RKS1E180MCNAHGGS

The RKS1E180MCNAHGGS is a Nichicon RKS‑series conductive polymer aluminum solid electrolytic capacitor in a surface‑mount radial (can) package. It delivers 18 µF capacitance at 25 V with low ESR and high allowable ripple current, packaged for automated assembly.

Engineered for applications that require elevated temperature capability and sustained ripple handling, this SMD capacitor offers a compact φ8 × 7.7 mm footprint, RoHS compliance, and a rated operating range from −55 °C to 125 °C with a 3000‑hour life at 125 °C.

Key Features

• Capacitance & Tolerance — 18 µF nominal with a tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Rated Voltage — 25 V DC.
• Conductive‑Polymer Electrolyte — Solid polymer construction for stable performance and long life characteristics under elevated temperature and ripple stress.
• Low Loss / Dissipation — tanδ (DF) = 0.12 specified at 20 °C, 120 Hz for predictable AC behavior.
• Low ESR for High‑Frequency Performance — ESR = 30 mΩ at 20 °C, 100 kHz, enabling efficient high‑frequency decoupling.
• High Ripple Capability — Rated ripple current: 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) for handling demanding supply transients.
• Leakage Current — Specified leakage current of 100 µA (after standard conditioning).
• Extended High‑Temperature Life — 3000 hours endurance at 125 °C under rated voltage.
• Reflow Compatible SMD Package — Surface‑mount radial can (φ8 × 7.7 mm) with embossed carrier taping and moisture‑proof packing; compatible with lead‑free reflow soldering profiles up to a 260 °C peak per datasheet guidance.
• Wide Operating Temperature — −55 °C to +125 °C.
• RoHS Compliant — Conforms to applicable RoHS directives.

Typical Applications

• Power Supply Decoupling — Local bulk and decoupling capacitance where low ESR and high ripple capability improve transient response and stability.
• DC‑DC Converters / Point‑of‑Load — High‑frequency ripple handling (1.6 A at 300 kHz) makes it suitable for smoothing outputs of switching regulators.
• Industrial and Telecom Electronics — Operation to 125 °C and a 3000‑hour rated life support sustained use in elevated‑temperature, high‑duty environments.
• Compact SMD Designs — Small φ8 × 7.7 mm footprint and SMD packaging for space‑constrained board layouts and automated assembly.

Unique Advantages

• High ripple tolerance: 1.6 A at 300 kHz and 160 mA at 120 Hz provide margin for heavy AC stress in switching applications.
• Low ESR at high frequency: 30 mΩ (100 kHz) reduces losses and improves efficiency in power circuits.
• Robust thermal endurance: Rated for −55 °C to 125 °C with 3000 hours of life at 125 °C for reliable operation in hot environments.
• SMD‑friendly packaging: Embossed carrier taping and moisture‑proof packing support high‑volume surface‑mount production and lead‑free reflow processes.
• Predictable AC behavior: Specified tanδ = 0.12 at 20 °C, 120 Hz and defined leakage current (100 µA) simplify design margining.
• Regulatory compliance: RoHS compliant for deployment in regulated markets.
