temperature Life: 3000 hours at 125 °C provides predictable aging characteristics for designs with sustained high ambient temperatures.
• High-Frequency Performance: 35 mΩ ESR at 100 kHz and 1.4 A ripple at 300 kHz support aggressive switching topologies and tight voltage regulation.
• Compact SMD Footprint: φ6.3 × 7.7 mm can size reduces board area while maintaining high capacitance and ripple capability.
• Reflow-Ready Process Compatibility: Designed for lead-free reflow soldering up to 260 °C peak, easing assembly integration into modern SMT production flows.
• Predictable Leakage and Dissipation: Specified leakage current (100 µA) and tan δ (0.12 at 20 °C, 120 Hz) allow predictable power-loss budgeting in designs.
• Production Availability: Nichicon mass-production status supports procurement stability for volume designs.
