RKS1D271MCNAHJGS

The RKS1D271MCNAHJGS from Nichicon is a surface-mount, conductive polymer aluminum solid electrolytic capacitor in the RKS series. It delivers 270 µF capacitance at a 20 V rating with a polarized SMD can package designed for compact, high-capacitance applications.

Engineered for general-purpose power and decoupling use, this part combines low ESR and high allowable ripple current with extended high-temperature endurance for reliable operation across -55°C to 125°C environments.

Key Features

• Construction: Conductive polymer aluminum solid electrolytic, surface-mount (SMD) can—polarized design for compact, high-density board layouts.
• Capacitance & Tolerance: 270 µF with tolerance of -20% to +20% measured at 20°C, 120 Hz.
• Rated Voltage: 20 V DC rating suitable for low-voltage power rails and decoupling tasks.
• Low ESR & High Ripple Handling: ESR of 25 mΩ at 20°C/100 kHz and ripple current capability of 170 mA at 120 Hz and 1.7 A at 300 kHz, supporting high-frequency switching applications.
• Thermal Endurance: Rated for operation from -55°C to 125°C with a load life of 3000 hours at 125°C.
• Dissipation Factor: tan δ = 0.12 (measured at 20°C, 120 Hz), indicating low loss for improved efficiency in AC conditions.
• Leakage Current: Specified leakage current of 270 µA (after standard conditioning), enabling predictable bias behavior in charged circuits.
• Assembly & Packaging: φ8 × 10 mm can size (L: 1.0 cm × D: 0.8 cm), supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow soldering (peak 260°C per series guidance).
• Compliance: RoHS compliant as specified for the RKS series.

Typical Applications

• Switching Power Supplies: Bulk and output filtering where high ripple current capacity and low ESR reduce loss and heat under switching conditions.
• DC-DC Converters / Point-of-Load Modules: Local decoupling for converters requiring compact SMD capacitors with stable performance at high frequency.
• Embedded & Industrial Electronics: General-purpose power smoothing in compact boards subject to wide temperature ranges and long-life thermal stress.

Unique Advantages

• High ripple-current capability: Rated for 1.7 A at high frequency (300 kHz) and 170 mA at 120 Hz, enabling robust performance in switching environments.
• Low ESR (25 mΩ): Minimizes voltage drop and thermal dissipation, improving converter efficiency and stability.
• Extended high-temperature life: 3000 hours at 125°C supports long-term reliability in thermally demanding applications.
• Compact SMD can: φ8 × 10 mm form factor provides high capacitance in a small board footprint for space-constrained designs.
• Predictable AC performance: tan δ = 0.12 at 120 Hz and defined leakage current (270 µA) help designers size filters and bias networks with confidence.
• Assembly-friendly packaging: Embossed carrier taping and moisture-proof packing support automated placement and reflow assembly flows.
