RKS1V270MCNAHJGS

The RKS1V270MCNAHJGS is a surface‑mount conductive polymer aluminum electrolytic capacitor from Nichicon’s RKS series. It delivers a 27 µF capacitance at a 35 V rating with polymer electrolyte construction designed for stable electrical performance in compact SMD packaging.

Engineered for general‑purpose power applications that demand high ripple handling and long life at elevated temperatures, this part combines low equivalent series resistance and a wide operating temperature range to support reliable filtering and decoupling in demanding environments.

Key Features

• Capacitance & Tolerance: 27 µF nominal with ±20% tolerance (specified as -20%~20%), meeting common design requirements for bulk decoupling and energy storage.
• Rated Voltage: 35 V DC rated voltage suitable for mid‑voltage power rails.
• Low Losses: Tangent of loss angle (tan δ) of 0.12 measured at 20°C, 120 Hz, indicating controlled dielectric losses for stable operation.
• Low ESR at High Frequency: ESR of 27 mΩ measured at 20°C, 100 kHz, enabling effective high‑frequency ripple attenuation and fast transient response.
• High Ripple Current Capability: Low‑frequency ripple current of 160 mA (120 Hz) and high‑frequency ripple current of 1.6 A (300 kHz), supporting high‑throughput power stages and switching regulators.
• Long High‑Temperature Life: Load life rated at 3000 hours at 125°C under rated voltage, allowing durable operation in elevated temperature environments.
• Wide Operating Temperature Range: −55°C to +125°C to cover a broad range of thermal conditions.
• Compact SMD Can Package: φ8 × 10 mm can (L: 1.0 cm × D: 0.8 cm) in a surface‑mount radial can style; supplied in embossed carrier taping with moisture‑proof packing for automated assembly.
• Leakage Current: Specified leakage current up to 100 µA after voltage application, consistent with conductive polymer aluminum electrolytic characteristics.
• RoHS Compliant: Meets RoHS requirements as stated in the product data.

Typical Applications

• Power supply filtering: Low ESR and high ripple current capability make this capacitor suitable for smoothing and decoupling on intermediate and post‑regulator rails.
• Switching regulator output stages: High‑frequency ripple current handling supports switching converter outputs and reduces voltage ripple under dynamic load.
• Embedded power modules: Compact SMD can package and long high‑temperature life suit tight‑space power modules and embedded electronics operating at elevated temperatures.

Unique Advantages

• High ripple handling: Combined 160 mA (120 Hz) and 1.6 A (300 kHz) ripple ratings enable reliable performance in both low‑ and high‑frequency power circuits.
• Fast transient response: Low ESR (27 mΩ at 100 kHz) supports rapid charge/discharge cycles for transient suppression in regulator outputs.
• Thermal endurance: 3000 hours load life at 125°C offers extended service life in thermally demanding installations.
• Compact SMD format with assembly support: φ8×10 mm can in embossed carrier taping and moisture‑proof packing simplifies automated placement and handling.
• Stable electrical characteristics: Specified tan δ of 0.12 (20°C, 120 Hz) and controlled leakage current provide predictable performance over temperature and time.
