Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 16 V nominal voltage; capacitance tolerance is −20% to +20% (measured at 20°C, 120 Hz).
• Low Loss / Electrical Performance — Loss tangent (tanδ) specified at 0.12 (20°C, 120 Hz) and ESR of 25 mΩ at 20°C / 100 kHz, supporting efficient energy transfer with reduced dissipation.
• Ripple Current Capability — Low-frequency ripple current of 170 mA at 120 Hz and high-frequency ripple current of 1.7 A at 300 kHz, suitable for applications with substantial AC ripple content.
• Leakage Current — Specified leakage current of 176 µA after rated voltage application, supporting predictable bias behavior in power circuits.
• High-Temperature Endurance — Rated lifetime of 3000 hours at 125°C under rated voltage, with endurance characteristics defined by the RKS series datasheet.
• Package & Mounting — Surface-mount, radial can SMD package (φ8 × 10 mm); supplied in embossed carrier taping with moisture-proof packing for automated assembly and storage.
• Process Compatibility & Compliance — SMD type compatible with lead-free reflow soldering conditions up to a 260°C peak and compliant with RoHS requirements.

Typical Applications

• Power Supply Filtering — Bulk and post-regulation smoothing where 220 µF capacitance and robust ripple handling reduce voltage ripple on DC rails.
• DC–DC Converter Output Decoupling — Local energy storage and high-frequency ripple suppression for switching regulator outputs benefiting from low ESR and high-frequency ripple rating.
• Industrial Power Modules — Board-level decoupling in systems that must withstand elevated operating temperatures, leveraging the 3000-hour life at 125°C.
• General Purpose Electronics — SMD-capacitor solution for appliances and equipment requiring compact size, RoHS compliance, and automated placement readiness.

Unique Advantages

• High ripple tolerance: Specified high-frequency ripple current of 1.7 A (300 kHz) and low-frequency ripple of 170 mA (120 Hz) enable use in ripple-intensive power circuits.
• Low ESR: 25 mΩ ESR at 100 kHz reduces conduction losses and improves converter stability and thermal performance on the PCB.
• Extended high-temperature life: 3000 hours at 125°C under rated conditions gives designers quantifiable endurance for thermally demanding applications.
• Compact SMD form factor: φ8 × 10 mm can-style SMD package offers a small footprint for space-constrained board layouts while supporting automated assembly.
• Manufacturing-friendly: Lead-free reflow compatibility to 260°C peak and embossed carrier taping with moisture-proof packing streamline surface-mount process integration.
• Predictable electrical characteristics: Defined tanδ, leakage current, and tolerance values allow accurate margining in power and decoupling designs.
