RKS1C181MCNAHHGS

The RKS1C181MCNAHHGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor providing 180 µF at a 16 V rating. It combines high capacitance in a compact SMD radial-can package (φ8 × 8.7 mm) with a broad operating temperature range and long load life for general-purpose electronic assemblies.

Designed for applications that require robust ripple handling, low equivalent series resistance, and extended endurance, this part is suited to assemblies where stable capacitance and reliability at elevated temperatures are required.

Key Features

• Capacitance & Voltage: 180 µF rated at 16 V with tolerance ±20% (–20% to +20%), providing high capacitance for decoupling and bulk energy storage in compact footprints.
• Conductive Polymer Electrolyte: Solid electrolyte construction for enhanced stability and long-term performance compared to liquid electrolytes.
• Low ESR: ESR of 30 mΩ measured at 20 °C / 100 kHz, enabling improved high-frequency performance and reduced heat generation under ripple load.
• Ripple Current Capability: Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) to support varying ripple conditions.
• Leakage Current: Specified leakage current of 144 µA for predictable standby and bias behavior.
• High-Temperature Endurance: Rated endurance of 3000 hours at 125 °C, with an operating temperature range from –55 °C to +125 °C for sustained performance in hot environments.
• Package & Mounting: Surface-mount radial can (φ8 × 8.7 mm) supplied in embossed carrier taping with moisture-proof packing to support automated assembly processes.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• General-purpose electronic assemblies: Ideal where compact, high-capacitance SMD components are required for smoothing and energy storage in board-level designs.
• High-temperature environments: Suited to designs that demand stable capacitance and endurance at elevated ambient temperatures up to 125 °C.
• High ripple current circuits: Appropriate for assemblies experiencing significant ripple currents given its specified low-frequency and high-frequency ripple ratings.

Unique Advantages

• Extended load life at elevated temperature: 3000 hours at 125 °C provides predictable long-term performance in demanding thermal conditions.
• Low ESR for efficient smoothing: 30 mΩ (100 kHz) minimizes loss and thermal stress under AC ripple, benefiting power integrity in high-frequency circuits.
• Strong ripple-handling capability: High-frequency ripple current rating of 1.6 A and low-frequency rating of 160 mA support varied ripple profiles.
• Compact SMD radial-can form factor: φ8 × 8.7 mm package delivers high capacitance in a small assembly-friendly footprint with embossed carrier taping.
• Predictable leakage and loss characteristics: Specified leakage current (144 µA) and tan δ (0.12 at 20 °C, 120 Hz) enable reliable bias and loss budgeting in designs.
• RoHS compliance: Environmentally compliant for use in regulated production environments.
