RKS1E270MCNAHGGS

The RKS1E270MCNAHGGS is a surface-mount conductive polymer aluminum electrolytic capacitor in the Nichicon RKS series, rated 27 µF at 25 V. It combines low ESR and high allowable ripple current with long-term high-temperature endurance for compact SMD power designs.

Designed for surface-mount assemblies, this part addresses applications that require stable capacitance at elevated temperatures, controlled loss (tan δ), and reliable ripple handling in high-frequency environments.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20%.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable electrical characteristics and reduced leakage compared to wet electrolytes; tangent of loss angle (tan δ) specified at 0.12 (20°C, 120 Hz).
• Low ESR — Equivalent series resistance of 30 mΩ measured at 20°C/100 kHz, supporting low-loss performance in high-frequency circuits.
• High Ripple Current Capability — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) to accommodate switching and high-frequency power rails.
• High-Temperature Endurance — Rated operating temperature range from −55°C to +125°C with a life (endurance) of 3000 hours at 125°C.
• Leakage Current & Reliability — Leakage current specified at 100 µA; endurance and soldering heat resistance are defined by the RKS series specifications.
• Surface-Mount Can Package — Radial can SMD package, size φ8 × 7.7 mm (diameter × length), supplied in embossed carrier taping with moisture-proof packing for automated placement and reflow.
• Reflow Compatibility & Compliance — SMD reflow capable (series datasheet specifies lead-free reflow conditions up to 260°C peak) and the series is compliant to RoHS directives as stated in the datasheet.

Typical Applications

• Power supply decoupling — Provides bulk decoupling and smoothing on power rails where low ESR and high ripple handling reduce voltage ripple and heating.
• Switching regulator output — Suited for DC–DC converter outputs and switching power stages that demand high-frequency ripple tolerance and stable capacitance at elevated temperatures.
• High-frequency power rails — Effective in compact SMD power modules and boards that require low-loss capacitors with defined ESR at 100 kHz.
• SMD assemblies exposed to elevated temperatures — Designed for assemblies that require long life at +125°C (3000 h endurance) and reflow process compatibility.

Unique Advantages

• Long high-temperature life: 3000 hours at 125°C provides predictable end-of-life behavior for designs operating at elevated temperatures.
• High-frequency performance: 30 mΩ ESR at 100 kHz and 1.6 A ripple at 300 kHz reduce losses in fast-switching circuits.
• Solid polymer stability: Conductive polymer electrolyte delivers controlled tan δ (0.12 at 20°C/120 Hz) and stable leakage specifications.
• Compact SMD form factor: φ8 × 7.7 mm can package and embossed carrier taping enable automated placement and space-efficient board layouts.
• Process-ready: Reflow-compatible construction with datasheet guidance up to 260°C peak supports lead-free assembly flows.
• Defined reliability metrics: Specified ESR, leakage, endurance, and tolerance values allow predictable BOM decisions and system-level thermal/ripple budgeting.
