RKS1C181MCNAFGGS

The RKS1C181MCNAFGGS is a surface-mount, conductive polymer aluminum electrolytic capacitor from Nichicon’s RKS series. It delivers 180 µF of capacitance at a 16 V rating in a compact φ6.3 × 7.7 mm can-style SMD package.

Designed for general-purpose power applications, this part combines low ESR, high allowable ripple current, and extended thermal endurance to support high-frequency power circuitry and robust operation across a wide temperature range.

Key Features

• Capacitance & Voltage: 180 µF nominal capacitance with a rated voltage of 16 V and a tolerance of -20% to +20%.
• Low ESR & High-Frequency Performance: ESR of 30 mΩ measured at 20°C/100 kHz and a high-frequency ripple current rating of 1.5 A (300 kHz) for efficient power delivery in switching environments.
• Ripple Handling: Low-frequency ripple current rated at 150 mA (120 Hz) to support both low- and high-frequency ripple demands.
• Thermal Endurance: Rated operating temperature from -55°C to +125°C with a load life of 3000 hours at 125°C, supporting prolonged use in high-temperature applications.
• Leakage & Loss Characteristics: Leakage current specified at 144 µA; tanδ (dissipation factor) 0.12 at 20°C/120 Hz for predictable loss behavior.
• Package & Assembly: φ6.3 × 7.7 mm radial can-style SMD package supplied in embossed carrier taping with moisture-proof packing for automated placement and mass-production readiness.
• Compliance: RoHS‑compliant per product data.

Typical Applications

• General Purpose Power Circuits: Bulk capacitance and low ESR make this part suitable for decoupling and energy storage where 16 V systems require robust SMD capacitors.
• High-Frequency Power Stages: The 1.5 A high-frequency ripple rating and 30 mΩ ESR support switching converters and high-frequency power electronics.
• Thermally Demanding Environments: With a -55°C to +125°C operating range and 3000 h life at 125°C, it is appropriate for designs exposed to sustained high temperature.

Unique Advantages

• High Allowable Ripple Current: 1.5 A at high frequency reduces thermal stress in switching applications and supports higher power density designs.
• Low ESR: 30 mΩ at 100 kHz minimizes losses and voltage drop under dynamic load, improving efficiency in power delivery.
• Long Thermal Life: 3000 hours at 125°C provides extended operational reliability where elevated ambient or board temperatures are common.
• Compact SMD Can: φ6.3 × 7.7 mm package delivers high capacitance in a small footprint suitable for space‑constrained boards and automated assembly.
• Assembly-Ready Packaging: Embossed carrier taping and moisture-proof packing streamline pick-and-place and protect components during storage and reflow processes.
• Predictable Leakage and Loss: Specified leakage current (144 µA) and tanδ (0.12) support predictable behavior in powered systems and simplify margining during design.
