• Capacitance & Tolerance 100 µF nominal with tolerance of -20% to +20% (specified at 120 Hz, 20°C).
• Voltage Rating Rated at 6.3 V with corresponding surge characteristics per product family specifications.
• Low ESR & High Ripple Handling ESR of 24 mΩ measured at 20°C/100 kHz, with rated ripple currents of 250 mA at 120 Hz and 2.5 A at 300 kHz.
• Loss Characteristics tanδ (DF) of 0.12 at 20°C/120 Hz, supporting low-loss operation in AC and switching environments.
• Reliability & Endurance Load life of 2000 hours at 105°C; leakage current specified at 300 µA after standard conditioning.
• Package & Assembly Compact φ5 × 5.7 mm case (L × D), surface-mount radial can with embossed carrier taping and moisture-proof packing. Compatible with lead-free reflow peak conditions (260°C) as indicated for the series.
• Environmental Compliance RoHS compliant and supplied in mass-production quantities by Nichicon.

Typical Applications

• General-purpose electronics — Bulk and decoupling capacitance in compact, space-constrained PCBs where a polarized SMD solution is required.
• Switching power supplies — Output filtering for high-frequency converters using the part’s 2.5 A ripple capability at 300 kHz and low ESR.
• Power rail decoupling — Local decoupling and smoothing on DC power rails, leveraging 100 µF capacitance and low loss for improved stability.
• High-frequency power conditioning — Applications that demand reliable performance at kilohertz-to-hundred-kilohertz switching frequencies, supported by ESR measured at 100 kHz and ripple specs at 300 kHz.

Unique Advantages

• Low ESR for improved efficiency: 24 mΩ at 20°C/100 kHz reduces AC loss and heat generation in high-frequency applications.
• High ripple-current capability: Rated for 2.5 A at 300 kHz (and 250 mA at 120 Hz), enabling effective handling of switching currents and ripple energy.
• Compact SMD radial-can footprint: φ5 × 5.7 mm case provides significant capacitance in a small board area.
• Elevated-temperature endurance: 2000 hours at 105°C supports designs exposed to sustained thermal stress.
• Production-ready packaging: Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow peaks, facilitating automated assembly.
• Regulatory compliance and supply status: RoHS compliant and available in mass-production from Nichicon.
