RKS1D820MCNAHJGS

The RKS1D820MCNAHJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. It delivers 82 µF capacitance at a 20 V rating in a compact φ8 × 10 mm SMD can package intended for general-purpose electronic designs.

Designed for applications that require low ESR and high ripple handling, this part combines a low equivalent series resistance (25 mΩ at 100 kHz) with a high-frequency ripple current capability (1.7 A at 300 kHz) and a long load life of 3000 hours at 125°C.

Key Features

• Capacitance & Tolerance — 82 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 20 V DC nominal rating for power-rail and decoupling applications.
• Low ESR & High-Frequency Ripple — 25 mΩ ESR at 100 kHz and 1.7 A high-frequency ripple current (300 kHz) for improved transient and switching performance.
• Low-Frequency Ripple & Leakage — 170 mA ripple current at 120 Hz and leakage current specified at 100 µA.
• Endurance & Temperature Range — Load life of 3000 hours at 125°C; operating range from −55°C to +125°C.
• Dielectric Loss — tan δ = 0.12 (measured at 20°C, 120 Hz), supporting stable performance at rated conditions.
• Package & Mounting — Surface-mount radial can (φ8 × 10 mm); supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Reflow Compatibility — SMD type designed to meet lead‑free reflow soldering conditions up to a 260°C peak per the series datasheet.
• RoHS Compliance — RKS series is compliant to the RoHS directive as documented in the series datasheet.

Typical Applications

• Power supply decoupling — Compact SMD can for bulk and high-frequency decoupling on DC rails where low ESR (25 mΩ) and 1.7 A ripple handling improve transient response.
• DC–DC converters — Suited for switching regulator output filtering with high-frequency ripple current capability and stable performance to 125°C.
• Power management modules — Useful in compact power modules that require high capacitance density and long life (3000 hours at 125°C) under elevated temperatures.
• Industrial electronics — Reliable operation across −55°C to +125°C for general-purpose industrial designs exposed to wide temperature ranges.

Unique Advantages

• High ripple capability: 1.7 A at 300 kHz and 170 mA at 120 Hz allow handling of both switching and low-frequency ripple currents without compromising performance.
• Low ESR for improved efficiency: 25 mΩ ESR at 100 kHz reduces voltage drop and power loss in high-frequency circuits.
• Extended high-temperature life: 3000 hours endurance at 125°C provides predictable ageing characteristics for designs exposed to elevated temperatures.
• Compact SMD can: φ8 × 10 mm package gives a small footprint while delivering 82 µF capacitance for space-constrained assemblies.
• Manufacturing-ready packaging: Supplied in embossed carrier taping with moisture-proof packing for automated surface-mount placement.
• Stable dielectric behavior: tan δ = 0.12 at 20°C, 120 Hz and controlled leakage current (100 µA) support stable filtering over the rated conditions.
