RKS1V271MCNAJLGS

The RKS1V271MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series, offering 270 µF capacitance at a 35 V rating. It is engineered for general-purpose electronic designs that require high capacitance in a compact SMD radial-can package.

Key highlights include low ESR, high allowable ripple current, a wide operating temperature range, and an extended load life rating — delivering stable performance across demanding thermal and ripple conditions.

Key Features

• Electrical Performance: 270 µF capacitance with ±20% tolerance and a rated voltage of 35 V; tanδ (DF) 0.12 measured at 20°C, 120 Hz.
• Low ESR & High Ripple Handling: ESR of 20 mΩ at 100 kHz and high-frequency ripple current rating of 2 A (at 300 kHz), with 200 mA at 120 Hz for low-frequency ripple.\li>
• Reliability & Endurance: Load life of 3000 hours at 125°C, with specified limits for capacitance change, tanδ and ESR after endurance testing.
• Temperature Range: Operates from −55°C to +125°C, supporting wide thermal environments.
• Package & Mounting: Surface-mount radial can (φ10 × 12.4 L) suitable for automated assembly; supplied in embossed carrier taping with moisture-proof packing.
• Leakage & Stability: Leakage current specified (472 µA) with conditioning and measurement guidance per the datasheet.
• RoHS Compliance: Compliant with RoHS requirements as noted for the series.

Typical Applications

• General-purpose electronic circuits: Provides bulk capacitance for boards and modules where a compact SMD aluminum capacitor is required.
• High-ripple current power sections: Low ESR and a 2 A high-frequency ripple rating make it suitable for circuits subject to elevated ripple currents.
• Thermally demanding assemblies: Rated for −55°C to 125°C and a 3000-hour life at 125°C for applications that require sustained high-temperature performance.

Unique Advantages

• Low ESR for improved AC performance: 20 mΩ at 100 kHz reduces voltage drop and heat generation under high-frequency ripple.
• High allowable ripple current: 2 A at high frequency and 200 mA at low frequency enable use in demanding ripple environments.
• Extended high-temperature life: 3000 hours at 125°C provides predictable end-of-life behavior for long-term designs.
• Wide operating temperature window: −55°C to 125°C supports a broad range of environmental conditions.
• SMD radial-can in compact dimensions: φ10 × 12.4 L package for space-constrained assemblies with automated placement and moisture-proof taped packaging for manufacturing readiness.
• Standards-driven specifications: Datasheet includes soldering profiles, endurance and damp-heat criteria to support qualification and assembly processes.
