RKS1C821MCNAJJGS

The RKS1C821MCNAJJGS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon's RKS series. It delivers high capacitance (820 µF) at a 16 V rating in a compact φ10 × 10 mm SMD can for general-purpose electronic power applications.

Designed for demanding thermal and ripple environments, this part combines low ESR and high allowable ripple current with a long rated life of 3000 hours at 125°C, making it suitable for power filtering, decoupling and high‑frequency power rail stabilization in industrial and embedded systems.

Key Features

• High Capacitance / Rated Voltage — 820 µF nominal capacitance at a 16 V rating, with tolerance of -20% to +20% for bulk energy storage and smoothing.
• Low Equivalent Series Resistance (ESR) — 20 mΩ specified at 20°C/100 kHz, supporting efficient high-frequency decoupling and reduced dissipation.
• High Ripple Current Capability — 210 mA at 120 Hz (low frequency) and 2.1 A at 300 kHz (high frequency), enabling robust handling of AC ripple on power rails.
• Low Loss Tangent — tanδ = 0.12 measured at 20°C, 120 Hz, contributing to stable AC performance.
• Extended Temperature & Life — Operating range from -55°C to +125°C with an endurance rating of 3000 hours at 125°C.
• Surface-Mount Can Package — Radial can SMD (φ10 × 10 mm) in embossed carrier taping with moisture-proof packing for automated assembly and storage.
• Leakage Current — 656 µA specification for predictable standby characteristics.
• Compliance & Production Status — RoHS compliant; part is in mass production.

Typical Applications

• Power Supply Filtering — Low ESR and high ripple current make the capacitor suitable for bulk filtering on DC/DC converters and linear regulators.
• High-Frequency Decoupling — High allowable HF ripple current and low tanδ help stabilize high-speed power rails in embedded and communications equipment.
• Industrial Electronics — Long 3000 h life at 125°C and a wide -55°C to 125°C operating range support use in high-temperature industrial modules and control systems.
• General-Purpose Energy Storage — Compact SMD can form factor provides bulk capacitance for smoothing and hold-up in compact designs.

Unique Advantages

• Compact High-Capacitance SMD — 820 µF in a φ10 × 10 mm SMD can saves board area while delivering significant bulk energy storage.
• Enhanced Power-Handling — 2.1 A high-frequency ripple capability combined with 20 mΩ ESR reduces voltage ripple and thermal stress on power components.
• Robust Thermal Endurance — Rated for 3000 hours at 125°C, providing predictable lifetime and reliability in elevated-temperature environments.
• Assembly-Ready Packaging — Supplied in embossed carrier taping with moisture-proof packing to support automated pick-and-place and reflow workflows.
• Predictable Leakage Behavior — Specified leakage current (656 µA) enables accurate standby and leakage budgeting for systems with tight current budgets.
