RKS1H820MCNAJLGS

The RKS1H820MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers 82 µF capacitance at a 50 V rating in a compact radial SMD can (φ10 × 12.4 mm), designed for general-purpose power applications.

Engineered for high ripple environments and elevated operating temperatures, this part combines low ESR, defined high-frequency ripple capability, and a long load life to support robust power delivery and decoupling in demanding electronic designs.

Key Features

• Capacitance & Voltage — 82 µF rated capacitance with tolerance of -20% to +20% at 20°C, 120 Hz; rated voltage 50 V.
• Low ESR & High-Frequency Performance — ESR of 25 mΩ measured at 20°C/100 kHz and a high-frequency ripple current rating of 1.6 A at 300 kHz, supporting effective high-speed decoupling.
• Ripple Current (Dual-Frequency) — Low-frequency ripple current 160 mA at 120 Hz and high-frequency ripple current 1.6 A at 300 kHz for broad-spectrum ripple handling.
• Thermal Endurance & Lifetime — Operating temperature range from -55°C to 125°C with rated load life of 3000 hours at 125°C.
• Loss and Leakage Characteristics — Tangent of loss angle (tanδ) of 0.12 (20°C, 120 Hz) and leakage current specified at 205 µA, enabling predictable electrical behavior.
• Surface-Mount Packaging — Radial can SMD package (φ10 × 12.4 mm / L: 1.24 cm × D: 1.00 cm) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Manufacturing Compatibility & Compliance — Compatible with lead-free reflow soldering profiles up to a 260°C peak per datasheet guidance and RoHS compliant.

Typical Applications

• Power Supply Output Filtering — Use on DC power rails to smooth output ripple and stabilize regulator outputs where low ESR and high ripple handling are required.
• DC–DC Converter Outputs — Suitable for output-stage decoupling in switching converters thanks to its high-frequency ripple current capability and low ESR.
• High-Frequency Decoupling — Effective for decoupling near switching devices and high-speed power components where performance at 100–300 kHz is important.
• Industrial and Embedded Electronics — Designed for general-purpose applications requiring wide temperature range operation and long lifetime at elevated temperatures.

Unique Advantages

• High ripple current capacity: 1.6 A at 300 kHz enables reliable handling of switching currents in converter and regulator outputs.
• Low ESR for improved transient response: 25 mΩ at 100 kHz reduces voltage droop and heat generation under dynamic loads.
• Wide temperature and proven endurance: −55°C to 125°C rating with 3000 hours life at 125°C supports long-term stability in high-temperature environments.
• Compact SMD can footprint: φ10 × 12.4 mm package provides a space-efficient solution for automated assembly while maintaining substantial capacitance and ripple capability.
• Assembly-ready supply: Embossed carrier taping and moisture-proof packing simplify handling and placement in production lines.
