RKS1C181MCNAJLGS

The RKS1C181MCNAJLGS from Nichicon is a surface-mount conductive-polymer aluminum solid electrolytic capacitor optimized for high-capacitance, high-ripple applications. It delivers 180 µF at a 16 V rated voltage in a compact φ10 × 12.4 mm SMD can, designed for general-purpose electronic power applications that require low ESR, long life, and wide operating temperature range.

Key value propositions include a low ESR of 20 mΩ (measured at 100 kHz, 20°C), broad temperature capability from −55°C to 125°C, and a demonstrated load life of 3000 hours at 125°C—making it suitable where sustained ripple handling and thermal endurance are needed.

Key Features

• Capacitance and Voltage — 180 µF nominal capacitance at a rated voltage of 16 V, with a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Conductive-Polymer Construction — Solid conductive-polymer electrolyte for stable performance and measurable low-loss characteristics (tanδ = 0.12 at 20°C, 120 Hz).
• Low ESR and High-Frequency Performance — ESR of 20 mΩ at 100 kHz (20°C) and high-frequency ripple capability of 2.0 A at 300 kHz for demanding switching environments.
• Ripple Current Handling — 200 mA low-frequency ripple current rating at 120 Hz and 2.0 A high-frequency ripple current rating at 300 kHz to support input/output smoothing and decoupling in power stages.
• Wide Temperature and Long Life — Operating range −55°C to +125°C with a rated endurance of 3000 hours at 125°C, supporting extended operation under elevated temperature stress.
• Surface-Mount Package and Packaging — Radial can SMD package (φ10 × 12.4 mm) supplied in embossed carrier taping with moisture-proof packing for pick-and-place assembly.
• Leakage Current — Specified leakage current of 144 µA, suitable for many power and decoupling use cases where controlled leakage is required.
• Regulatory — RoHS compliant.

Typical Applications

• Power Supply Decoupling: Bulk and output smoothing for DC–DC converters and point-of-load regulators, leveraging high capacitance and low ESR to reduce voltage ripple.
• SWITCH-MODE POWER SUPPLIES: Input filtering in switching power stages where high-frequency ripple current capability and low loss are required.
• Embedded Power Modules: Local energy storage and transient support in compact surface-mount power modules operating across wide temperature ranges.

Unique Advantages

• High Capacitance in Compact SMD Can: 180 µF in a φ10 × 12.4 mm package provides significant bulk capacitance for space-constrained board designs.
• Low ESR for Improved Efficiency: 20 mΩ ESR at 100 kHz reduces dissipation and supports higher ripple currents, improving regulator stability and thermal performance.
• High-Frequency Ripple Capability: 2.0 A rating at 300 kHz enables reliable use directly at switching-node frequencies common in modern power converters.
• Long Thermal Endurance: 3000 hours at 125°C endurance rating allows designers to plan for extended operating life under elevated temperature conditions.
• Surface-Mount Assembly Ready: Embossed carrier taping with moisture-proof packing for automated placement and handling.
• Controlled Leakage and Loss: Specified leakage current (144 µA) and tanδ (0.12 at 20°C, 120 Hz) facilitate predictable behavior in bias and timing-sensitive circuits.
