RKS1V271MCNAJJGS

The RKS1V271MCNAJJGS from Nichicon is a surface-mount conductive polymer aluminum electrolytic capacitor offering 270 µF capacitance at a 35 V rating. Built for general-purpose power applications, it delivers low ESR and high allowable ripple current in a compact φ10×10 mm SMD can.

Engineered for reliability across a wide temperature span (−55 °C to 125 °C) and a long load life (3000 hours at 125 °C), this capacitor addresses high-frequency decoupling and bulk energy storage requirements in space-constrained assemblies.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design providing stable electrical performance and low equivalent series resistance.
• Capacitance and tolerance — 270 µF with tolerance of −20% to +20% at 20 °C, 120 Hz.
• Voltage rating — 35 V rated voltage suitable for a range of mid-voltage power rails.
• Low ESR — ESR of 20 mΩ measured at 20 °C, 100 kHz, enabling efficient high-frequency performance.
• High allowable ripple current — 200 mA at 120 Hz (low frequency) and 2 A at 300 kHz (high frequency) for robust ripple-handling capabilities.
• Loss tangent — tan δ of 0.12 measured at 20 °C, 120 Hz for predictable AC behavior.
• Leakage current — Specified leakage current of 472 µA after voltage application.
• Long endurance — Rated load life of 3000 hours at 125 °C under rated voltage.
• Compact SMD package — φ10 × 10 mm (1.0 × 1.0 cm) radial can SMD footprint with embossed carrier taping and moisture-proof packing for assembly readiness.
• Wide operating temperature — −55 °C to +125 °C to support challenging thermal environments.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Power supply decoupling: Low ESR and high ripple current capability make this capacitor suitable for smoothing and decoupling on DC power rails.
• High-frequency filtering: Excellent performance at 100 kHz–300 kHz supports high-frequency noise suppression in switching regulator circuits.
• Compact electronics: Small φ10×10 mm SMD can provides bulk capacitance in space-constrained assemblies where board area is limited.
• Industrial and commercial electronics: Wide temperature range and 3000-hour life at 125 °C support robust operation in demanding environments.

Unique Advantages

• Reduced heat generation: Low ESR (20 mΩ) minimizes power loss during high-current operation, lowering thermal stress on the capacitor and surrounding components.
• Improved ripple handling: High allowable ripple currents (up to 2 A at high frequency) reduce the need for parallel components to meet ripple requirements.
• Long-term reliability: 3000-hour endurance at 125 °C provides predictable aging characteristics for long-life designs.
• Compact, assembly-ready package: SMD radial can with embossed carrier taping and moisture-proof packing streamlines automated placement and storage handling.
• Wide temperature operation: −55 °C to +125 °C operation supports deployment across diverse environmental conditions.
• Regulatory compliance: RoHS compliance eases integration into products requiring restricted-substance adherence.
