RKS1C221MCNAHFGS

The RKS1C221MCNAHFGS from Nichicon is a surface-mount conductive-polymer aluminum electrolytic capacitor in the RKS series, providing 220 µF capacitance at a 16 V rating. Engineered for general-purpose electronic designs, it combines low equivalent series resistance (ESR) and high allowable ripple current in a compact φ8 × 6.7 mm SMD can.

Key value propositions include low ESR (30 mΩ at 100 kHz) for improved high-frequency performance, robust thermal endurance (3,000 hours at 125°C), and a wide operating temperature range from −55°C to 125°C—delivering dependable smoothing, decoupling and bulk capacitance in compact assemblies.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance rated at 16 V with a tolerance of −20% to +20% for predictable charge storage in power rails.
• Low ESR & High Ripple Handling — ESR specified at 30 mΩ (20°C, 100 kHz) with low-frequency ripple current of 160 mA (120 Hz) and high-frequency ripple current of 1.6 A (300 kHz), supporting demanding AC and switching environments.
• Thermal Endurance — Load life rated to 3,000 hours at 125°C, providing long-term stability in elevated-temperature applications.
• Wide Temperature Range — Operates from −55°C to 125°C to accommodate harsh ambient conditions and industrial temperature swings.
• Polarized SMD Can Package — Compact radial can SMD package (φ8 × 6.7 mm) designed for surface-mount assembly and embossed carrier taping with moisture-proof packing for automated production.
• Leakage and Loss Characteristics — Leakage current of 176 µA and tan δ (DF) of 0.12 measured at 20°C, 120 Hz, enabling predictable loss and standby current behavior.
• Standards & Compliance — RoHS compliant and manufactured for mass-production availability in the Nichicon RKS series.

Typical Applications

• General-purpose power filtering — Compact SMD form factor and low ESR make the capacitor suitable for smoothing and decoupling in board-level power distribution.
• Switching regulator support — High-frequency ripple current capability supports switching converter input/output filtering in space-constrained layouts.
• Industrial and embedded electronics — Wide operating temperature range (−55°C to 125°C) and 3,000-hour high-temperature endurance suit long-life embedded controllers and industrial modules.

Unique Advantages

• High ripple tolerance: Specified low-frequency and high-frequency ripple currents (160 mA / 1.6 A) reduce heating and extend service life in switching environments.
• Low-loss performance: 30 mΩ ESR at 100 kHz and tan δ of 0.12 (20°C, 120 Hz) lower AC losses and improve efficiency where dynamic currents are present.
• Compact SMD can: φ8 × 6.7 mm package delivers high capacitance in a small footprint for dense PCB layouts and automated placement.
• Robust thermal reliability: 3,000 hours endurance at 125°C provides predictable long-term behavior for high-temperature deployments.
• Controlled leakage: Leakage current spec of 176 µA supports predictable standby and bias behaviors in power-sensitive designs.
• Production-ready packaging: Embossed carrier taping and moisture-proof packing simplify integration into automated assembly lines.
