RKS1J820MCNAJJGS

The RKS1J820MCNAJJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It provides 82 µF capacitance at a 63 V rating in a compact φ10×10L SMD can package, designed for general-purpose electronic applications.

Key value propositions include low LC and high allowable ripple current, low ESR at high frequency, and extended load life (3000 hours at 125°C), delivering reliable power handling and thermal endurance for board-level designs.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a rated voltage of 63 V and capacitance tolerance of -20% to +20%.
• Conductive Polymer Electrolyte — Conductive polymer aluminum solid electrolytic construction as specified for the RKS series, enabling low LC and high allowable ripple current.
• Low ESR & High Frequency Performance — ESR of 30 mΩ measured at 20°C/100 kHz and a tanδ of 0.12 (20°C, 120 Hz), supporting stable high-frequency operation.
• Ripple Current Capability — Low-frequency ripple current of 140 mA (120 Hz) and high-frequency ripple current of 1.4 A (300 kHz), suited to demanding ripple environments.
• Long Load Life & Temperature Range — Rated load life of 3000 hours at 125°C and operating temperature range from -55°C to +125°C.
• Leakage Current — Specified leakage current of 258 µA after rated voltage application.
• Surface-Mount Packaging — Radial, can SMD package (φ10×10L) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Manufacturing Status & Compliance — Mass production status and RoHS compliant as indicated in the product data.

Typical Applications

• General-purpose electronic designs — Use where a compact 82 µF, 63 V surface-mount capacitor is required for board-level power stages.
• SMD power modules and DC–DC converters — Low ESR and high ripple-current capability address filtering and decoupling needs in power conversion circuits.
• High-temperature environments — Rated for operation up to 125°C with a 3000-hour life specification at 125°C for thermal endurance in demanding assemblies.

Unique Advantages

• High ripple handling: Specified low-frequency and high-frequency ripple currents (140 mA @120 Hz, 1.4 A @300 kHz) reduce stress on power rails and support filtering in noisy environments.
• Low high-frequency ESR: 30 mΩ at 100 kHz helps maintain stable performance in fast-switching circuits and reduces dissipation at high frequency.
• Extended thermal endurance: 3000-hour load life at 125°C provides predictable aging behavior for long-term thermal reliability.
• Surface-mount convenience: Radial SMD can in embossed carrier taping and moisture-proof packing simplifies automated placement and handling.
• Clear performance parameters: Measured tanδ, leakage current, and ESR values give engineers specific targets for design validation and margin planning.
