RKS1H270MCNAHHGS

The RKS1H270MCNAHHGS is a surface-mount conductive-polymer aluminum electrolytic capacitor from Nichicon's RKS series, delivering 27 µF capacitance at a 50 V rated voltage. Its low ESR and high allowable ripple current enable stable decoupling and energy-storage performance in compact SMD designs.

Designed for operation from –55°C to 125°C and rated for 3,000 hours at 125°C, this capacitor targets applications that require sustained performance at elevated temperatures and high-frequency ripple handling while fitting a small φ8 × 8.7 mm can footprint.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance with a 50 V rated voltage and ±20% capacitance tolerance for predictable energy storage in power circuits.
• Low ESR — 30 mΩ ESR measured at 20°C/100 kHz, reducing voltage drop and improving efficiency in high-frequency power stages.
• High Ripple Capability — 1.6 A high-frequency ripple current (300 kHz) and 160 mA low-frequency ripple current (120 Hz) to support switching converters and power-supply smoothing.
• Leakage Current — Leakage current specified at 100 µA to help maintain low quiescent currents in sensitive circuits.
• High-Temperature Endurance — Rated life of 3,000 hours at 125°C to support long-term reliability in elevated-temperature environments.
• Surface-Mount Radial Can — Compact φ8 × 8.7 mm SMD can (radial, can - SMD) with a recommended land size of 8.3 × 8.3 mm for PCB integration.
• Reflow & RoHS — Compatible with lead-free reflow soldering (peak 260°C) and compliant with the RoHS directive per datasheet specifications.

Typical Applications

• Power supply decoupling — Local decoupling for switching regulators and point-of-load stages where low ESR and high-frequency ripple handling reduce voltage ripple.
• DC–DC converters — Bulk and filter capacitor for converter outputs and intermediate rails benefiting from the capacitor's ripple current capability and low ESR.
• Industrial electronics — Use in control modules and instrumentation that require stable capacitance and endurance up to 125°C.
• Power modules and power subsystems — Energy storage and smoothing in compact SMD power assemblies where board space and thermal performance are constrained.

Unique Advantages

• High ripple tolerance: 1.6 A HF ripple and 160 mA LF ripple ratings enable reliable performance in switching and high-frequency circuits.
• Low loss and improved efficiency: 30 mΩ ESR at 100 kHz reduces dissipated heat and helps maintain cleaner supply rails under load.
• Extended high-temperature life: 3,000-hour endurance at 125°C provides predictable aging and endurance for demanding thermal environments.
• Compact SMD can package: φ8 × 8.7 mm radial SMD form factor fits tight PCB layouts while retaining robust capacitance and current capability.
• Reflow and RoHS compliance: Pb‑free reflow compatibility to 260°C and RoHS conformity simplify assembly and regulatory requirements.
