RKS1D820MCNAFEGS

The RKS1D820MCNAFEGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 82 µF capacitance at a 20 V rating. Designed as a compact SMD radial can, it provides high ripple capability and stable performance across a broad temperature range for demanding power and decoupling applications.

With a rated operating range from −55 °C to 125 °C and a 3,000 hour endurance at 125 °C, this part targets applications that require reliable high-temperature operation, low equivalent series resistance, and automated assembly readiness.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a rated voltage of 20 V and tolerance −20% to +20%.
• Conductive Polymer Dielectric — Solid conductive polymer construction for stable performance under ripple and temperature stress.
• Low ESR — ESR of 50 mΩ measured at 20 °C and 100 kHz, supporting efficient high-frequency decoupling and reduced power loss.
• High Ripple Capability — Low-frequency ripple current 90 mA (120 Hz) and high-frequency ripple current 900 mA (300 kHz) for demanding power-rail filtering.
• Leakage and Dissipation — Leakage current specified at 100 µA; tan δ (DF) 0.12 measured at 20 °C, 120 Hz, 20 V.
• Robust Endurance — Load life of 3,000 hours at 125 °C under rated voltage, with defined limits for capacitance change, tan δ and ESR after endurance testing.
• SMD Package & Assembly — Compact φ6.3 mm × 5.8 mm (D × L) radial can SMD package with surface-mount land recommendation 6.6 mm × 6.6 mm; supplied in embossed carrier taping with moisture-proof packing.
• Reflow Compatibility — Designed for lead‑free reflow soldering; datasheet reflow profile supports a 260 °C peak for the specified duration.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• Power supply decoupling — High ripple current capability and low ESR make it suitable for output filtering and bulk decoupling on DC–DC converters and power rails.
• High-frequency smoothing — Low ESR at 100 kHz and specified high-frequency ripple current support smoothing in high-speed switching power stages.
• Industrial electronics — Long life at 125 °C and wide operating temperature range suit control modules and power subsystems that operate in elevated-temperature environments.
• Compact SMD modules — Small φ6.3 × 5.8 mm footprint and tape-and-reel packaging support dense board layouts and automated placement.

Unique Advantages

• Proven high-temperature endurance — Rated 3,000 hours at 125 °C to support sustained operation in hot environments and extend system field life.
• High ripple handling with low losses — 900 mA at 300 kHz and 50 mΩ ESR reduce voltage ripple and thermal dissipation on power rails.
• Compact SMD form factor — φ6.3 × 5.8 mm can and small recommended land pattern enable space-saving designs without sacrificing capacitance.
• Manufacturing-ready packaging — Embossed carrier taping and moisture-proof packing streamline surface-mount assembly and storage.
• Stable AC behavior — Specified tan δ and leakage characteristics measured at 20 °C / 120 Hz provide predictable performance for filter and decoupling networks.
