RKS1H270MCNAHFGS

The RKS1H270MCNAHFGS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount radial can package. It delivers 27 µF at 50 V with low equivalent series resistance and rated ripple performance for demanding power applications.

Designed for surface-mount assembly and lead‑free reflow processes, this capacitor targets power-management and electronic systems that require low ESR, high ripple capability, and extended high‑temperature endurance.

Key Features

• Capacitance & Tolerance — 27 µF nominal with tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Rated Voltage — 50 V DC rating for mid-voltage power rails.
• Low ESR — 30 mΩ measured at 20°C/100 kHz, supporting improved voltage stability and reduced loss in filtering applications.
• High Ripple Current — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency), suitable for switching regulator filtering and high-frequency decoupling.
• Leakage Current — Specified at 100 µA, enabling controlled standby current in power circuits.
• Extended High‑Temperature Life — Rated for 3,000 hours at 125°C, supporting long-term operation in elevated-temperature environments.
• Wide Operating Temperature — −55°C to +125°C operating range for use across a broad set of thermal conditions.
• Surface-Mount Package — φ8 × 6.7 mm can (SMD radial can); surface-mount land size 8.3 × 8.3 mm, supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Assembly Compatibility — Compatible with lead‑free reflow soldering (peak 260°C) per the product series soldering specification.

Typical Applications

• Power Conversion (DC‑DC converters) — Low ESR (30 mΩ) and 1.6 A high‑frequency ripple current make this capacitor suitable for output filtering and stability in switching regulators.
• Input Filtering for Power Modules — 27 µF capacitance with controlled leakage supports bulk decoupling at mid-voltage inputs to smooth supply rails.
• Industrial Power Electronics — 3,000‑hour life at 125°C and −55°C to +125°C range enable deployment in equipment exposed to elevated ambient temperatures.
• High‑Frequency Decoupling — Low ESR at 100 kHz and specified HF ripple current support high‑frequency noise suppression for power and mixed-signal circuits.

Unique Advantages

• Low-loss performance: 30 mΩ ESR at 100 kHz reduces dissipative losses and improves regulator efficiency under load.
• High ripple tolerance: Specified LF and HF ripple ratings (160 mA at 120 Hz, 1.6 A at 300 kHz) allow reliable operation with fast switching supplies.
• Robust high‑temperature endurance: 3,000 hours at 125°C gives designers predictable long-term behavior in thermally stressed environments.
• Surface-mount convenience: Compact φ8 × 6.7 mm SMD radial can and embossed carrier taping streamline automated assembly and board layout.
• Lead‑free reflow compatibility: Peak 260°C reflow support aligns with modern lead‑free manufacturing processes.
• Controlled leakage: 100 µA leakage current specification aids in maintaining low standby currents in power-sensitive designs.
