RKS1E270MCNAHHGS

The RKS1E270MCNAHHGS from Nichicon is a surface-mount conductive‑polymer aluminum solid electrolytic capacitor in the RKS series. It delivers 27 µF capacitance at 25 V with low ESR and high allowable ripple current for compact, high-frequency power designs.

Engineered for elevated operating temperatures and extended life, this SMD radial-can capacitor supports lead‑free reflow processes and offers a 3000‑hour endurance rating at 125°C, making it suitable for demanding industrial and embedded power applications that require stable filtering and decoupling under thermal stress.

Key Features

• Conductive‑polymer aluminum construction — Solid electrolyte formulation for low-loss performance and improved ripple handling compared with traditional electrolytes.
• Capacitance & tolerance — 27 µF nominal with ±20% tolerance at 120 Hz, 20°C for predictable bulk and decoupling capacitance.
• Rated voltage & polarization — 25 V rated, polarized SMD radial can designed for standard polarized capacitor use.
• Low ESR & tan δ — ESR of 30 mΩ measured at 20°C/100 kHz and tan δ of 0.12 at 20°C/120 Hz to minimize loss and improve high‑frequency stability.
• High ripple capability — 160 mA at 120 Hz and 1.6 A at 300 kHz low/high frequency ripple current ratings to support switching converters and high‑frequency loads.
• Wide temperature & long life — Operating range −55°C to +125°C with a rated load life of 3000 hours at 125°C for thermal robustness.
• SMD compatible, lead‑free reflow — Designed for surface‑mount assembly and compatible with lead‑free reflow soldering up to 260°C peak per Nichicon reflow conditions.
• Compact package & tape packaging — φ8 × 8.7 mm can (L × D) with recommended land pattern 8.3 × 8.3 mm; supplied on embossed carrier taping with moisture‑proof packing for automated placement.
• Leakage current — Specified leakage current up to 100 µA after standard conditioning.

Typical Applications

• Switching power supplies — Bulk and output filtering where low ESR and high ripple handling reduce losses and improve transient response.
• Point‑of‑load decoupling — Local energy storage for DC‑DC converters and high‑frequency regulators benefiting from low impedance at high frequency.
• Industrial embedded systems — Power conditioning in compact assemblies that require extended life at elevated temperatures (3000 h at 125°C).

Unique Advantages

• Low-loss operation: 30 mΩ ESR at 100 kHz and tan δ 0.12 reduce dissipation and heat generation in high-frequency circuits.
• High ripple endurance: 1.6 A HF ripple rating supports demanding switching loads and improves reliability of power rails.
• Thermal durability: −55°C to +125°C range and 3000‑hour life at 125°C provide predictable performance in hot environments.
• Assembly-ready packaging: Embossed carrier taping with moisture‑proof packing and lead‑free reflow compatibility simplify automated SMD production.
• Compact SMD radial can: φ8 × 8.7 mm footprint with a defined land pattern enables dense board layouts without sacrificing capacitance.
