RKS1E271MCNAJLGS

The RKS1E271MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon's RKS series, specified at 270 µF and 25 V. It combines high capacitance in a compact radial can SMD package with low equivalent series resistance and high allowable ripple current for demanding power applications.

Designed for general-purpose use, this part targets power-supply decoupling, local energy storage and high-frequency smoothing where long life and wide temperature capability are required.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance rated at 25 V with capacitance tolerance of ±20% (–20%/+20%) at 120 Hz, 20°C.
• Conductive polymer aluminum construction — Solid electrolyte design for stable electrical characteristics and long-term endurance.
• Low ESR & high ripple capability — ESR of 20 mΩ at 100 kHz (20°C) with low-frequency ripple current 200 mA (120 Hz) and high-frequency ripple current up to 2 A (300 kHz).
• Wide temperature and endurance — Operating range –55°C to +125°C and rated load life of 3000 hours at 125°C.
• Leakage current — Specified leakage current of 337 µA after application of rated voltage.
• Surface-mount radial can package — Size φ10 × 12.4 mm with embossed carrier taping and moisture-proof packing for automated assembly; compatible with lead-free reflow soldering up to 260°C per datasheet limits.

Typical Applications

• Power supply decoupling — Local energy storage and smoothing for DC power rails, leveraging 270 µF capacitance and low ESR to reduce voltage ripple.
• High-frequency power stabilization — Supports high-frequency ripple currents (up to 2 A at 300 kHz) for switching regulators and converters.
• General-purpose SMD capacitor — Surface-mount radial can option for designs requiring compact, high-capacitance components with long-term thermal endurance.

Unique Advantages

• High allowable ripple current: Supports both low-frequency (200 mA at 120 Hz) and high-frequency (2 A at 300 kHz) ripple demands to improve regulator stability and thermal margin.
• Very low ESR: 20 mΩ at 100 kHz (20°C) minimizes loss and heat generation under dynamic load conditions.
• Robust thermal endurance: Rated for –55°C to +125°C with 3000-hour life at 125°C for extended reliability in high-temperature environments.
• SMD-friendly packaging: Embossed carrier taping and moisture-proof packing enable automated placement and standard reflow processing up to the datasheet-specified peak temperature.
• Measurable leakage performance: Specified leakage current (337 µA) and datasheet conditioning/test procedures help validate design margins for standby and powered states.
